The rated current is not the maximum current during the operation of the motor.
Rated current refers to the current value of the motor when running under rated voltage and rated power, which is the normal working current specified in the design and manufacture of the motor. The motor can run statically for a long time at rated current, and can ensure that its performance and life meet the design requirements.
The maximum current during the operation of the motor may exceed the rated current, for example, at the start of the motor, because the rotor has not reached the rated speed, the back electromotive force is small, which will lead to a large starting current, usually up to several times the rated current; Or when the motor is overloaded, blocked and other abnormal conditions, the current will also increase sharply, exceeding the rated current, at this time the motor may be damaged, and even cause safety accidents.
