摘要： A permanent magnet synchronous motor includes a shaft with an integrally formed flange and resolver rotor. The resolver rotor is formed by machining a set of cutouts in the flange. The rotor body, which includes the permanent magnets, is assembled onto the shaft from the end of the shaft opposite the flange and resolver rotor. Features, such as keyways on the shaft and keys on the rotor body establish a rotational position relationship between the shaft and the permanent magnets.

摘要： A rotor assembly includes a plurality of laminations stacked to form a rotor core that defines a plurality of pockets and coolant passageways, a plurality of magnets disposed within the pockets, and a molded cage. The molded cage includes a plurality of columns securing the magnets within the pockets, and a pair of endcaps covering portions of the pockets on opposite ends of the rotor core such that the endcaps are connected with the columns. The endcaps define a plurality of apertures in fluid communication with the coolant passageways.

摘要： A rotor includes a plurality of rotor cores arranged in a vertical stack, an end plate having a specified roughness on a surface engaging the vertical stack, and a binder material bonding the end plate to the vertical stack of rotor cores. The specified roughness is configured to allow venting of air beyond the end plate and to prevent passage of resin beyond the end plate.

摘要： A skewed rotor core assembly having a resin mold disposed in a plurality of longitudinal channels and a resin flow path is provided. The rotor core has a first and second magnet stack each defining a plurality of longitudinal channels. The plurality of longitudinal channels for the first stack are misaligned with the plurality of longitudinal channels for the second stack. Methods of making the same are also provided.
