[0002] Linear motors are widely used in automation. Conventional linear motors consist only of a stator and a moving part. To achieve linear feed, users must mount the stator on a base, fix the mover on a slide, and install a linear rolling guide between the base and the slide. The guide rails in the guide are fixed to the base, and the slider in the guide is fixed to the working slide. A specialized drive system then supplies alternating current to the mover coil to achieve movement relative to the stator. Besides the mover, the moving parts of such linear motors include machined and purchased components such as the working slide and slider, making the equipment structure, manufacturing, installation, and debugging processes complex, and resulting in a large footprint.

Detailed Implementation

[0021] The utility model objective of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation of this utility model is not limited to the following embodiments.

[0022] In this implementation, in the first direction a, the arrow points to the right and to the left; in the second direction b, the arrow points to the rear and to the front; and in the third direction c, the arrow points to the top and to the bottom.

[0023] like Figure 1-3 As shown, an integrated linear motor slide table with an embedded track includes a support base 1, a silicon steel sheet assembly 2, six coils 3, a sliding base 4, two sliding components 5, a stator assembly 6, and an embedded track base 7. Each sliding component 5 includes a fixed guide rail 501, multiple ball bearings 502, a movable slide rail 503, and two reversers. Each reverser includes a reverse block 504 and a fixed plate 505. The middle of the bottom of the support base 1 is connected to the top of the silicon steel sheet assembly 2, and both the front and rear ends of the bottom of the support base 1 are connected to the top of the sliding base 4. The silicon steel sheet assembly 2 is inserted into the six coils 3. The six coils 3 are installed inside the sliding base 4. The two movable slide rails 503 are respectively installed on the front and rear ends of the sliding base 4. The two movable slide rails 503 and the two fixed guide rails 501 form a moving channel, and the two fixed guide rails 501 are respectively installed on the front and rear inner sides of the embedded track base 7. The two ends of the two movable slide rails 503 are connected to the two ends of the two return flow holes 407 of the sliding base 4 through four reversing blocks 504. The reversing blocks 504 and the return flow holes 407 form a return channel, and multiple ball bearings 502 are installed in the movable channel and the return channel respectively. The stator assembly 6 consists of six flat stators, which are evenly laid in the embedded track base 7 and connected in sequence. The silicon steel sheet assembly 2 corresponds to the six flat stators.

[0024] The support base 1 is used to mount external parts and drive them to move left and right in the first direction a. The silicon steel sheet assembly 2 serves as the secondary magnetic circuit carrier for the track-embedded linear motor integrated mover slide, optimizing magnetic field transmission efficiency. The stacked structure of the silicon steel sheet assembly 2 significantly reduces eddy current losses and improves motor response speed and energy efficiency. When the coil 3 is energized, it generates a traveling wave magnetic field, which interacts with the magnetic field of the silicon steel sheet assembly 2 to produce electromagnetic thrust, directly driving the linear motion of the sliding base 4. The sliding base 4 serves as the power transmission hub and the carrier for the ball bearing circulation channel. The sliding assembly 5 provides low-friction guidance for the sliding base 4. The stator assembly 6 provides the physical support surface for the magnetic field, forming a closed magnetic circuit with the silicon steel sheet assembly 2. The uniformly laid-out design ensures continuous magnetic field line distribution, reducing edge effects that cause thrust fluctuations. The embedded track base 7 serves as the system's basic frame, integrating the stator assembly 6 and providing high-rigidity support. The fixed guide rail 501 serves as a static track, while the movable slide rail 503 serves as a dynamic track. The fixed guide rail 501 and the movable slide rail 503 achieve low-friction guidance through the circulation of balls 502. The balls 502 roll within the fixed guide rail 501 and the movable slide rail 503, converting sliding friction into rolling friction to support high-acceleration motion. A reverser guides the balls 502 to change direction between the moving channel and the return channel. The return channel consists of a reverse block 504 and a return flow hole 407, allowing the balls 502, which have left the load area, to return to their starting point with low resistance, maintaining rolling continuity.

[0025] like Figure 4 As shown, the supporting base 1 includes two limiting side plates 101 and a supporting bottom plate 102. The two ends of the supporting bottom plate 102 are perpendicularly connected to the lower ends of the two limiting side plates 101, respectively. The upper ends of the two limiting side plates 101 protrude from the top of the supporting bottom plate 102. The middle of the bottom surface of the supporting bottom plate 102 is connected to the top of the silicon steel sheet assembly 2, and the front and rear ends of the bottom of the supporting bottom plate 102 are respectively connected to the two sliding side rods 401 of the sliding base 4.

