Motor selection for asynchronous motors
In this case, the mechanical resistance of the motor against the overload, which might exceed the permitted threshold values, must always be checked.
Mpk and npk depend on the motor/inverter combination, as well as on the used control mode.
Asynchronous motors are mainly operated in VFCPLUS control mode. The control mode efficiently adjusts the motor magnetization to the respective operating point. It simultaneously enables dynamic responses to load shocks on the drive train.
