Abstract
A compressor system according to the present invention utilizes direct rotational input from a permanent magnet motor to generate compressed air. The permanent magnet motor is mounted directly to an air screw compressor. The rotational input is provided by the permanent magnet motor to the air screw compressor without a gear train. The permanent magnet motor and associated variable speed drive controls the rotational speed of the permanent magnet motor and hence the screw compressor. Differing motors may selectively mount, and provide rotational input to, the air screw compressor.