[0026] like Figure 5 As shown, the silicon steel sheet assembly 2 includes a silicon steel base plate 201, two silicon steel side plates 202, and six silicon steel middle plates 203. The two silicon steel side plates 202 are perpendicularly connected to the left and right ends of the silicon steel base plate 201, respectively. The six silicon steel middle plates 203 are all perpendicularly connected to the bottom center of the silicon steel base plate 201. The six silicon steel middle plates 203 are arranged sequentially. The silicon steel side plates 202 and the six silicon steel middle plates 203 are parallel to each other. The six silicon steel middle plates 203 are inserted into the six coils 3, respectively. The silicon steel side plates 202 are inserted into the second silicon steel slot 405 of the sliding base 4, and are located outside the coils 3. The top of the silicon steel base plate 201 is connected to the bearing base 1. The silicon steel side plates 202 and the silicon steel middle plates 203 form a first slot 204, and the two silicon steel middle plates 203 form a second slot 205. The coils 3 are respectively limited within the second slot 205, and the connecting plate 402 of the sliding base 4 is limited within the first slot 204.

[0027] The silicon steel base plate 201 serves as the main magnetic flux conduction plane, connecting the silicon steel side plates 202 and the silicon steel middle plate 203 to form a closed loop of magnetic field lines. The silicon steel base plate 201, the two silicon steel side plates 202, and the silicon steel middle plate 203 are used to directly conduct alternating magnetic flux.

[0028] like Figure 6 As shown, the sliding base 4 includes two sliding side rods 401, two connecting plates 402, and five segmented middle plates 403. The left and right ends of the two sliding side rods 401 are connected by the two connecting plates 402. The two sliding side rods 401 and the two connecting plates 402 form a silicon steel mounting cavity. The two ends of the five segmented middle plates 403 are connected to the inner sidewalls of the sliding side rods 401. The five segmented middle plates 403 are located within the silicon steel mounting cavity, are parallel to each other, and are parallel to the connecting plates 402. The connecting plates 402 and the segmented middle plates 403 form two first silicon steel slots 404, and four second silicon steel slots 405 are formed between adjacent segmented middle plates 403. Six coils 3 are respectively installed in the two first silicon steel slots 404 and the four second silicon steel slots 405. A return flow hole 407 is provided at the lower end of each of the two sliding side rods 401, and the two ends of each return flow hole 407 are connected to two inverters. A first rail groove 406 is provided on the outer side of each of the two sliding side rods 401. The moving rail 503 of the sliding assembly 5 is installed in the first rail groove 406.

[0029] The sliding side rod 401 serves as the main frame of the base, bearing the bending moment of the electromagnetic thrust and external load. The return flow hole 407 connects to the reverser, forming a return channel for the ball bearing 502, enabling infinite stroke circulation. The outer first rail groove 406 is used to install the moving slide rail 503. The connecting plate 402 connects the left and right ends of the two sliding side rods 401, forming a closed silicon steel mounting cavity. The dividing middle plate 403 divides the silicon steel mounting cavity into six independent compartments, corresponding to the six coil 3 mounting positions.

[0030] like Figure 7 As shown, the embedded track base 7 includes a guide base plate 701 and two guide side plates 702. The two ends of the guide base plate 701 are perpendicularly connected to the lower ends of the guide side plates 702, and the two guide side plates 702 are parallel to each other. Each guide side plate 702 has a second track groove 7021 on its inner side, and two fixed guide rails 501 are respectively installed in the two second track grooves 7021. A stator fixing groove 7011 is provided on the top of the guide base plate 701, and the flat stators of the stator assembly 6 are sequentially installed in the stator fixing groove 7011.

[0031] like Figure 1 and 2 As shown, the stator assembly 6 includes six flat stators, which are sequentially installed in the stator fixing groove 7011 at the bottom of the embedded track.

[0032] The working process of an integrated linear motor mover slide table with an embedded track is described as follows: An external power supply inputs current to six coils 3, which generate a traveling wave magnetic field after being energized. This magnetic field is parallel to the first direction a and interacts with the fixed magnetic field of the stator group 6 (six flat stators). The silicon steel sheet group 2 is embedded in the coils 3 as a secondary magnetic circuit carrier, and its silicon steel side plate 202, silicon steel middle plate 203 and flat stator form a closed magnetic circuit. The traveling wave magnetic field induces eddy currents in the silicon steel sheet group 2, but the stacked structure effectively suppresses eddy current losses and improves energy efficiency. The magnetic field interaction generates electromagnetic thrust, which is directed along the first direction a and acts directly on the sliding base 4. The electromagnetic thrust is transmitted to the moving slide rail 503 through the two sliding side rods 401 of the sliding base 4. The sliding base 4 is rigidly connected to the bearing base 1, driving the bearing base 1 and its external load to move linearly along the first direction a. Multiple balls 502 roll in the moving channel, converting sliding friction into rolling friction, supporting the high-speed, high-acceleration movement of the slide table (such as rapid start and stop). Six evenly laid-out flat stators provide a continuous magnetic circuit, reducing thrust fluctuations caused by edge effects and ensuring smooth movement. When the ball bearing 502 is at the end of the moving channel, it is guided by a reverser to turn and enter the return channel. After turning in the return channel, the ball bearing 502 re-enters the moving channel, forming a closed loop. This design overcomes stroke limitations, supporting the slide table to achieve infinite reciprocating motion with a finite track length.

[0033] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
