摘要： An electric machine assembly having an electric machine. The electric machine can include a first speed circuit and a second speed circuit. In some constructions, both speed circuits can be of a permanent split capacitor design. At least one of the speed circuits can include a switch that is controlled by the controller to limit current through an auxiliary circuit of the unused speed circuit when certain conditions exist.

摘要： An electric motor including having a housing, a stator fixed relative to the housing, a shaft rotatable about a motor axis, a rotor supported by the shaft for rotation with the shaft relative to the stator, a terminal board fixed relative to the housing, and first and second electrical terminals supported by the terminal board. The electric motor also includes an operating condition selection device including a moveable portion supported by the terminal board for pivotable rotation about a second axis between a first position corresponding to a first operating condition and a second position corresponding to a second operating condition. At least a portion of the moveable portion substantially remains in a fixed axial position relative to the second axis while pivoting between the first and second positions. The electrical terminals are accessible through a conduit receiving aperture for testing purposes.

摘要： An electric motor selectively connectable to receive one of a plurality of supply voltages, the plurality of supply voltages comprising a low supply voltage and a high supply voltage. The motor can comprise a stator having a first winding and a second winding, a shaft rotatable about a motor axis, and a rotor supported by the shaft for rotation with the shaft relative to the stator. The motor can also comprise a voltage selection device, a first motor protector, and a second motor protector. The voltage selection device can include a first setting and a second setting and can be configured to connect the first winding in parallel with the second winding when set to the first setting and to connect the first winding in series with the second winding when set to the second setting. The first motor protector can be configured to limit current through the first winding and the second winding when an overload condition exists. The second motor protector can be configured to limit current through the first winding and the second winding when the voltage selection device is set to the first setting and the electric motor is connected to a high supply voltage.
摘要翻译：电动机可选择性地连接以接收多个电源电压中的一个，所述多个电源电压包括低电源电压和高电源电压。电动机可以包括具有第一绕组和第二绕组的定子，可围绕电动机轴线旋转的轴和由轴支撑的用于与轴相对于定子一起旋转的转子。电动机还可以包括电压选择装置，第一电动机保护器和第二电动机保护器。电压选择装置可以包括第一设置和第二设置，并且可以被配置为当设置为第一设置时将第一绕组与第二绕组并联连接，并且当设置为第一组合时将第一绕组与第二绕组串联连接第二个设置。当存在过载条件时，第一个电机保护器可以配置为限制通过第一个绕组和第二个绕组的电流。第二电动机保护器可以被配置为当电压选择装置被设置为第一设置并且电动机连接到高电源电压时，限制通过第一绕组和第二绕组的电流。
