[0006] FIELD OF THE INVENTION
[0007] This invention generally relates to modular linear actuators and actuator assemblies that can include modular linear actuators.
[0008] BACKGROUND OF THE INVENTION
[0009] A linear actuator is designed to convert rotational motion from a motor into linear motion, such as for providing the force necessary to move and position an object or a piece of equipment. Conventional applications for linear actuators include straight push / pull movements, as well as lifting and tilting movements. There remains a need, however, for improvements of linear actuators in terms of at least one of performance, cost, operability, and functionality.
[0010] SUMMARY OF THE INVENTION
[0011] Aspects of the invention provide for modular linear actuators and actuator assemblies that can include modular linear actuators.
[0012] According to one aspect of the invention, a modular actuator assembly is disclosed. The modular actuator assembly includes a latch selected from a plurality of latches and a modular linear actuator directly or indirectly coupled to the selected latch. The modular linear actuator includes a motor housing and an output housing. The motor housing extends along a central axis between a proximal section and an opposite distal section. The motor housing defines a motor interface surface. The output housing extends along the central axis between a proximal output section adjacent to the motor and an opposite distal output section. The output housing defines an output interface surface. One of the motor interface surface and the output interface surface has a flange section extending radially outwardly relative to the central axis and the other of the motor interface surface and the output interface surface has a2103102-002122

[0014] corresponding groove section configured for releasable engagement with the flange section, thereby preventing axial movement of at least the output housing and the motor housing relative to each other.
[0015] According to another aspect of the invention, modular linear actuator is disclosed. The modular linear actuator includes a motor housing and an output housing. The motor housing extends along a central axis between a proximal section and an opposite distal section. The motor housing defines a motor interface surface. The output housing extends along the central axis between a proximal output section adjacent to the motor and an opposite distal output section. The output housing defines an output interface surface. One of the motor interface surface and the output interface surface has a flange section extending radially outwardly relative to the central axis and the other of the motor interface surface and the output interface surface has a corresponding groove section configured for releasable engagement with the flange section, thereby preventing axial movement of at least the output housing and the motor housing relative to each other.
[0016] According to a still another aspect of the invention, a method of assembling a modular actuator assembly is disclosed. The method includes steps of: selecting from a plurality of motor housings a motor housing defining a motor interface surface; selecting from a plurality of output housings an output housing defining an output interface surface; and engaging a flange section of one of the motor interface surface and the output interface surface with a corresponding groove section of the other of the motor interface surface and the output interface, thereby preventing axial movement of at least the output housing and the motor housing relative to each other.
[0017] Still another aspect of the invention is directed to a motor housing of a modular actuator assembly. The motor housing includes a body extending along a central axis between a proximal section and an opposite distal section.

[0060] DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.
[0061] Furthermore, one of skill in the art would readily be able to utilize various aspects of the embodiments in different fields of endeavor.
[0062] Additionally, various forms and embodiments of the invention are illustrated in the figures. It will be appreciated that the combination and arrangement of some or all features of any of the embodiments with other embodiments is specifically contemplated herein. Accordingly, this detailed disclosure expressly includes the specific embodiments illustrated herein, combinations and subcombinations of features of the illustrated embodiments, and variations of the illustrated embodiments.
[0063] Various terms are used throughout the disclosure to describe the physical shape or arrangement of features. A number of these terms are used to describe features that conform to a cylindrical or generally cylindrical geometry characterized by a radius and a center axis perpendicular to the radius. Unless a different meaning is specified, the terms are given the following meanings. The terms "longitudinal", "longitudinally", "axial" and "axially" refer to a direction, dimension or orientation that is parallel to a center axis. The terms "radial" and "radially" refer to a direction, dimension or orientation that is perpendicular to the center axis. The terms "inward" and "inwardly" refer to a direction, dimension or orientation that extends in a radial direction toward the center axis. The terms "outward" and "outwardly" refer to a direction, dimension or orientation that extends in a radial direction away from the center axis.
[0064] In the description, relative terms such as "left," "right," "horizontal," "vertical," "up," "down," "top" and "bottom" as well as derivatives thereof (e.g., "horizontally," "downwardly," "upwardly," etc.) should be construed to refer to the orientation as then described or as shown in the drawing figure under discussion.2103102-002122
[0065] -6-
[0066] These relative terms are for convenience of description and normally are not intended to require a particular orientation.
