Problems solved by technology

[0002] In the existing ratchet motor, the ratchet is on the inner side of the pole plate and the magnetic steel is a ring magnet. The length of the ring magnet is long, so the inertia of the rotor is large and the signal response speed is slow; and the existing ratchet motor When working, the two-phase coils are energized separately, and only half of the magnetic steel is outputting power at the same time, so the magnetic utilization rate is low and the working efficiency of the motor is low.

Embodiment Construction

[0020] Such as Figure 1-3 As shown, a claw ratchet disc stepping motor includes a housing 1, and the two ends of the housing 1 are respectively connected to the shaft rods 31 on both sides of the rotor 3 through bearings 2; the outer periphery of the rotor 3 is a disc magnetic steel 4. Both sides of the rotor 3 are provided with pole plate assemblies 5, and each of the pole plate assemblies 5 is provided with a pawl structure on the end face facing the disc magnet 4, and each of the pole plate assemblies 5 is internally set There is a skeleton 53, a coil 54 is wound on the skeleton 53, a positioning ring 6 is arranged on the outer peripheral side of the disc magnet 4 and between the two pole plate assemblies 5, and the positioning ring 6 is used to separate two groups Pole plate combination 5, reserves the space that disk type magnetic steel 4 rotates. The two coils 54 are set to be energized at the same time, and the direction of the current is alternately changed.

Abstract

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.

Description

technical field [0001] The invention belongs to the related technical field of stepping motors, and in particular relates to a pawl ratchet disc type stepping motor. Background technique [0002] In the existing ratchet motor, the ratchet is on the inner side of the pole plate and the magnetic steel is a ring magnet. The length of the ring magnet is long, so the inertia of the rotor is large and the signal response speed is slow; and the existing ratchet motor When working, the two-phase coils are energized separately, and only half of the magnetic steel is outputting power at the same time, so the magnetic utilization rate is low and the working efficiency of the motor is low. Contents of the invention [0003] The purpose of the present invention is to provide a pawl ratchet disc stepping motor to solve the problems raised in the above-mentioned background technology. The entire disk-type magnetic steel outputs power, which improves the magnetic utilization rate and the...
