heal.abstract	The authors investigate and analyse the electric power operating conditions of podded electric motor drives, mainly in an attempt to explain the high failure rates of the electric components in pod propulsion installations. The analysis is based on simulations, where the pod torque demands are obtained from experimental results recently published in the literature. Thus, the same series of loading scenarios for an entire range of turning azimuth angles of a twin pod configuration are considered. The approach is rather generic as only nameplate data of the motor drives are required while, as the simulations focus on the electric motors, the rest of the ship electric system considered, including generator sets, is represented by a simplified network. Two different sets of simulations are considered, one comprisng a synchronous ac motor drive and one with an asynchronous motor motor of similar rating. In all cases, it is shown that during manoeuvring in a certain range of azimuth angles significant overloading occurs exceeding the apparent power capacity of the motors.	en
