Can a non-inverter duty rated motor be used if load reactor or dV/dT filter is installed?
Due to wide variations in non-inverter duty rated motors, it can’t be stated that a line reactor or dV/dT filter will fully protect the motor. It’s suggested that as a minimum, a dV/dT filter should be used.
A full sine save filter may be needed to fully protect non-inverter duty rated motors.
