Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, a high-stability permanent magnet torque device includes a rotor 1, such as figure 2 As shown, the lead wire 2 and the stator, such as image 3 As shown, the stator includes a magnetic spacer 3, a gasket 4, an outer magnetic ring 5, a permanent magnet 6, a magnetic steel seat 7, an inner magnetic ring 8, and a stator seat 9;

[0024] The magnetic steel base 7 is a hollow cylinder, and the wall of the hollow cylinder is provided with eight rectangular through holes. A piece of permanent magnet steel 6 is embedded in eight rectangular through holes on the wall of the magnet steel seat. It is flush with the outer surface; the gasket 3 is a ring, and the magnetic isolation sheet 3 is a hollow annular sheet. A hollow ring-shaped liner 4 matching the size of the magnetic spacer 3, the lower surface of ...

Abstract

The invention relates to a high-stability permanent magnet torque device, which belongs to the field of electromagnetic components. The torque device includes: shell, permanent magnet steel, coil and skeleton, etc. The torque device of the present invention uses permanent magnetic steel as the excitation magnetic field source, and the coil rotates in the magnetic field after being energized. High linearity and stability; the sensitivity of the torque device is high; the rotor is output through soft wires, and the disturbance torque is very small.

Description

technical field [0001] The invention relates to a high-stability permanent magnet torque device. The torque device uses permanent magnet steel as the excitation magnetic field source. After the coil is energized, it is forced to move in the magnetic field. The torque output in the uniform range has nothing to do with the position of the rotor, and has high linearity and stability; the torque sensor has high sensitivity; the rotor outputs through soft wires, and the interference torque is very small. The torque device belongs to the technical field of electromagnetic components. Background technique [0002] The torque coefficient of the existing permanent magnet torque device is poor in stability and varies greatly with temperature, which affects the accuracy of the instrument. Therefore, it is necessary to design a new permanent magnet torque device, improve the torque coefficient stability of the torque device, reduce the torque device's interference torque, so that the a...
