Abstract :
This paper concentrates on the input impedance of a low voltage electric motor at high signal frequencies. A series of impedance measurements is carried out for a group of induction motors. The measurements are analyzed and a simple measurement based model for the input impedance of the electric motor is formed. In addition, the effect of the rotor on the input impedance is researched. Finally, the effect of impedance mismatch at the interface of the motor and the cable is briefly analyzed.
