Compressor including a motor and motor control in the compressor housing and method of manufacture

DETAILED DESCRIPTION It is an object of this invention to provide a compressor including motor and integral motor controls sealed within the compressor housing which is inexpensive to manufacture and simple to assemble.
It is another object of this invention to provide a compressor including motor and motor controls sealed within the compressor housing which cools the power switching devices of the control circuit of the motor and avoids the need for separate cooling fins or other heat sinks for the power switching devices.
It is another object of this invention to provide a compressor including motor and motor controls sealed within the compressor housing which is powered by direct current and operates at variable speed without requiring a capacitor to clamp or otherwise condition the direct current.
It is still another object of this invention to provide a compressor including motor and motor controls sealed within the compressor housing which is employs Hall effect sensors to monitor the position of the rotor of the motor.
It is yet another object of this invention to provide a compressor including motor and motor controls sealed within the compressor housing which is used with a integrated control for the refrigeration system, the control being part of the condenser motor and integrated therewith.
It is another object of this invention to provide a compressor including motor and motor controls sealed within the compressor housing which is bidirectional.
It is another object of this invention to provide a compressor including motor and motor controls sealed within the compressor housing which efficiently operates and maximizes compressor performance.
In one form, the invention comprises refrigeration system to be driven by an electrical power source.
A compressor mechanism in a hermetically sealed compressor housing circulates a refrigerant located within the compressor housing through a loop.
The loop includes an evaporator adapted to permit the refrigerant in the evaporator to absorb heat and a condenser adapted to permit the refrigerant in the condenser to dissipate heat
