    • A variable speed motor includes first and second main windings wound on a stator, and a relay for performing a switching operation between serial/parallel connections of the first and second main windings to control motor speed. The variable speed motor further includes a tap winding connected in series to the main windings, or an additional capacitor, such that it can greatly extend the range of a variable speed without using a drive unit capable of changing the motor speed at an external location, resulting in reduced production costs of the motor, reduced electromagnetic vibration noise, and reduced power consumption.
    • 变速电动机包括缠绕在定子上的第一和第二主绕组以及用于在第一和第二主绕组的串联/并联连接之间执行开关操作以控制电动机速度的继电器。 变速电动机还包括与主绕组串联连接的抽头绕组或附加电容器,使得其可以在不使用能够改变外部位置处的电动机速度的驱动单元的情况下大大地扩展可变速度的范围, 导致电机的生产成本降低,电磁振动噪声降低,功耗降低。
