无速度传感器控制的外转子永磁同步电动机的优化设计
Design Optimization of External Rotor Permanent Magnet Synchronous Machines with Respect to Enhanced INFORM-Capability for Sensorless Control
摘要
机车牵引、启动发电机和直接驱动等诸多应用场合都需要比较大的转矩。本文介绍了外转子永磁同步电动机和无速度传感器控制算法的优点,特别是使用INFORM方法时低速和零速时的性能。因此必须考虑饱和效应,并用于增强INFORM方法的性能。
In many applications like traction,starter generators and direct drives the need for high torque is the basic issue. The paper presents the combination of advantages of external rotor permanent magnet synchronous machines and sensorless control algorithms,especially for low speed and standstill using the INFORM-method. Therefore saliency and saturation effects have to be taken into account and have been enforced for improved INFORM performance.
