Description

Technical Field

[0001] This utility model relates to the field of rotor commutator angle detection technology, and in particular to a tooling for detecting the angle of a motor rotor commutator. Background Technology

[0002] A commutator angle of 0° with the core angle of the motor can ensure that the current is reduced and the speed is increased during motor operation, thereby increasing the efficiency of the motor. Therefore, the deviation range between the commutator angle and the core angle must be precisely controlled. Traditional commutator angle detection is carried out by projection detection using two-dimensional or three-dimensional methods, which is cumbersome and inefficient. In view of the above defects, this application is proposed. Utility Model Content
