Title:
MOTOR DRIVE FOR MOTOR COMPRESSOR AND MOTOR CONTROL METHOD
Document Type and Number:
Japanese Patent JP2015089304
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor drive of a motor for motor compressor in which electric power is not wasted but can be used efficiently, and start-up failure does not occur when restarting immediately after stoppage.SOLUTION: After stopping the driving of a motor 3 giving a rotational driving force to a rotor, the motor 3 is rotated reversely at a rotational speed slower than the reverse rotational speed of the motor 3 generated by the pressure difference between a low pressure refrigerant and a high pressure refrigerant, and an electromotive force generated by reverse rotation of the motor 3 is supplied to a drive power supply 5 and regenerated. Consequently, the electric power is not wasted but can be used efficiently, and start-up failure does not occur when restarting a compressor immediately after stoppage.
