Abstract
A combined electric motor and motor drive are provided. The electric motor and motor drive are attached together to form a co-packaged unit. In the co-packaged electric motor and motor drive, both the motor drive and the electric motor generate heat. A thermoelectric cooler is provided that may transfer heat away from the motor drive. The thermoelectric cooler may also insulate the motor drive from the heat generated by the motor.
Claims20
A co-packaged electric motor and motor drive, comprising:
- the electric motor comprising a stator, a rotor and a first housing enclosing the stator and the rotor;
- the motor drive comprising a plurality of solid state switches converting electrical input power to electrical output power;
- a first conductor supplying the electrical input power to the motor drive;
- a second conductor connecting the electrical output power to the stator;
- and
- a thermoelectric cooler disposed between the motor drive and the electric motor, a hot side of the thermoelectric cooler being in thermal communication with the housing of the electric motor, and a cold side of the thermoelectric cooler being in thermal communication with the plurality of solid state switches.
