PROBLEM TO BE SOLVED: To provide a brushless motor 1 that is small in size and that has a simple structure.SOLUTION: When a control circuit 60 controls switches 52a, 52b and 52c to transmit a high-frequency AC power from a power transmission coil to a power reception coil for each phase by magnetic field resonance type electromagnetic induction, in the case that a non-conductor and a conductor are arranged between the power transmission coil and the power reception coil, torque is generated between the arranged conductor and the power reception coil on the basis of the high-frequency AC power. The control circuit 60 makes the high-frequency AC power be transmitted from the power transmission coil to the power reception coil for each phase so as to move the power reception coil that generates the torque to the conductor toward one side in a circumferential direction. Thereby, a rotation part 32 rotates to the other side in the circumferential direction. |
