    摘要:

    针对低地板有轨电车用传统牵引电机布置不便、传动效率低等现状,提出一种盘式永磁电机直驱独立车轮方案.电机整体悬挂于构架外侧,使得电机质量为簧上质量.由尺寸方程估计电机基本尺寸后,再使用编写的电机CAD(Computer aided Design)程序设计60 kW电机以满足有轨电车牵引需求.采用基于滑模观测器的无位置传感器矢量控制方式对电机进行牵引控制.根据车辆导向控制特点,分别对转向架同侧电机和两侧电机进行差速控制.在MATLAB/Simulink平台下搭建电机控制模型,仿真结果表明,电机控制响应快、鲁棒性高;多个电机协调导向性能好,适应直道和弯道线路的控制需求.

    Abstract:

    To overcome the disadvantages of conventional motor in low floor tramcar with difficult installation arrangement and low transmission efficiency, a new solution was proposed with disc permanent magnet synchronous motor(PMSM) direct drive and independent rotating wheels. The disc PMSM was overhung in the bogie frame with elastic suspension, which made them as the sprung mass. A 60kW disc PMSM was designed under developed motor Computer aided Design(CAD) program to meet the traction power demand, after estimating the overall dimensions according to the size equation of motor. Sensorless vector control based on the sliding mode observer(SMO) was adopted in speed control and torque control of PMSM. The same side and both side motors will control speed difference under the steering control strategy of tramcar. Finally, motor control model was set up in MATLAB/Simulink to check the control strategy. The simulation results show that the PMSM control based on SMO has rapid and robust response. Multi motors with good steering performance adapt to the the straight or curve track well.
