In conclusion, disc-type magnetic steel is arranged on the periphery of a rotor, and a claw ratchet structure is arranged on the end face, right facing the disc-type magnetic steel, of the polar plate combination in cooperation with the structure of the disc-type magnetic steel, so that the structural design solves the problems that an existing claw ratchet is arranged on the inner side of a polar plate, the magnetic steel is annular magnetic steel, and the annular magnetic steel is long in length, so that the inertia is large and the signal response speed of the rotor is slow. The disc type magnetic steel provided by the invention has the advantages that the inertia is small, the technical effect of improving the signal response speed is achieved, and the working efficiency of the motor is improved. Through the structural design, the two coils can be arranged to be electrified at the same time, the problems that when an existing claw-ratchet type motor works, the two phases of coils are electrified separately, only half magnetic steel outputs power at the same time, and the magnetic utilization rate is low are solved, the whole disc type magnetic steel can output power at the same time, the technical effect of improving the magnetic utilization rate is achieved, and the working efficiency of the motor is further improved.

Example Embodiment

[0020] like Figure 1-3 As shown, a claw step-axis step motor comprising a housing 1, and the outer end of the outer casing 1 is rotated through the bearing 2 on both sides of the rotor 3; the outer circumference of the rotor 3 is a disc magnetic steel. 4. Both sides of the rotor 3 are provided with a polar plate combination 5, each of which is positive on the end face of the disc magnetic steel 4, and each of the polar plate combination 5 is disposed. There is a skeleton 53, and the skeleton 53 is provided with a coil 54, the outer peripheral side of the disk magnetic steel 4, and two polar plate combinations 5 are provided with a positioning ring 6, and the positioning ring 6 is used to separate the two groups. Polar combination 5, leaving the space of the disc magnetic steel 4 rotation. The two coils 54 are set to energize simultaneously, alternately change the current direction.
[0021] The plate combination 5 includes an outer electrode plate 51, an inner plate 52, and the outer polar plate 51 and the inner plate 52 are positive on the end face of the disc magnetic steel 4, and the skeleton 53 is disposed. The outer pole plate 51 and the inner portion constituted by the inner plate 52. The claw structure of the outer polar plate 51 and the claw structure of the inner electrode plate 52 are arranged to be mutually to each other.
[0022] The outer casing 1 includes a cover plate 12 and a housing cover 11 having a bearing 2 at the center of the cover plate 12 and the outer casing 11.
[0023] like image 3 As shown, the coil 54 is energized to generate a loop magnetic field, and the magnetic line is entered into the cover 12 by the skeleton 53, and then the lid 12 enters the inner electrode plate 52, and magnetic the inner polar plate 52, the outer electrode plate 51 forms magnetic potential, The inner plate 52, the outer electrode plate 51 exhibits different poles such as Figure 4 Indicated.
[0024] like Figure 5 As shown, the disc magnetic steel 4 is magnetically magnetically angled, and the number of magnetic poles must be an integer multiple of 2. Figure 5 The second6 magnetic pole, at which time the inner plate 52, the number of pawls 51 is 1/2 times of the number of magnetic poles, respectively; the number of magnetic poles can be designed according to the need, the pawl on the plate The magnetic pole logs on the disc magnetic steel 4 correspond. The plates of the two coils 54 must also be displaced a 1/2 polar distance.
[0025] The operation principle of the present invention is as follows: the two coils 54 are energized to form the magnetic field generated by the two sets of end plates 52, the outer only plate 51 and the disk magnet 4. Figure 6-1 The balance position shown; when the current is changed in one of the coils 54, the magnetic field generated by the coil 54, the magnetic field generated by the magnetic field generated by the outer electrode plate 51, Figure 6-2 As shown, if the disc magnetic steel 4 is in Figure 6-1 If the location, an anisotropic magnetic field and an identity magnetic field are attracted to an exclusion. At this time, the disk magnetic steel 4 will be pulled by the magnetic field to new. Figure 6-2 The balanced position shown, and the moving direction is unique; the same as the current in the two coils 54 is pressed Figure 6-1 , Figure 6-2 , Figure 6-3 , Figure 6-4 The order in which the sequence is changed and the circulation is formed, and the disc magnetic steel 4 will drive the rotor 3 to rotate and turn to the unique. The present invention enhances the magnetic field generated by the power-on coil 54 by a plate, and utilizes the claw effect to produce a high-density magnetic energy N-pole or the Node or S pole, and the polarity varies with the current direction, so the disk The magnetic steel 4 is displaced under the traction of the alternating magnetic field.
[0026] In summary, the present invention is provided to form a claw spine structure on the end surface of the plate magnets in the outer circumference of the rotor, and the structural design is set up on the end face of the disk magnetic steel in the outer circumference of the rotor. The claws are in the inner side of the polar plate and the magnetic steel is a ring magnetic steel, and the length of the ring magnet is long, the inertia of the rotor is large, the signal response speed is slow, and the disc magnetic steel of the present invention is small, and the signal is improved. The technical effect of the response speed improves the operating efficiency of the motor. The present invention also passes through the above-described structural design, so that two coils can be provided to energize simultaneously, solve existing claws, and the two-phase coil is turned on, and only half of the magnetic steel in the same time is output power, resulting in magnetic utilization. The problem of low rate, the present invention can output power throughout the disc magnetic steel, reaching the technical effect of improving the magnetic utilization, further improving the operating efficiency of the motor.
