Abstract
An improved fluid cooling arrangement for an electric machine, such as an electric motor, a generator, or a motor/generator assembly, is provided. In its most general sense, the fluid-cooled electric machine includes a rotor disposed on a motor shaft, a stator surrounding the rotor, and a motor housing surrounding the stator, with the stator formed of a laminated stack of stator plates that is plated at its outer surface.
Claims12
A fluid-cooled electric machine comprising:
- a rotor disposed on a motor shaft,
- a stator surrounding the rotor, and
- a motor housing surrounding the stator,
- wherein the stator is formed of a laminated stack of stator plates that is plated at its outer surface, and
- wherein a coolant flow passage is defined between the plated outer surface of the laminated stack of stator plates and the motor housing.
A stator that is to form a part of a fluid-cooled electric machine including a rotor surrounded by the stator and disposed on a motor shaft, and a motor housing surrounding the stator, the stator comprising:
- a laminated stack of stator plates, and
- plating at an outer surface of the laminated stack,
- wherein, when the stator is received within the motor housing, a coolant flow passage is defined between the plated outer surface of the laminated stack of stator plates and the motor housing.
