Title: DRIVE CONTROLLER FOR HYBRID COMPRESSORS
Abstract:
A drive controller for hybrid compressors having two driving systems using an engine and a motor, including a central control means for feeding a control signal to a motor input regulating means to increase the amount of input electricity to be given to the motor if a decision that required cooling power is not obtained is made from a signal from a cooling power detecting means, if a decision that the rotating speed of the motor is below a predetermined value is made from a signal from a motor rotating speed detecting means and if a decision that the torque provided by the hybrid compressor is above a predetermined value is made from a signal from a compressor torque detecting means, thereby making optimum control possible during the driving by the motor.
