Abstract

The invention belongs to a motor drive controller, and particularly discloses a tri-redundancy brushless DC servo drive controller which comprises three servo control driver circuits, wherein the servo control driver circuits are connected in parallel, are respectively communicated with a brushless DC motor, and communicate with one another; each servo control driver circuit comprises a servo control module, a motor driver module, a current detection module and a potentiometer; the output end of each servo control module is communicated with the input end of the corresponding motor driver module; the output end of each motor driver module is communicated with a three-phase winding output end of the brushless DC motor; the input end of each current detection module is communicated with a detection signal output end of the brushless DC motor; the output end of each current detection module is communicated with the input end of the corresponding servo control module; the input end of each potentiometer is communicated with a position signal output end of the brushless DC motor; the output end of each potentiometer is communicated with the digital signal input end of the corresponding servo control module. Through the adoption of the tri-redundancy brushless DC servo drive controller, high integration and redundancy design of electromechanical servo control can be realized.

Description

technical field [0001] The invention belongs to a motor control driver, in particular to a drive controller of a kilowatt-level triple redundant electromechanical servo mechanism. Background technique [0002] As an important part of the electromechanical servo mechanism, the motor control driver directly drives the servo motor, drives the servo actuator, and converts electrical energy into mechanical energy. At present, the launch vehicle has successfully adopted and promoted redundant electro-hydraulic servo mechanism technology to improve the reliability of the system. The application of electromechanical servo mechanism to aircraft also needs to solve the reliability problem. Existing electromechanical servo mechanism control drivers usually use dual-redundancy double-winding electromechanical servo control drivers, and their power levels and redundancy are low. It cannot meet the high reliability requirements of new aircrafts. Contents of the invention [0003] The...
