<P>PROBLEM TO BE SOLVED: To control the rotational speed of a motor such that the acceleration is moderated as the rotational speed increases. <P>SOLUTION: The controller includes a motor generating a drive force dependent on a current being conducted, a driver which can switch a first mode for generating a drive force in the forward direction by conducting a positive current through the motor and a second mode for generating a brake force by generating a regeneration current dependent on the rotational speed of the motor, and a controller for controlling the driver to rotate the motor in the forward direction by generating the first and second modes alternately. <P>COPYRIGHT: (C)2009,JPO&INPIT |
