Motor, speed and voltage related, torque and current related, rated is the rated output at the rated input, this is nonsense, peak output data relationship may not have specific expression, peak output is the maximum that can be achieved, low speed can not maintain constant power, the motor should follow the power = torque *n/9550 relationship
T is the peak value, which can be reached at low speed, so the power should not be the peak value.Peak power I understand that when output T is the peak, the maximum speed (not the peak speed) reached by the motor is the power.(When t is the peak value, the motor can only reach a certain speed due to the reverse electromotive force). When buy Big Power Motor, the high-power motor shall be started with electromagnetic relay breaker and controlled with low voltage and high voltage.From the safety point of view, the high-power motor cannot be started directly.Because of the high power, it needs a lot of current.Direct start is not safe for the operator.Since the advent of electromagnetic relay, the above problems have been solved.Electromagnetic interrupters can control high voltage with low voltage and high current with small current.So as to achieve safe use of electricity.
