Abstract

A linear analysis is used to compare the static torque produced by a mutually coupled variable reluctance motor to that produced by a conventional SRM (switched reluctance motor). A similar analysis has also been completed to compare the static torque of a variable reluctance motor with anisotropic rotor to that produced by an SRM. The motors were compared on the basis of fixed source voltage and current. It is shown that for motors with a similar number of poles and phases, the maximum improvement in static torque of the mutually coupled motor over that of the SRM is 200% while the maximum improvement in static torque of the anisotropic motor is 222% over that of the SRM. However, end turn length differences and saturation tend to reduce the benefits from these designs. Effects associated with end turn length due to aspect ratio pole, and phase combinations have also been studied. It is shown that the greatest benefit from the alternative variable reluctance structures occurs for low diameter to length ratio and a small number of poles and phases.<>

用于低速运行的可变磁阻电机结构

用线性分析方法比较了相互耦合的可变磁阻电机与传统开关磁阻电机产生的静态转矩。将各向异性转子的变磁阻电机与SRM产生的静转矩进行了类似的分析比较。在固定电源电压和电流的基础上，对两种电机进行了比较。结果表明，在极数和相数相同的情况下，互耦电机的静转矩比SRM的最大提高200%，各向异性电机的静转矩比SRM的最大提高222%。然而，端匝长度差异和饱和往往会减少这些设计的好处。此外，还研究了长径比、极性和相位组合对端匝长度的影响。结果表明，可变磁阻结构的最大优点是直径长比低，极相数量少。
