Title:
MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022130784
Kind Code:
A
Abstract:
To provide a practical control device capable of effectively suppressing motor noise caused by fluctuations in radial force.SOLUTION: A motor control device includes a fundamental wave control unit 13 that calculates a fundamental wave command value for causing a fundamental wave current to flow through a winding of a motor 8, a harmonic control unit 24 that calculates a harmonic command value for causing a radial force suppression current to flow through the winding to suppress fluctuations in the radial force acting on a stator 3 on the basis of UVW axis current command values iu*, iv*, iw*, the phase θre, and a motor constant, adders 16 to 18 that superimpose the harmonic command value on the fundamental wave command value, and an operation unit 19 that operates an inverter 4 such that the driving current obtained by superimposing the radial force suppression current on the fundamental wave current flows through the winding.SELECTED DRAWING: Figure 1
