<p><P>PROBLEM TO BE SOLVED: To solve the problem in which unnecessary electricity is consumed because electric power is always supplied even if an actuator is stopped other than standby state. <P>SOLUTION: An air-conditioner includes: a voltage conversion means 2 that converts AC voltage for commercial power supply from a rectified high-voltage direct current voltage into low-voltage output voltage; a fan motor 6 that operates by assuming direct current as control power supply outputted from the voltage conversion means, and in which the number of rotation is controlled by switching the high-voltage direct current and applying it to a motor winding; a variable means 7 that varies the motor control power supply voltage; and a control part 8 that receives a start-up instruction, outputs the motor an instruction of the number of rotation and inputs a variable width signal into the variable means and operates by making a micro computer that varies the control power supply voltage to the motor, thereby decreasing the control power supply voltage of the fan motor when fan motor suspension condition is met in also conditions other than a standby condition. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
