Abstract

PURPOSE:To effectively start a rotor magnet by driving the initial one revolution of the magnet by two flip-flops, and then switching to drive by a Hall IC. CONSTITUTION:A rectangular wave oscillator 6 outputs a rectangular wave E3, which is counted by a counter 7, and pulses E4-E8 of different phases are output. The pulses E4, E6 are applied to a flip-flop 8, the pulses E5, E7 are applied to a flip-flop 9, and pulses E9, E10 are generated. The pulses E9, E10 are input to drive circuits 1, 2, a current I1 is supplied to drive coils 12, 13, and a current I2 is supplied to drive coils 14, 15. Thus, a rotor magnet 5 starts rotating in a direction of W. When the drive is started, a switch circuit 11 is switched to switch to the drive by the outputs of Hall element ICs 3, 4.
