Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a rod-shaped motor mover. Background Technology

[0002] Rod motors are commonly used in automated production lines, robotic arm drives, conveyor systems, and automotive shock absorbers. To avoid unauthorized connections between coils, existing rod motors use relatively small coil diameters to allow space for cable routing. However, smaller coils increase the gap between the coil and the stator (magnet), reducing motor output. Simultaneously, smaller coils lead to a decrease in magnetic field strength, further reducing motor output. Utility Model Content

[0007] Furthermore, the upper guide ring is provided with three L-shaped grooves, which extend from the top of the inner side of the upper guide ring to the bottom of the inner side, and then from the inner side of the bottom to the outer side of the bottom.

[0008] Furthermore, the lower guide ring is provided with three clearance slots, and one end of each of the three phase wires of the bottom coil is routed through and connected to the other three clearance slots.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] Please refer to Figures 1-5The rod-shaped motor actuator of this utility model embodiment includes a main shaft and a coil assembly. The coil assembly consists of several groups of coils sequentially sleeved on the main shaft, with teeth between the coils and the coils being separated by the teeth. A yoke is provided on the main shaft corresponding to the upper side of the top coil (uppermost coil) and the lower side of the bottom coil (lowest coil). That is, the teeth are located between the coils of the coil assembly, and the yokes are located at both ends of the coil assembly.

[0024] The coil has three recessed sections on its outer periphery, which are concave inwards compared to the coil's outer circumference. If the recessed sections are large, only one recessed section can be provided, from which the three phase wires (UVW) of the coil are led out. This invention incorporates wiring recessed sections on the circular surface of the circular coil, providing space for wiring between coils and for passing wires, while maintaining the maximum outer diameter of the coil to ensure optimal motor output.

[0025] Three sets of wire slots are provided on the outer periphery of both the yoke and the teeth. The three-phase wires of the coil (i.e., UVW three-phase wires) are led out from the three clearance sections respectively (the inlet and outlet ends of the UVW three-phase wires are led out from the clearance sections). The coils of the coil assembly are connected in series or in parallel through the wire slots on the teeth.

[0026] This invention can make the outer diameter of the motor coil and the outer diameter of the teeth the same, thereby minimizing the gap between the coil and the stator and increasing the motor output.

[0027] In one implementation, an upper guide ring and a lower guide ring are respectively provided at the upper and lower ends of the main shaft. The upper and lower guide rings guide the movement of the mover in the stator. The upper guide ring has three L-shaped grooves, which extend from the top inner side to the bottom inner side, and then from the inner bottom side to the outer bottom side. The lead-out end of the top coil passes through the wire groove and the L-shaped groove on the upper yoke to connect to the motor power line. The surface of the motor power line has an insulating layer (i.e., insulating enamel) to ensure that the motor power line does not conduct when passing through the main shaft, making the motor resistant to high voltage.

[0028] In one implementation, the lower guide ring is provided with three clearance slots. The output ends of the three-phase wires of the bottom coil pass through the wire slots and clearance slots on the lower yoke and are then connected. The lower guide ring has a large internal space, and this invention utilizes the space of the lower guide ring for wiring, which facilitates the connection and insulation of the common terminal.

[0029] In one implementation, the spindle is provided with an anti-rotation groove, and positioning blocks are correspondingly provided on the inner sides of the upper and lower guide rings. The positioning blocks are embedded in the anti-rotation groove, facilitating the installation and positioning of the upper and lower guide rings.

[0030] In one implementation, a locking nut is provided on the spindle corresponding to the screw connection (i.e., via a threaded connection). The locking nut secures and fixes the upper guide ring, lower guide ring, coil assembly, etc.

[0031] As one implementation method, buffer pads are provided on the upper and lower sides of the main shaft to prevent damage to the mover during movement.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
