Filed: 1989-02-23
Abstract: PURPOSE:To reduce the extent of backlash largely by providing an oval forming member of a wave motion generator with a ringlike flexible spline part which is further intensified in ovality with a four-point supporting system. CONSTITUTION:When a flexible spline 3 is relaxed with a wave motion generator 4 being made up of combining a cam plate 5 and a ball bearing 6 together, four balls 16-19 serving as a criterion for forming an oval are deformed so as to pull out each flexible spline part situated in respective positions to the radial outside.

With this engagement, they are made into face-to-face engagement at both sides of a major axis of the wave motion generator 4, and then preload is imposed thereon at the part. Therefore backlash can be eliminated.

Abstract: PURPOSE:To realize the decrease in power consumption necessary for a brushless motor, to improve temperature characteristics, and to reduce cost by using a magnetoresistance effect element as a magnetoelectric transducer to detect magnetic poles of a rotor magnet. CONSTITUTION:This is a magnetic pole detector which controls energization of a magnetoelectric transducer 20 which detects magnetic poles of a rotor magnet 7 and drive coils on the basis of detection signals of this magnetoelectric transducer.
