Abstract
A method and system of cooling an enclosure or motor is disclosed. An exemplary permanent magnet electric motor is formed with an external stator and an internal rotor. The motor controller is in thermal proximity to the motor but is thermally isolated from the motor by an air chamber. In one exemplary embodiment, one or more heat sinks are provided to create efficient heat removal paths. In another exemplary embodiment, one of more heat pipes are located in the system.
Claims9
A method comprising:
- transferring heat through an aperture at an end of a motor, through a central opening of a first flange mounted on an exterior of the motor to air contained in an air pocket of a chamber, the chamber being defined by a wall extending from the first flange;
- transferring heat from the air contained in the air pocket through the chamber to an opposite end of the chamber;
- transferring heat from the air contained in the air pocket through a central opening of a second flange of the wall to a side of a heat sink mounted on the second flange;
- and
- transferring heat from a controller mounted on the side of the heat sink and disposed in the chamber to cooling fins disposed on an opposite side of the heat sink.

A method, comprising:
- transferring heat from a motor through a central opening of a first flange mounted on an exterior of the motor to air contained in an air pocket of a chamber, the chamber being defined by a wall extending from the first flange, the wall of the chamber having a sloped top surface for enhancing air flow over the chamber;
- transferring heat from the air contained in the air pocket through the chamber to an opposite end of the chamber;
- transferring heat from the air contained in the air pocket through a central opening of a second flange of the wall to a side of a heat sink mounted on the second flange;
- and
- transferring heat from a controller mounted on the side of the heat sink and disposed in the chamber to cooling fins disposed on an opposite side of the heat sink.
