| 摘 要： | 城轨车辆的牵引电机在牵引和电制动工况下短时过载可达50%,瞬时过载可达100%.IGBT牵引逆变器在电制动时浪涌输出电流尖峰值允许超过器件额定电流20%.并联工作电机负荷不平衡受轮径差影响极大,与电机转差率相关.提出了逆变器与牵引电机的配置原则.

| Abstract: | The short-time overload of traction motors of urban vehicles in traction and electric braking can reach 50% while the transient overload can reach 100%. The peak value of surge output current allows going beyond the rated current of devices 20%.The unbalanced load of parallel motors are large influenced by wheel radius deviation and are relative to motor slip deviation. It is presented the match principle of inverter and traction motor. |
