ROTOR FOR SYNCHRONOUS INDUCTION MOTOR AND MOTOR, SYNCHRONOUS INDUCTION MOTOR, INDUCTION MOTOR, DC BRUSHLESS MOTOR, HERMETIC COMPRESSOR, REFRIGERATOR, AIR CONDITIONER, AND MANUFACTURING METHOD FOR SYNCHRONOUS INDUCTION MOTOR
ROTOR FOR SYNCHRONOUS INDUCTION MOTOR AND MOTOR, SYNCHRONOUS INDUCTION MOTOR, INDUCTION MOTOR, DC BRUSHLESS MOTOR, HERMETIC COMPRESSOR, REFRIGERATOR, AIR CONDITIONER, AND MANUFACTURING METHOD FOR SYNCHRONOUS INDUCTION MOTOR
PROBLEM TO BE SOLVED: To provide a rotor for synchronous induction motor capable of preventing the lowering of output or efficiency due to increasing magnetic resistance even if a gas venting hole is formed for using a hermetic compressor.;SOLUTION: This rotor includes slots for generating induction torque and slits for generating reluctance torque. The slot and the slits are filled with aluminum. The filling aluminum is shorted by end ring at both ends of the rotor, and a non-filling section axially passed through the slit and not filled with aluminum is provided.;COPYRIGHT: (C)2003,JPO
