Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066995
Kind Code:
A1
Abstract:
This motor control device 10 is provided with: a command current deriving unit 33 for deriving a command current vector on the basis of a command torque TR* for a brushless motor 100; a phase difference deriving unit 18 for deriving a phase difference Δθ between the direction of an actual d-axis of rotational coordinates for vector control and the direction of an estimated d-axis; a changing unit 34 for changing the direction of the command current vector, derived by the command current deriving unit 33, in accordance with the phase difference Δθ; and a drive control unit 25 for driving the brushless motor 100 on the basis of the command current vector of which the direction has been changed by the changing unit 34.
