Abstract

A method of operating a positive displacement compressor including the steps: applying a first signal to the motor rotor windings for a first duration of time to align the motor rotor to the initial position; applying a second signal to the motor rotor windings to start rotation of the compressor shaft; applying a third signal to the motor rotor windings for a second duration of time to hold the compressor shaft in place; and applying a fourth signal to the motor rotor windings to accelerate the motor to an operational speed, resulting in a soft expulsion of a fluid inside the compressor at start-up.
