<P>PROBLEM TO BE SOLVED: To provide a controller for a motor with brush which can alter the output range, by adjusting the position of the brush, according to the output demanded for the motor with brush. <P>SOLUTION: The controller for a motor with brush, including a brush displacement mechanism, has a rotational speed sensor 16 for detecting the rotational speed of the rotor shaft 15 of a motor M with brush. The output signal from the rotational speed sensor 16 is delivered to a controller 10. The controller 10 adjusts the position of the brush of the motor M, according to the rotational speed of the rotor shaft 15 of the motor M detected by the rotational speed sensor 16. <P>COPYRIGHT: (C)2008,JPO&INPIT |