[0067] Terms concerning attachments, coupling and the like, such as "mounted," "connected" and "interconnected," refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise.
[0068] According to aspects of the invention, an electric linear actuator has an output section comprising a rod driven by a motor via a screw (e.g. lead screw, ball screw, roller screw, worm gear, etc.) and may include an internal gearbox. When power is applied to the linear actuator, the rod begins to translate, until the motor is deactivated (e.g. power is cut off). The power cut off signal typically comes from a limit switch, which thus controls the stroke (e.g. push / pul I force and movement) of the rod by cutting off the power when the rod reaches a certain point.
[0069] Generally, embodiments of this invention make it possible to facilitate interchangeability of multiple components of the linear actuator and / or an assembly comprising the liner actuator, thereby decreasing costs associated with manufacture of components limited to a single type or function. To achieve this, the exemplary linear actuator is designed to include components, each having an interface, configured to be adaptable to various scenarios and customer needs. Thus, embodiments of a linear actuator as described herein can simplify the overall design, yet be adaptable for a multitude of various uses. Non-limiting examples of the various applications of the exemplary linear actuator are illustrated in FIGS. 1A-1D (first embodiment of an assembled linear actuator); FIGS. 2A-2D (second embodiment of an assembled linear actuator); FIGS. 3A-3D (third embodiment of an assembled linear actuator); FIGS. 4A-4D (fourth embodiment of an assembled linear actuator); and FIGS. 5A-5D (fifth embodiment of an assembled linear actuator. Details of exemplary latch applications including the exemplar linear actuator or actuator assemblies described herein are as described in U.S. Pat. No. 12,215,524 and U.S. Pat. No. 7,455,335, both of which are incorporated herein by reference. However, one skilled in the art would understand from the description herein that the application of linear actuator is not limited to the certain illustrated latches, but other applications may be readily apparent and within the spirit and scope of this invention. For example, the exemplary linear actuator may be generally used to facilitate movement (e.g. lifted, lowered, pushed, pulled, positioned, etc.) of an object or equipment. In an exemplary embodiment, the linear actuator may be used to moved cable systems, means for position control, or systems requiring linear motion and / or rotational motion.2103102-002122
[0070] -7-
[0071] Referring now to FIGS. 6, 10A-10E, and 11A-11E, an exemplary embodiment of a linear actuator in accordance with aspects of the invention is depicted. As a general overview, a linear actuator 100 includes an output housing 110 and a motor housing 122. Generally, one or more components of linear actuator 100 are affixed to other(s) of the one or more components by way of well-known means, including welding, adhesives, riveting, or other fastening or affixing means.
[0072] In an exemplary embodiment, as best shown in FIGS. 8A-8E, the output housing 110 extends along a central axis ("A" in FIG. 8D) between a first (or proximal) output section Illa and a second (or distal) output section 111b. As illustrated in FIGS. 8A-8E, output housing 110 generally has a rectangular geometry showing a cavity 112 bounded by irregular borders, but one skilled in the art would appreciate from the description herein that output housing 110 may have a geometry based on the size and shape of one or more components of the linear actuator 100, including but not limited to the worm gear 130 and an output 140. Further, although FIG. 6 illustrates the output housing 110 are as being separate components configured to be attached to one another, e.g., a first output housing portion 110a and a second output housing portion 110b are attached to one another by known attachment means (e.g., adhesives, fasteners, etc.), for example, the output housing 110 may also be integrally formed as a unitary body in other embodiments.
[0073] Still further, although FIGS. 8A-8E only illustrates that second output housing portion section 110b, one skilled in the art would understand from the description herein and in conjunction with FIG. 6, that first output housing portion 110a may have a size, shape, and overall geometry that are complementary to second output housing portion 110b, such that together, first output housing portion 110a and a second output housing portion 110b are configured to at least partially house or enclose one or more components of the linear actuator 100. In one non-limiting example, the output housing 110 is configured to partially or entirely house at least the worm gear 130 and the output, such as elongated rod 140. Thus, the geometries of first output housing portion 110a and second output housing portion 110b are complementary, such that together, a contoured surface corresponding to at least the worm gear 130 and the output 140 is at least partially secured within the space formed by output housing 110.
