Flat limited angle torque motor

Abstract

The invention relates to a flat limited angle torque motor, which comprises a gland, a case, a motor shaft, a bearing I, a bearing II, a magnetic steel base I, a magnetic steel base II, magnetic steelI, magnetic steel II, magnetic steel III, magnetic steel IV, a rotor skeleton, a coil I and a coil II, wherein the gland is arranged on the case; an installation hole is formed in the middle of eachof the gland and the case; the motor shaft is arranged in the gland and the case to form a shaft of the motor; the magnetic steel I and the magnetic steel II are arranged on the magnetic steel base I;the magnetic steel III and the magnetic steel IV are arranged on the magnetic steel base II; the magnetic steel base I and the magnetic steel base II are fixed on the inner side wall of the gland through bolts to form a stator of the motor; the coil I and the coil II are fixed on the rotor skeleton; and a hole is formed in the middle of the rotor skeleton and fixed to the motor shaft in a matchedmanner to form a rotor of the motor. The flat limited angle torque motor provided by the invention has the advantages of being very small in axial size, high in volume utilization rate and light in weight and is very suitable for application in a lightweight system.

Description

technical field [0001] The invention relates to a limited-rotation-angle motor in the technical field of driving, in particular to a flat-type limited-rotation-angle torque motor. Background technique [0002] As an actuator, the motor is widely used in automatic control systems. In some precision servo drive fields, the motor does not need to run continuously within 360°, and the output torque requirement of the motor is relatively low, but the volume requirement of the motor is very strict, especially the axial size, such as the UAV pod system . [0003] Based on its basic electromagnetic principle, the traditional finite-angle motor is generally made into a cylindrical structure, which has the problems of large volume, heavy weight, and low space utilization. The motor with cylindrical structure must occupy part of the axial space at the end of the winding, so the axial dimension cannot be compressed very small. With the miniaturization and lightweight development of t...
