Abstract

PURPOSE: To reduce the input of a motor and reduce the dimension of the motor by allowing the piston position where the maximum load torque per cycle is generated and the max. torque generating revolution angle to nearly coincide and utilizing the max. torque of the motor effectively.
CONSTITUTION: A rotor 18 is at the position, for the armature coil 14, where each magnetic field formed by a field magnetic pole 18b and an armature coil 14 crosses at right angles, namely at the position where the torque of the motor 11 becomes the maximum. In this case, a compressor 3 is installed so that a piston 8 is at the position where the load torque is largest between the discharge valve opening point and the top dead center. As a result of this, even if the min. torque in the valley area in the torque of the motor 11 reduces lower than the max. load torque, the motor 11 can provide a necessary torque for a compressor 3, and the input of the motor 11 and the dimension can be reduced.
