本文介绍了一种用于高速主轴驱动的开关磁阻电动机（SRM）的设计和特性。SRM是高度可行的高速（15000 RPM）主轴驱动器，因为它的简单的转子结构。为了与传统的交流感应电机驱动器兼容，SRM的主要尺寸应与感应电机的尺寸相同，并且应使用通用V/f逆变器驱动器。分析表明，电动机应该有一个正弦电感分布轮廓相对于转子位置，以产生无纹波的转矩时，电动机与通用V/f逆变器操作。介绍了一种基于有限元法的正弦电感开关磁阻电机的设计方法。还解释了，对于电机的指定的主要尺寸，可以适当地设计极弧以产生用于正弦电流驱动的最大转矩。SRM驱动器被发现是更节能的比传统的感应电机驱动器通常用于此应用。令人满意的操作特性的SRM为这种应用程序也被提出。
This paper presents the design and characteristics of a switched reluctance motor (SRM) for high-speed spindle drive applications. The SRM is highly feasible for a high speed (15000 RPM) spindle drive because of its simple rotor construction. For compatibility with conventional AC induction motor drives, the main dimensions of the SRM should be identical with those of the induction motor and a general purpose V/f inverter drive should be used. The analysis shows that the motor should have a sinusoidal inductance distribution profile with respect to the rotor position in order to produce a ripple-free torque when the motor is operated with a general purpose V/f inverter. The FEM-based design procedure of an SRM with a sinusoidal inductance distribution is described in the paper. It is also explained that, for specified main dimensions of the motor, the pole arc can be designed suitably to produce maximum torque for a sinusiodal current drive. The SRM drive is found to be more energy efficient than conventional induction motor drives normally used for this application. Satisfactory operating characteristics of the SRM for this application are also presented.
