PURPOSE:To enable high-speed rotation to be performed, by setting a magnet rotor to be of an internal rotation type, and by setting position detecting signal to be of the range of 90 degrees at an electrical angle through a starting point. CONSTITUTION:A transistor bridge circuit worked with feed from a DC power positive-terminal 21 is composed of transistors 48a, 48b... and armature coils 2a, 2c. By the output of an AND circuit 51a, the transistors 48a, 48b are turned conductive, and by the output of an AND circuit 51b, the transistors 48c, 48d are turned conductive, and so current is conducted to the armature coils 2a, 2c in the forward or reverse direction by being reciprocated in the range of 90 degrees. The charged electric charge of capacitors 54a, 54b is conducted to the armature coils 2a, 2c, and is contributed to output torque. |
