Abstract

PURPOSE:To arrange so that particular place for the detection of magnetic polar position may not be required by extending yoke with permanent magnet fixed on rotary shaft in a right angle direction with a rotary shaft corresponding to a magnetic pole. CONSTITUTION:Ring-shape permanent magnet 3 where plural magnetic poles are formed in alternate polarity, is fixed on the side of yoke 2 fastened at right angle with rotary shaft 1. The part corresponding to a magnetic polar position of permanent magnet 3 on yoke 2 is extended in a right angle direction with rotary shaft 1 and used as a magnetic pole detector piece 4. Also the yoke 2 between the magnetic pole detector pieces 4 is bent at right angle for use as permanent magnet holding part 5 and then magnetic polar sensor 9 for sensing magnetic pole detector piece 4, is installed on a machine frame 6. In this way, particularly no special place for detection of magnetic polar position is required and at the same time, permanent magnet can be firmly held.
