Description

technical field [0001] The invention belongs to the technical field of aerospace servo, and in particular relates to an integrated dual-channel control driver for a permanent magnet synchronous servo motor. Background technique [0002] With the development of magnetic materials, power electronic devices and digital processor technology, the combination of high-performance motors and modern control technology has led to the rapid rise of electromechanical servo technology. Electromechanical servo systems are used more and more widely, and at the same time, the requirements for their integration and reliability are getting higher and higher. [0003] Most of the control drives for permanent magnet synchronous motors above 5 kW class designed in the past are single-channel, and there are no redundant measures for the main circuit. Once a failure occurs, the electromechanical servo system will not work normally. [0004] The integrated dual-channel control driver in this desig...
