Abstract

The invention belongs to the field of control systems, and particularly relates to a wide-rotation-angle limited-rotation-angle servo motor. The motor comprises a stator, a rotor, an end cover assembly I, an end cover II, an elastic check ring and a wave spring, the end cover I is positioned on the left side of the stator and is in transition fit with a shell of the stator; the end cover II and the end cover assembly I are fixed by an elastic check ring; a bearing at the output end of the rotor is positioned in a bearing chamber of the stator; a bearing at the non-output end of the rotor is positioned in a bearing chamber of the end cover II; the wave spring is located in a bearing chamber of the end cover II to apply a pre-tightening force to the bearing at the non-output end of the rotor, and a gap, namely an air gap, exists between the stator and the rotor. The limited rotation angle servo motor is simple in structure, high in torque density, wide in working rotation angle and highin positioning precision.

Description

technical field [0001] The invention belongs to the field of control systems, and in particular relates to a servo motor with wide rotation angle and limited rotation angle. Background technique [0002] The limited rotation angle servo motor is a single-phase brushless servo motor in which the rotor can directly drive the load within a certain angle range for fast movement and accurate positioning when the stator winding is supplied with direct current. The position servo system composed of this motor has the characteristics of large output, wide frequency band, high positioning accuracy, small size and light weight. It can be used in high-precision electrical servo systems such as aviation servo valves, steering gear actuation, robot joints, and radar antennas to directly drive loads within a limited angle, without additional transmission devices, and has high system accuracy and reliability. [0003] The limited rotation angle motor can be divided into two structures: sl...
