| titleOfInvention | MOTOR DRIVE DEVICE AND ELECTRIC DEVICE HAVING COMPRESSOR USING THE SAME |
| abstract | An object of the present invention is to reduce the power consumption of a device by increasing the efficiency of a motor drive device. A brushless DC motor, an inverter for supplying electric power to the brushless DC motor, and position detection means for detecting a rotor position of the brushless DC motor are provided, and the inverter is obtained by the position detection means. The brushless DC motor is composed of six switching elements that are turned on or off according to a position signal, and is advanced from the timing of turning on the timing for turning off the switching element of the inverter with respect to the position signal of the position detecting means By adjusting the power supply period, the on-time ratio by PWM control is increased, the high-frequency current component of the brushless DC motor is suppressed, and the iron loss of the brushless DC motor can be reduced.
