Abstract

PURPOSE: To operate current control, independent of the rotational speed of a rotor, by adjusting current command signals in accordance with the position of the rotor and thereby controlling the armature coil current.
CONSTITUTION: Stator magnetic path unit 3 is provided with hole elements 101 to 103 and also with pulse generator 130, which detects the indented part of disk 1 integrated with rotor field magnet 2. In accordance with the rotor position signal output from hole elements 101 to 103, transistors T1 to T6 are ignited.. Transistor TR, which controls the current of armature coils MU to MW, is ignited in accordance with signal S1, which corresponds to the rotor position signal output from hole elements 101 to 103, signal S2, which corresponds to the rotor position signal output from pulse generator 130, and difference signal Is, which shows the difference between current command signal is and feedback signal if.