[0074] In an exemplary embodiment, as best shown in FIGS. 6 and 7A-7E, linear actuator 100 includes a motor housing 122 extending along the central axis ("A"' in FIG. 7E) between a proximal section 122a and an opposite distal section 122b. The central axis A' of the motor housing 122 may be aligned with the central axis A of the output housing 100 when they are assembled together to form linear actuator 100 (as2103102-002122
[0075] -8-
[0076] shown in FIGS. 10A-10E and 11A-11E). In an exemplary embodiment, as illustrated in FIGS. 7A-7E, the motor housing 122 is integrally formed as a single body of unitary construction. However, one skilled in the art would understand from the description herein that the motor housing 122 can be formed from one or more structures which together define a cavity or space, with motor 120 being positionable within the space of the motor housing 122.
[0077] Further, the motor housing 122 generally has a rectangular geometry showing a cavity or space bounded by regular borders, but one skilled in the art would appreciate from the description herein that motor housing 122 may have a geometry based on the size and shape of one or more components of the linear actuator 100, including but not limited to the motor 120. To facilitate this, the motor housing 122 may include a cover 124 positionable adjacent or attached to the proximal section 122a of the motor housing 122, thereby enclosing the motor 120 within the motor housing 122. Additionally or optionally, cover 124 may provide means of attaching linear actuator 100 to one or more components of an actuator assembly (e.g. actuator assembly 1000 as discussed below). Additionally or optionally, an opening defined on the cover 124 may be formed to facilitate connection of motor 120 to a power source (not shown). Still further, the linear actuator 100 includes a seal 126. The seal 126 is provided to seal between the worm gear 130 and the motor housing 122. That seal 126, along with sealing the motor wires in the motor covers (e.g., of the motor housing 122), allows the motor cavity (e.g., cavity or space defined by the motor housing 122) to be completely sealed. That way no liquid or dust can get into the motor housing 122 to cause damage to the operational components of actuator 100, such as motor 120. This allows use of the actuator 100 in various environments while reducing or preventing the ingress of unwanted media like water into the motor housing 122 that may cause the actuator 100 to fail or to be compromised.
[0078] As best shown in FIGS. 6 and 9A-9B, in an assembled form, the motor housing 122 is positionable adjacent the output housing 110. In an exemplary embodiment, the first (or proximal) output section Illa of the output housing 110 is positionable adjacent the distal section 122b of the motor housing 122. In this configuration, the motor housing 122 defines a motor interface surface 170 and output housing 110 defines an output interface surface 180. In an exemplary embodiment, the motor interface surface 170 and output housing 110 together define a passageway to facilitate passage of worm gear 130 to connect to at least a portion of motor shaft 128 (FIG. 5B), which is positioned at least partially within the motor housing 122 or the output housing 110 when linear actuator 100 is assembled. Motor shaft 128 has a longitudinal axis that is parallel or coaxial with the central axes A, A'. Various2103102-002122
[0079] -9-
[0080] dimensions of the motor shaft 128, including non-uniform widths, lengths, cross-sectional shapes and circumferences, will be understood by one of skill in the art from the description herein.
[0081] In a further exemplary embodiment, to facilitate a releasable attachment between the motor housing 122 and the output housing 110, the motor interface surface 170 and the output interface surface 180 may have a size, shape, and geometry that are complementary. Thus, in one non-limiting example, one of the motor interface surface 170 and the output interface surface 180 has a flange section 172 extending radially outwardly relative to the central axis A' (FIG. 7D-7E).
[0082] Additionally or optionally, the other of the motor interface surface 170 and the output interface surface 180 has a corresponding groove section 182 configured for releasable engagement with the flange section 172, thereby preventing axial movement of at least the output housing 110 and the motor housing 122 relative to each other when linear actuator 100 is assembled. Accordingly, in this way, the modular linear actuator 100 is configured for engagement of the motor housing 122 to the output housing 110, disengagement of the motor housing 122 from the output housing 110, and engagement of an alternate motor housing 122' (e.g., such as the various non-limiting motor housings 122' shown in FIGS. 1A to 5D) or an alternate output housing 110' e.g., such as the various non-limiting output housings 110' shown in FIGS. 1A to 5D) for retrofit of the motor housing 122 or the output housing 110 with the alternate motor housing 122' or alternate output housing 110', respectively. In an exemplary embodiment, the flange section 172 and the groove section 182 each define complementary or corresponding mounting tabs which form an interference fit when the output housing 110 and the motor housing 122 are releasably attached to each another. In some embodiments, the output housing 110 and the motor housing 122 may be permanently assembled once. For example, in embodiments in which laser welding of one or more of the housings is performed, it may be prevented from being disassembled and reconfigured.
