<P>PROBLEM TO BE SOLVED: To obtain a motor driver which can successively operate stably by suppressing a speed variation at a time other than overloading, and further preventing an overcurrent protective device from operating at overloading. <P>SOLUTION: A torque command correcting means is provided, and when the phase current of a brushless motor detected by a current detection means is larger than a preset value, an amount of a torque command decided by a torque control means is decreased. <P>COPYRIGHT: (C)2008,JPO&INPIT |
