The double-closed-loop structure comprises a motor shaft, a brake rotor, a guide key, a brake stator, a brake stator mounting base, a bearing end cover, a rotary transformer stator, a rotary transformer rotor and an angular contact ball bearing;the rotary transformer rotor is wrapped on the outer wall of the output end of the motor shaft; the rotary transformer stator is wrapped on the outer wall of the rotary transformer rotor; the bearingend cover is fixedly arranged on the outer wall of the rotary transformer stator; the angular contact ball bearing is fixedly arranged on the outer wall of the motor shaft; the brake rotor is fixedlyarranged at one end of the angular contact ball bearing; the brake stator is fixedly arranged on the outer wall of the brake rotor; the brake stator mounting base is arranged on the outer wall of thebrake stator in a sleeved mode; and the guide key is fixedly arranged on the outer wall of the brake stator mounting base. The double-closed-loop structure is used for realizing the installation of abrake and a rotary transformer, and can bear bidirectional axial force.

Description

technical field [0001] The invention relates to the field of electromechanical actuators, in particular to a double closed-loop structure suitable for movable outer rotor motors. Background technique [0002] The movable outer rotor motor is a transmission form of the double-redundant electromechanical actuator, with the inner rotor motor as the main working part and the outer rotor part as the backup. When the inner rotor motor or actuator fails, the outer rotor motor outputs linear motion through overall translation to provide thrust to the output end. The brake is the locking device of the dual-redundancy electromechanical actuator, which is used to control the rotational movement of the motor. The resolver is a motor speed sensor, which is used to feed back the motor speed signal. [0003] Since the stator of the outer rotor motor is on the inside and the rotor is on the outside, it is difficult to install the brake and the resolver. [0004] The combined installation...

AI Technical Summary

Problems solved by technology

[0003] For external rotor motors, since the stator is on the inside and the rotor is on the outside, it is difficult to install the brake and resolver

[0004] The combined installation of the movable brake and the rotary transformer is not involved in the existing structural design, which cannot meet the signal acquisition and redundancy switching function requirements of the inner and outer rotor motors with dual redundancy functions
