An electric machine is provided. The electric machine includes a stator and a rotor. The rotor is rotatably secured to the stator. The electric machine further includes a shaft secured to the rotor and a sleeve. The sleeve defines a bore and an outer periphery of the sleeve. The sleeve is slidably secured to the shaft. The electric machine further includes a bearing defining a bore of the bearing. At least a portion of the bore of bearing is fixedly secured to at least a portion of the outer periphery of the sleeve.

Electric machine, assembly and associated method

In one aspect, a stator for use in a liquid cooled electric machine having a rotor is provided. The stator includes a stator body having a radially outer periphery and a radially inner periphery, and at least one first coolant passage extending radially through the stator body from the outer periphery to the inner periphery. The at least one first coolant passage facilitates providing a coolant to an air gap defined between the stator body and the rotor.

Electric machine with liquid cooling and method of assembling

A bearing assembly for an electric motor is provided that includes a bearing having an inner race and an outer race, and a bearing float sleeve having an outer race engaging member. The outer race engaging member includes an outer surface sized for slip fit engagement with a bearing seat formed in a motor end member such that the bearing float sleeve can be displaced axially in relation to the bearing seat and an inner surface configured for engagement with the bearing outer race such that the bearing outer race is in a fixed rotational position with respect to the bearing float sleeve. The bearing float sleeve includes at least one feature operational to maintain a fixed rotational position of the bearing float sleeve with respect to the motor end member.
