PROBLEM TO BE SOLVED: To provide a brushless motor which can prevent the malfunction and power drop by improving the accuracy in detection. SOLUTION: Stators 16 are counterposed at a specified interval around a rotor 18, and a magnetic insulator 18e is provided between the iron core 18c for drive opposed to the stator iron core 16a of the stator 16 out of the rotor 18 and the iron core 18d for positional detection projected from the iron core 16a of the stator. A magnetic sensor 19 is counterposed at a specified interval from the iron core 18d and rotates the rotor 18 by exciting the stator windings in order, based on the information on the rotor position detected by the output. |
