A blower includes an impeller housing, an impeller rotatably secured to the housing and an electric motor. The motor has a motor housing with a central portion and a radially extending portion extending from the central portion, a venturi chamber adjacent the motor housing and opposed to the impeller housing, a stator secured to the central portion of the motor housing, a rotor rotatably secured to the central portion of the housing, and at least one heat generating electrical component secured to the radially extending portion of the motor housing. The impeller housing has a first air pressure therein and the motor housing has a second air pressure therein different that the first air pressure. The venturi housing and the motor housing define a passageway therebetween whereby the difference in air pressure generates air flow within the motor housing to cool the at least one heat generating electrical component.

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.
