Abstract:
A fluid circulating assembly includes an electrical machine having a rotor assembly, a stator assembly, and a housing. The housing includes an annular center section and at least two extension portions extending radially outward from the annular center section of the housing. The fluid circulating assembly also includes a controller assembly coupled to the housing. The said controller assembly is positioned radially outward from the stator assembly and located in at least one of the at least two extension portions.
Abstract:
A client computing device comprising an indicia sensor and a processor coupled to the indicia sensor is described. The processor is configured to receive identification data for an original motor through the indicia sensor, identify a replacement motor based at least in part on the identification data, and identify a local seller of the replacement motor based at least in part on a first location associated with the client computing device and a second location associated with the local seller.
Abstract:
A blower assembly includes a fan including a front plate that defines a fan inlet. The blower assembly also includes an inlet plate positioned adjacent the fan such that the inlet plate and the front plate define a cavity therebetween that extends circumferentially about the fan inlet. A motor is coupled to the fan and to the inlet plate and configured to rotate about the rotational axis. The motor is positioned within the cavity.
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 fluid circulating assembly includes a fan impeller having an inlet ring and a rear plate that define a central chamber. The fluid circulating assembly includes an electrical machine having a rotor assembly, a stator assembly, and a housing. The electrical machine is coupled to the rear plate of the impeller such that the electrical machine is positioned entirely outside the central chamber. The housing includes a plurality of fins on a side of the housing opposite the rear plate. The fins extend axially away from the stator assembly. The assembly includes a duct attached to the housing. The duct covers a portion of the fins and extends radially outward from the housing towards an outer edge of the rear plate. The duct is configured to channel air over the portion of the fins to facilitate cooling the electrical machine.

Abstract:
According to an embodiment of the present invention, a component for an electric machine, for example, an interlocking stator, rotor, armature or exciter, for use in an electric machine prepared by a process is provided. The process by which the component is prepared includes the steps of applying a first material to a first portion of a first surface to form a first stator lamination and applying the first material to a second portion of a first surface, spaced from the first portion, to form a first rotor lamination. The process by which the component is prepared further includes the steps of orienting the grains of the first material, applying a second material to the first portion of the first material, applying a second material to the second portion of the first material, and bonding the second material to the first material.