[0083] Still further, as shown in FIGS. 9A-9B, a worm gear 130 is disposed within the output housing 110. In an exemplary embodiment, worm gear 130 has a generally elongated body which defines a longitudinal axis that is parallel to or coaxial with the central axes A. In a non-limiting example, an end portion of the worm gear 130 is engageably coupled directly or indirectly to the shaft 128. In this configuration, the worm gear 130 rotates about a rotation axis in response to motion of the shaft 128. The rotation axis is parallel to the central axis A. Additionally or optionally, worm gear 130 has a threaded surface and a non-threaded surface, including a proximal nonthreaded surface closer to the motor shaft 128. In a non-limiting example, as2103102-002122
[0084] -10-
[0085] illustrated in FIG. 6, the worm gear 130 has the threaded surface along a majority of the portion of the body. The configuration of the threaded surface and non-threaded surface may depend, in part, on the desired characteristics of the travel of the output 140 (discussed below) or the overall application of the linear actuator 100.
[0086] In an exemplary embodiment, as best shown in FIGS. 6, 10A-10E, and FIGS. 11A-11E, the output 140 comprises an elongated rod having a rod engagement surface 142 (FIG. 9B) disposed within the rod housing 110, and an arm 144 extending outside the rod housing 110. Although the output 140 is illustrated as being integrally formed as a single body of unitary construction, one of ordinary skill in the art would understand from the description herein that output 140 may be comprised of separate components, e.g. rod engagement surface 142 and arm 144. In an exemplary embodiment, rod engagement surface 142 comprises a space 160. Additionally or optionally, the rod engagement surface 142 is biased to be positioned radially outward relative to the rotation axis of the worm gear 130 when traveling between a retracted position, such as a proximal position relative to the motor 120, and an extended position, such as a distal position relative to the motor 120. Additionally or optionally, space 160 may facilitate passage of worm gear 130 therethrough, as best illustrated in cross-sectional views of FIGS. 9A-9B, and thus convert rotational motion of worm gear 130 to translational motion of output 140 relative to output housing 110. To achieve this, the rod engagement surface 142 is configured to be engageably coupled directly or indirectly to the worm gear 130. The geometry of components of the output housing 110 and output 140, as illustrated in FIGS. 10A-10E and 11A-11E, are not intended to be limiting.
[0087] In still another exemplary embodiment, a releasable attachment between the output housing 110 and the output 140 is additionally or optionally provided, such that at least the output interface surface 180 may have a size, shape, and geometry that is complementary to the output 140 or alternate output 140' selected from a plurality of outputs 140. In one non-limiting example, the modular linear actuator 100 is configured for engagement of the output housing 110 to the output 140, disengagement of the output housing 110 from the output 140, and engagement of an alternate output housing 110' (e.g., such as the various non-limiting output housings 110' shown in FIGS. 1A to 5D) or an alternate output 140' (e.g., such as the various non-limiting output 140' shown in FIGS. 1A to 5D) for retrofit of the output housing 110 or the output 140 with the alternate output housing 110' or the alternate output 140', respectively. In an exemplary embodiment, the interchangeability of the output 140 relative to the output housing 110 is achieved in similar respect as described above with respect to the flange section 172 / groove section 180 interface 190 (FIGS.2103102-002122
[0088] -11-
[0089] 9A-9B) between the motor housing 122 and the output housing 110. In another exemplary embodiment, the rod engagement surface 142 which is configured to slide within the output housing 140 around the threaded surface of the worm gear 130 permit interchangeability of output 140 / 140'. Additionally or optionally, the modular actuator assembly 1000 is configured for disengagement of the motor 120 from another component of the modular actuator assembly 1000, and engagement of an alternate motor 120' for retrofit of the motor 120 with the alternate motor 120'.
