NUMBER OF COIL TURN REVISION MOTOR FOR RECIPROCATING COMPRESSOR AND METHOD FOR REVISING NUMBER OF COIL TURN

摘要

PROBLEM TO BE SOLVED: To provide a motor for cooling-heating capacity changing for a reciprocating compressor overcoming the problems involved in switching of the AC switching elements to correspond to the fluctuations in load and voltage. SOLUTION: The number of coil turns of the cooling-heating capacity changing motor itself is made variable by fluctuations in load and voltage to enclose the number of turns variable part 500 capable of carrying out stroke control to constitute the motor for the cooling-heating capacity change for the reciprocating compressor as the number of coil turn changing motor.
