Abstract: 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.

Abstract: A motor assembly includes an electric motor having a stator and a rotor. A housing is coupled to the electric motor. The housing includes a terminal housing portion defining a first aperture and a second aperture. A power input terminal is disposed within the terminal housing portion. The power input terminal receives power input connections from at least one of the first aperture and the second aperture. A motor controller is disposed within the housing, the motor controller in communication with the power input terminals and the stator. A human machine interface (HMI) is in communication with the motor controller.

Abstract: A motor assembly includes an electric motor having a stator and a rotor. A housing is coupled to the electric motor. A motor controller is disposed within the housing. A human machine interface (HMI) is selectively detachably coupled to the housing and in communication with the motor controller. The HMI includes a user input for control of the electric motor when the HMI is coupled to the housing and for control of the electric motor when the HMI is separately disposed from the housing.
