Abstract
PURPOSE:To eliminate noise while extending the life with a less number of component parts by detecting the position signal with a sliding element rotating on the resistor by means of a common electrode provided at the center of the disc resistor and corresponding phase electrodes on the circumference thereof. CONSTITUTION:A common electrode 3 is provided at the central part of a disc resistor 2 and corresponding three phase electrodes 4-6 on the circumference thereof to form a position signal stator 1. A slide element 7 is arranged to slide to match the rotation of the rotor contacting on the resistor 2 of the position signal stator 1 whereby the output signals from the phase electrodes 4-6 are fed to respective power transistors 29-31 by way of transistors 25-27. As the rotor rotates, the output of the phase electrodes 4-6 changes in sequence. It is so arranged that the power transistor connected to the electrode which is the largest in it output is caused to conduct to energize the stator windings 32-34 in sequence.
