<P>PROBLEM TO BE SOLVED: To stop a motor appropriately even if the rotational situation of a motor cannot be known and to sustain the stop state. <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 conducting a reverse current through the motor, and a controller for controlling the driver such that the first and second modes occur alternately for the same time interval when the moving object of the motor is stopped. <P>COPYRIGHT: (C)2009,JPO&INPIT |
