(1) make sure electromotor moving environment is favorable (2) make sure electromotor temperature rise does not exceed a level

(3) change the electromotor with big loss

(4) the starting number that limits electromotor

(5) the empty running that decrease or eliminates electromotor

(6) execute static capacitance to wait for measure without result power compensation to three-phase asynchronous electromotor (electric inspect can be offerred)
