Abstract
An electric motor and related components, such as a motor controller assembly, are disclosed having a coolant circuit where the related components are cooled by the same fluid flow that cools the electric motor. The compact coolant circuit minimizes the need for external lines between the electric motor and related components, while providing separate heat sinks for the electric motor and, for example, a motor controller assembly. The liquid-cooled electric motor and related components may engage and power a variety of reduction output assemblies to form drive assemblies. The coolant circuit of the electric motor and its related components cooperates with an external coolant circuit to form a cooling system. The external circuit may include a radiator (e.g., heat exchanger or oil cooler) and an electric pump for the coolant which may cool one or more drive assemblies of a vehicle drive system.
