<P>PROBLEM TO BE SOLVED: To solve the problem that, when an AC input DC motor is used in an area where high AC power is used, such as Europe, for example, the voltage of DC power obtained by rectifying the AC power is increased, a coil current must be reduced, the line diameter of a driving coil must be reduced, and the number of the windings must be increased to drive the motor, and the driving coil is like broken and manufacturing is not easy. <P>SOLUTION: In the AC input DC motor which inputs AC power 11 and rectifies the AC power in an inner rectifying part 12 so as to convert it into DC power, the DC power is converted into a low voltage DC power by a low voltage means such as a DC-DC converter 13 and so as to drive the motor by the low voltage DC power. The AC input DC motor can be compatible with high AC power supply area without the change of the driving coil and the motor can be downsized as a whole. <P>COPYRIGHT: (C)2004,JPO |
