Title:
MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023074608
Kind Code:
A
Abstract:
To prevent controllability of a motor from degrading.SOLUTION: A motor control device outputs a voltage limit value Vth as a voltage command value V** in a case where a voltage command value Vdq* is larger than the voltage limit value Vth obtained by multiplying an input voltage Vin input to an inverter circuit 2 and a modulation factor M1, outputs the voltage command value Vdq* as the voltage command value V** in a case where the voltage command value Vdq* is less than or equal to the voltage limit value Vth, and adjusts a d-axis current command value Id* by proportional control such that a voltage saturation amount Vs, which is a difference between a value obtained by multiplying a modulation factor M2 smaller than the modulation factor M1 and a maximum voltage command value Vm obtained by the input voltage Vin and the voltage command value Vdq*, is small.SELECTED DRAWING: Figure 1
