Drehbewegungs-Regelkreis für einen Motor mit Hall-Elementen. |
摘要 |
A rotation control circuit for a Hall motor of reduced-size and suppressed irregular rotation and having a controller (34) that stores in a memory circuit (34A) data indicative of an irregular magnetization of a rotor magnet (20A) derived from a change of the magnetic field of the rotor magnet (20A) detected by a Hall element (H1,H2,H3) as an irregular rotation information signal, in which the irregular rotation information signal is input to a speed servo loop of the Hall motor, whereby the change of magnetic field of the rotor magnet (20A) is used as an FG signal to form a speed servo circuit. |