[0090] For example, the arm 144 which extends external of the output housing 110 can be modified, such as by changing the arm / pin 144 size or length or changing the geometry of the arm 144 to a deadbolt shape. In this way, the output 140 of the linear actuator 100 has the arm 144 is configured to move between locked and unlocked states. Referring to FIG. 13, linear actuator 100 may be mounted on a component 300 (e.g., panel, door, frame, etc.). In the locked state, the arm 144 is positioned to restrict access to an interior (e.g., as defined by a frame and component 1300 movable relative to the frame), and, in the unlocked state, the arm 144 is positioned to permit access to the interior. Additionally or optionally, plural linear actuators 100a, 100b (not limited to the number of linear actuators 100 depicted in FIG. 13, for example) may be employed and together, the plural linear actuators are movable between locked and unlocked states for permitting or restricting access to the interior, respectively.
[0091] The functionality of the aforementioned features will now be discussed in more detail below. Embodiments of the present invention make it possible to facilitate interchangeability of multiple components of the linear actuator and / or an assembly comprising the liner actuator, thereby decreasing costs associated with manufacture of components limited to a single type or function. To achieve this, the exemplary linear actuator is designed to include components, each having an interface, configured to be adaptable to various scenarios and customer needs. Thus, embodiments of a linear actuator as described herein can simplify the overall design, yet be adaptable for a multitude of various uses.
[0092] In an exemplary embodiment, and with reference to FIGS. 6, 10A-10E (when output 140 is in a retracted position), and 11A-11E (when output 140 is in an extended position), when the motor 120 is activated and motor shaft 128 rotates, worm gear 130 rotates in response to motion of the motor shaft 128. As the worm gear rotates, at least the rod engagement surface 142, which is configured to be engageably coupled directly or indirectly to the worm gear 130, translates. To be translated to the extended position from the retracted position, the output 140 translates in response to rotation of the worm gear 130 along a first rotational direction (e.g. counterclockwise2103102-002122
[0093] -12-
[0094] or clockwise). In a non-limiting example, the motor 120 is configured to rotate the shaft 128 in the first rotational direction to cause the worm gear 130 to rotate in the first rotational direction, thereby permitting or causing movement of the output 140 toward the extended position (e.g., along a direction of arrow "X" as depicted in FIG.
[0095] 11D). Additionally or optionally, at least the arm 144 of output 140 is a distance (D') away from a surface of second section 111b of the output housing 110 at the extended position, as shown in FIG. 11D.
[0096] Conversely, to be translated to the retracted position from the extended position, the output 140 translates in response to rotation of the worm gear 130 along a second rotational direction (e.g. counterclockwise or clockwise). In a non-limiting example, the motor 120 is configured to rotate the shaft 128 in the second rotational direction to cause the worm gear 130 to rotate in the second rotational direction, thereby permitting or causing movement of the output 140 toward the retracted position (e.g. along a direction of arrow "Y" as depicted in FIG. 10D). In an exemplary embodiment, the second rotational direction is different from the first rotational direction. In an exemplary embodiment, at least the arm 144 of output 140 is a distance (D) away from second section 111b of the output housing 110 at the retracted position, as shown in FIG. 10D.
[0097] Assemblies and / or systems employing embodiments of the present invention include modular actuator assemblies, such as actuator assembly 1000, are illustrated schematically in FIGS. 12A-12B. In an exemplary embodiment, actuator assembly 1000 may also be equipped with a latching mechanism, such as latch 1200. Additionally or optionally, latch 1200 is one or more of a compression latch, a rotary latch, a pull latch, or an electro-mechanical latch.
[0098] In an exemplary embodiment, as shown in FIG. 12A, a component 1300 (e.g. a movable door or panel) is provided. In a non-limiting example, mounted on component 1300 is a linear actuator, such as linear actuator 100. Additionally or optionally, also mounted on component 1300 is latch 1200, which is directly or indirectly coupled to the linear actuator 100. In this way, operation of linear actuator 100 may facilitate movement of latch 1200 between a latched position in which access to an interior defined by a frame and component 1300 movable relative to the frame, is restricted or prevented and an unlatched position in which access to the interior is permitted. In an exemplary embodiment, linear actuator 100 moves a mechanical lock plug from the locked to unlocked position, thereby allowing the latch 1200 to move between latched and unlatched states, respectively.2103102-002122
[0099] -13-
[0100] In another exemplary embodiment, as shown in FIG. 12B, mounted on component 1300 is a linear actuator, such as linear actuator 100, and plural latches 1200, such as latches 1200a, 1200b, each of which are each directly or indirectly coupled to the linear actuator 100. In this configuration, operation of linear actuator 100 may facilitate movement of latches 1200a, 1200b between a latched position in which access to the interior is restricted or prevented and an unlatched position in which access to the interior is permitted.
