Abstract

The embodiment of the invention provides a driving motor resolver zero position debugging method and device, and solves the problems of complex process, low efficiency, high cost and the like in the prior art during batch driving motor zero position angle adjustment. A PLC control system is designed autonomously, the current resolver angle is displayed in real time, manual adjustment is matched, the real-time angle value is made to be within the set angle range, then resolver is fixed, the motor zero point position requirement can be met, operation is easy and convenient, and the detection speed is high.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automatic control, and in particular to a method and device for debugging the zero position of a drive motor resolver. Background technique [0002] The driving motor is an important core component of the new energy vehicle. The accuracy of the rotor position angle information of the driving motor will directly affect the motor torque, the precision of the speed control and the dynamic performance. [0003] The position angle of the rotor of the drive motor cannot be directly measured. It can be judged by detecting the alternating signal output by the resolver (resolver for short) on the drive motor. The initial angle remains the same. Since the deviation value of the motor and the resolver cannot be determined during the manufacturing and assembly process, it is necessary to use a certain method to detect and adjust the angle of the resolver during the motor production and asse...
