Generally, the number of coil windings T and coil resistance of the motor 4 etc. are as follows:
If the size of the coil is constant, as shown in FIG. 4, the resistance increases as the number of turns T increases. Therefore, if the motor is driven by a step-up power source, the ampere-turn of the motor can be kept constant (that is, without reducing the output torque of the motor), and the motor can be driven with less current consumption. Also,
As shown in FIG. 5, in general, when the gate-source voltage VGS of a C-MOS transistor is high, the on-resistance RO
Since M becomes smaller, if the boosted voltage fiVoo is used as a drive power source, the power consumption of the C-MOS section can be reduced and the size of the motor drive circuit can be reduced.