[0101] Although discussed in relation to latches, one skilled in the art would understand from the description herein that the application of linear actuator 100 is not limited to latches, but other applications may be readily apparent and within the spirit and scope of this invention. For example, linear actuator 100 may be used to facilitate movement (e.g. lifted, lowered, pushed, pulled, positioned, etc.) of an object or equipment. In an exemplary embodiment, linear actuator 100 may be used to moved cable systems, means for position control, or systems requiring linear motion and / or rotational motion.
[0102] Still further, a method of assembling a modular actuator assembly is provided and discussed in context with the actuator assemblies 1000 and linear actuator 100 as described above. Turning now to FIG. 14, an exemplary method, such as method 3000, includes the following steps of: selecting from a plurality of motor housings a motor housing defining a motor interface surface; selecting from a plurality of output housings an output housing defining an output interface surface; engaging a flange section of one of the motor interface surface and the output interface surface with a corresponding groove section of the other of the motor interface surface and the output interface, thereby preventing axial movement of at least the output housing and the motor housing relative to each other.
[0103] In one embodiment, method 3000 includes step 3010 of selecting from a plurality of motor housings, a motor housing defining a motor interface surface. In one non-limiting example, the selected motor housing includes a motor housing 122 as described above. In an exemplary embodiment, as illustrated in FIGS. 7A-7E, the motor housing 122 is integrally formed as a single body of unitary construction.
[0104] However, one skilled in the art would understand from the description herein that the motor housing 122 can be formed from one or more structures which together define a cavity or space, with motor 120 being positionable within the space of the motor housing 122.
[0105] In an exemplary embodiment, method 3000 includes step 3020 of selecting from a plurality of output housings, an output housing defining an output interface2103102-002122
[0106] -14-
[0107] surface. In one non-limiting example, the selected output housing includes output housing 110 as described above. In an exemplary embodiment, as illustrated in FIG. 6, the output housing 110 is formed of separate components configured to be attached to one another, e.g., a first output housing portion 110a and a second output housing portion 110b are attached to one another by known attachment means, for example, the output housing 110 may also be integrally formed as a unitary body.
[0108] In an exemplary embodiment, method 3000 includes step 3030 of engaging a flange section of one of the motor interface surface and the output interface surface with a corresponding groove section of the other of the motor interface surface and the output interface, thereby preventing axial movement of at least the output housing and the motor housing relative to each other. In a non-limiting example, the motor housing 122 defines a motor interface surface 170 and output housing 110 defines an output interface surface 180. The motor interface surface 170 and output interface surface 180 together define a passageway to facilitate passage of worm gear 130 to connect to at least a portion of motor shaft 128 (FIG. 5B), which is positioned at least partially within the motor housing 122 or the output housing 110. Additionally or optionally, to facilitate a releasable attachment between the motor housing 122 and the output housing 110, the motor interface surface 170 and the output interface surface 180 may have a size, shape, and geometry that are complementary. Thus, in one non-limiting example, one of the motor interface surface 170 and the output interface surface 180 has a flange section 172 extending radially outwardly relative to the central axis A' (FIG. 7D-7E). Additionally or optionally, the other of the motor interface surface 170 and the output interface surface 180 has a corresponding groove section 182 configured for releasable engagement with the flange section 172, thereby preventing axial movement of at least the output housing 110 and the motor housing 122 relative to each other when linear actuator 100 is assembled.
[0109] Accordingly, in this way, method 3000 includes a further step of the modular actuator assembly comprising a linear actuator 100 being configured for engagement of the motor housing 122 to the output housing 110, disengagement of the motor housing 122 from the output housing 110, and engagement of an alternate motor housing 122' (e.g., such as the various non-limiting motor housings 122' shown in FIGS. 1A to 5D) or an alternate output housing 110' e.g., such as the various non-limiting output housings 110' shown in FIGS. 1A to 5D) for retrofit of the motor housing 122 or the output housing 110 with the alternate motor housing 122' or alternate output housing 110', respectively. In an exemplary embodiment, the flange section 172 and the groove section 182 each define complementary or corresponding mounting tabs which2103102-002122
[0110] -15-
[0111] form an interference fit when the output housing 110 and the motor housing 122 are releasably attached to each another.
