Abstract

PURPOSE:To reduce the cogging, by making the board thickness of a back yoke thin and by jointing a non-disc-shaped subback yoke. CONSTITUTION:A plane-faced type brushless motor is composed of a back yoke 1, a stator coil 2, a connector 3, a rotor magnet 4, a bearing 5, a driving shaft 6, etc. On this occasion, the board thickness of the back yoke 1 is set so that the leakage flux is generated in its rear as the magnetism gets saturated for the flux generated by the rotor magnet 4. A subback yoke 7 made of non- disc-shaped magnetic material is jointed and installed to the rear of the above back yoke 1. With this subback yoke 7 the flux generating rotor magnet 4 is deflected, so that the flux distribution is made uniform as a result and no cogging will be generated any longer.
