A method for selectively operating an electric motor in one of a first pole configuration and a second pole configuration is provided. The first pole configuration has a first phase winding structure, a second phase winding structure and a third phase winding structure. The method includes energizing each of the first phase winding structure, the second phase winding structure and the third phase winding structure to operate the electric motor in the first pole configuration. The first phase winding structure is reconfigured to form a first phase, a second phase and a third phase of the second pole configuration. The first phase winding structure is energized and each of the second phase winding structure and the third phase winding structure is de-energized to operate the electric motor in the second pole configuration.

Method and system for selectively operating an electric motor

A method of making a leakage flux conducting device and securing it to a non-ferrous end plate of a prime mover. In this method, the device is formed with a mass great enough so that it remains unsaturated with respect to the leakage flux carried thereby, and the device is provided with a plurality of means arranged for deformation into engagement with associated parts of the end plate. The device is moved into an assembly position on the end plate, and the deformation means are deformed into engagement with the associated parts of the end plate thereby to prevent displacement of the device from its assembly position on the end plate.

Method of making and securing a leakage flux conducting device

A prime mover has a non-ferrous end plate with a leakage flux conducting device disposed in a preselected assembly position thereon. The device conducts across the end plate leakage flux emanating from a magnetic field established between a pair of opposite pole winding means of the prime mover upon the energization thereof. Fingers integral with the device are provided for securing it in the preselected assembly position thereof on the end plate.
