Abstract:
A motor controller for a motor is described. The motor controller includes a communication device coupled to a memory device. The motor controller is configured to receive, using the communication device, a status query from a client computing device. The motor controller is additionally configured to transmit diagnostic data from the memory device to the client computing device, transmit identification data associated with the motor controller to the client computing device, receive, from the client computing device, a decommission password generated from the identification data, and disable the motor using the decommission password.
Abstract:
A grounding device for an electric machine, having a rotating component and a stationary component, includes a core fabricated from a non-conductive material and a plurality of conductive fibers coupled to the core and extending therefrom. The plurality of conductive fibers are configured to electrically couple the rotating component with the stationary component such that an electrostatic charge on the rotating component is directed through the plurality of conductive fibers to the stationary component.
Abstract:
An air transferring system is disclosed. The air transferring system includes an enclosure, a faceplate, and a blower assembly attached to the faceplate. The enclosure includes a base, a lid having an air exhaust, and a shroud. The shroud has an open shroud top, an open shroud bottom, and an opening in the shroud defined between a first shroud edge and a second shroud edge. Each of the shroud edges extends between the open shroud top and the shroud bottom. The faceplate includes a faceplate opening that extends between the first and second shroud edges. The blower assembly includes a blower exhaust proximate to all of the faceplate opening, an exhaust opening, and an impeller for drawing air through the air exhaust, faceplate opening, and blower exhaust and urging the air out the exhaust.

Abstract:
A housing for an electrical machine includes an endshield and a cover. The electrical machine has a rotation axis, a rotor assembly including a rotor, and a controller assembly. The rotor assembly includes a bearing assembly. The endshield includes an annular center section including a bore sized to couple to the bearing assembly. The cover is coupled to the endshield. The cover includes a generally axially-extending flange wall formed about a perimeter of the cover, a volute-shaped inner chamber configured to at least partially enclose the rotor coupled to the rotor assembly of the electrical machine, and a cooling channel positioned radially outward from the inner chamber. The cooling channel is configured to at least partially enclose the controller assembly of the electrical machine.
