Publication number: 20060039807Abstract: A compressor includes a motor driven by a controller and having a rotor and a stator, a compressing unit driven by the motor in a hermetic container in which refrigerant is filled. Driving the motor at a low rpm, the controller practices a feedback control which determines a timing of turning on/off switching elements based on a signal detecting a position of the rotor, and when the motor is driven at a high rpm, the controller practices an open-loop control which outputs a given frequency and drives the motor synchronizing with the given frequency. This structure achieves a compressor working with a fewer noises in PWM driving.Type: ApplicationFiled: March 16, 2004Publication date: February 23, 2006Inventors: Koji Hamaoka, Hidetoshi Nishihara, Katsumi Endo, Makoto Katayama, Shuichi Yakushi, Tatsuyuki Iizuka, Yuji Saiki, Hidehisa Tanaka, Tomonori Ouchiyama
