【Abstract】 This passage puts forward an indirect speed test method of the separately excited motor,which can calculate the motor speed quickly by controlling the parameters of main current,armature current and exciting current of the motor.So it can solve the speed test question of the separately excited motor,when the motor has no speed sensor.This method is not only simple,but also easy to achieve.And the experimental data and results are presented.更多还原
