Title:
COMPRESSOR, REFRIGERATION CYCLE DEVICE, AND METHOD FOR CONTROLLING COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2015/166580
Kind Code:
A1
Abstract:
A compressor according to the present invention is provided with a shell (1), a compression mechanism unit (5) that is disposed in the shell (1) and compresses and discharges an inflowing refrigerant to outside, a motor (3) that has a permanent magnet (3b) and supplies power to the compression mechanism unit (5), and a control device (14) that applies a voltage having a non-conduction interval for detecting an induced voltage of the motor (3) to the motor (3) to control power supplied to the motor (3). The temperature of the magnet is estimated on the basis of the induced voltage detected in the non-conduction interval, whereby the temperature in the compressor can be estimated with high accuracy and high performance and high reliability can be maintained.
