To provide an electronic circuit for a magnetic rotating apparatus taking out efficiently a rotating energy from a permanent magnet by the smallest possible electric energy, and easily controlling its rotation.
A dedicated electronic circuit for magnetic rotating apparatus includes: a rotating portion composed of non-magnetic material on which periphery a permanent magnet group inclined by a predetermined angle is embedded; an electromagnet group arranged close to the rotating portion so as to be opposed to the permanent magnet group; and a position sensor for detecting the position of the permanent magnet group. The circuit is designed to drive the rotating portion to rotate by applying electric current to the electromagnet in accordance with detecting signals of the position sensor. It is also designed to connect a switching device via a positive diode and a negative diode relative to a power source, and turn the switching device on/off in accordance with the detecting signals form the position sensor, and to excite the electromagnet group with an end-to-end voltage of the negative diode.
