Abstract: A motor drive controller is provided that includes a current source inverter. The current source inverter includes driver circuitry configured to generate switching commands; a variable current source configured to generate a variable current that regulates power in a motor; and motor commutation circuitry configured to receive the variable current and switching commands, and to commutate phase currents that are output to the motor.

Abstract: A low-voltage motor is provided that includes a rotor and a stator having two or more phase windings and a number of single-turn coils. Each phase winding comprises a plurality of the single-turn coils connected together. Each of the single-turn coils is a single conductive loop that includes only one conductor on each side of the single-turn coil.

Abstract: Embodiments of the present disclosure relate to an electric motor drive system for driving a low-voltage motor. The low-voltage motor includes a rotor and a stator that comprises a number of single-turn coils. A motor drive controller can control the low-voltage motor. The motor drive controller includes a current source inverter. The current source inverter includes driver circuitry configured to generate switching commands, a variable current source and motor commutation circuitry. The variable current source can generate a variable current that regulates power in the low-voltage motor. The motor commutation circuitry receives the variable current and switching commands, and commutates phase currents that are output to the low-voltage motor.

Abstract: Embodiments of the present disclosure relate to a low-voltage motor. The low-voltage motor includes a housing, a rotor disposed within the stator, and a stator disposed within the housing. The stator includes a first circuit board; and a second circuit board, and a number of single-turn coils. The first circuit board and the second circuit board each have a number of plated through-openings and wirings formed therein. The number of single-turn coils are formed by the wirings of the first circuit board, the wirings of the second circuit board, and conductive rods disposed in the plated through-openings.
