<P>PROBLEM TO BE SOLVED: To provide a brushless DC motor of a motor driver 1 which can rotate at the highest efficiency even in the state of forward or reverse rotation. <P>SOLUTION: In the brushless DC motor 10 of the motor driver 1, a Hall IC 34 can be switched to the forward rotation detecting position and a reverse rotation detecting position of a rotor, by disposing a detecting substrate 32 fixing the IC 34 out of a motor casing 30, inserting the detector of the IC 34 into the casing 30, movably disposing a detecting substrate 32 by a changeover switch 40, and movign a detecting substrate 32 by the switch 40. <P>COPYRIGHT: (C)2004,JPO |
