Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/095330
Kind Code:
A1
Abstract:
This motor control device comprises: a current detection unit that acquires a current detection value corresponding to current flowing through an AC motor; a current control unit that acquires a current command value for the AC motor, and that calculates a voltage command value for the AC motor, at each prescribed calculation period, on the basis of the current command value and the current detection value; and a voltage control unit that executes, at each calculation period, control calculation based on the voltage command value, and obtains a duty command for generating a gate signal. The current detection unit acquires the current detection value at least twice in each calculation period. The voltage control unit obtains at least two types of duty command in each calculation period and reflects the same on the gate signal.
