Gearless permanent magnet synchronous traction motors (PMSM) offer lower life cycle costs compared to induction motors with gear units; however, PMSM usually require one inverter per motor. In commuter trains, one inverter feeds up to four induction motors – a cost advantage for induction motor drives. The feasibility of a group drive with two PMSM fed by one inverter is investigated to limit the number of inverters.
