PROBLEM TO BE SOLVED: To provide an air conditioner whose reliability is not impaired and which is equipped with a blower responding to the requirement to the air conditioner and to provide its control method. SOLUTION: A brushless DC motor is adopted as a motor for the blower. An inverter which is required for driving the motor and a one-chip monolithic IC, in which a peripheral control circuit is integrated are built in the motor. Thereby, the output of the air conditioner can be increased by the control of the input DC voltage of the motor, in addition to PWM control by the inverter. |
