When matching motor characteristics to compressor requirements, one should consider factors such as voltage, phase, and duty cycle. The motor’s rated horsepower should ideally be closely matched to the compressor’s demands to ensure optimal performance.
[pdf] Rotary screw electric air compressors provide a continuous supply of air. They have two internal screws that rotate in opposite directions, trapping and compressing air. The constant movement differs from piston air compressors that start and stop to meet air flow needs.
[pdf] The Positive Temperature Coefficient (PTC) thermistor causes the compressor “run” capacitor to be bypassed for a brief period of time at start up, creating extra starting torque in the compressor motor.
