Abstract: Embodiments of cooling a motor controlling using a motor are disclosed. In some embodiments, a system includes an electric motor including at least one rotor with integrated features positioned and configured to pull air into and through the electric motor. The system also includes at least one motor controller each comprising a heat sink positioned in an air intake path from a source of air to the electric motor. A method of manufacturing the system includes arranging at least one motor controller and at least one electric motor, coupling the at least one motor controller and at least one electric motor via a flexible duct, and adapting the arrangement of the at least one motor controller and the at least one electric motor to passively provide cooling via airflow through the at least one motor controller and at least one electric motor in proportion to a load on the at least one electric motor.

Abstract: Embodiments of a modular motor assembly are disclosed. In some embodiments, a motor comprises a plurality of modular magnetic units, where each of the modular magnetic units includes at least one rotor and at least one stator. The motor further comprises a plurality of structural segments each adapted to support a stator of a corresponding one of the modular magnetic units, where each of the structural segments interlocks with a next structural segment to form a stack. A method of manufacturing a motor includes arranging a selected number of modular magnetic units, coupling the selected number of modular magnetic units to a shaft, coupling the selected number of modular magnetic units to respective structural segments, and forming electrical connections to apply three-phase voltage to stator windings of the modular magnetic units.
