Title:
SYNCHRONOUS MOTOR CONTROLLER
Document Type and Number:
Japanese Patent JP2017184503
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a synchronous motor controller capable of simplifying a calculation part for calculating a d-axis current command value and a q-axis current command value the armature current of which is the minimum.SOLUTION: Disclosed synchronous motor controller 10 has a q-axis current command value calculation part 74 that calculates a q-axis current command value Iq_ref by using a d-axis current command value Id_ref which is calculated by a d-axis current command value calculation part 73 based on the following formula 1, wherein: Ld is d-axis inductance, Lq is q-axis inductance, and Φ is induced electromotive voltage constant.SELECTED DRAWING: Figure 4
