Title: Dc brushless motor
Inventor: ONO HIROTOSHI
IPC: H02P6/10
Filed: 1985-02-27
Abstract: PURPOSE:To reduce a variation in a torque by feeding back to an input voltage a torque detection signal obtained by multiplying a value converted at the prescribed ratio from a motor drive current by the magnetic flux coefficient of a magnet for correcting a torque ripple. CONSTITUTION:A feedback voltage Vt' is added by an adder A to a command voltage Vt input externally. A motor phi is driven by a motor drive current obtained by amplifying the added result by an amplifier G. The motor drive current I is converted by a stator coil current conversion block K to a current I'=I.K (K is a constant) proportional to the current I. The magnetic flux coefficient phi' of a magnet Mtc for correcting a torque ripple is multiplied by the current I' to output a voltage designated by Vt'=I'.phi, and fed back to an adder A. Accordingly, a loop of the adder A, the amplifier G, a stator coil current convertion block K, the magnetic flux coefficient block phi' of the magnet Mtc, and the adder A forms a feedback loop for detecting the torque of a motor. Thus, it can prevent the torque from varying.
