Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to a motor driver. Background Art

[0002] Motor drivers are usually used as driving devices in industrial automation equipment. Motor drivers are controllers used to control motors. The motor driver compares the feedback value of the motor's built-in encoder with the target value to adjust the rotation angle and speed of the motor rotor.
