Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019129600
Kind Code:
A
Abstract:
To perform sinusoidal drive with a small amount of calculation.SOLUTION: A control device of a three phase brushless motor includes an externally applied voltage acquisition unit that acquires an externally applied voltage applied to the three phase brushless motor, a rotation speed calculation unit that calculates the rotation speed of the three phase brushless motor, a storage unit that stores a voltage advance map in which the externally applied voltage, the rotation speed, and the voltage advance angle are associated with each other on the condition that Id, which is a magnetic flux component from among the magnetic flux component and the torque component of a phase current, is constant, and a voltage advance angle calculation unit that calculates the voltage advance angle on the basis of the externally applied voltage acquired by the externally applied voltage acquisition unit, the rotation speed calculated by the rotation speed calculation unit, and the voltage advance map stored in the storage unit.SELECTED DRAWING: Figure 2
