摘要
无齿轮传动的永磁同步牵引电动机(PMSM)的寿命周期费用低于有齿轮传动装置的感应电动机。然而,通常一台PMSM电机需要一台逆变器。而在市郊列车上,一台逆变器最多可向4台感应电动机供电——这是感应电动机驱动的一个费用低的优势。作为减少逆变器数量的研究,文章探讨了一台逆变器供电给两台PMSM成组传动来减少逆变器数量的可行性。
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.
