<P>PROBLEM TO BE SOLVED: To provide a compact and low-noise motor drive controller. <P>SOLUTION: This motor drive controller is equipped with a rectifying circuit 2 which receives the input of an AC power source 1, a small-capacity cylindrical film capacitor 3 which is connected between the output points of the above rectifying circuit 2, and an inverter circuit 4 which drives a motor 5 connected to the output of the above rectifying circuit 2. This is compact and does not generate noise without using a cover or the like to counter noise because the noise by the current voltage pulsation of the inverter generated from the film capacitor 3 decreases. <P>COPYRIGHT: (C)2007,JPO&INPIT |
