Document Type and Number:
Japanese Patent JP2019054607
Kind Code:
A
Abstract:
To provide a motor drive control device capable of easily generating an excitation current pattern of a pseudo sine wave and a control method of the same.SOLUTION: The motor drive control device includes: a measuring circuit that measures a duty of an excitation current flowing through a motor; an arithmetic circuit for obtaining a characteristic line from a measured change in duty and calculating a predetermined division point of an excitation current waveform from the characteristic line; and a setting circuit that sets a level of the excitation current at the division point.SELECTED DRAWING: Figure 1
