Abstract:
A motor drive control device includes a PWM circuit configured to generate an excitation current for a motor, a measurement circuit configured to measure a charge duty of the excitation current, an arithmetic circuit configured to obtain a characteristic line from the change of the measured duty and calculate a predetermined division point of an excitation current waveform from the characteristic line, and a setting circuit configured to set a level of the excitation current at the division point.

Claim (Index 11):
A motor drive control method comprising:\n generating an excitation current for a motor excitation coil based on one or more parameters; measuring a change of a duty of the excitation current in the excitation coil; obtaining a characteristic line from the change of the duty; calculating a predetermined division point of an excitation current waveform from the characteristic line; and setting a level of the excitation current at the predetermined division point as one of the parameters, such that the excitation current is generated to provide the level of current at the predetermined division point.
