Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/079791
Kind Code:
A1
Abstract:
The purpose of the present invention is to appropriately control the driving of a variable field motor in accordance with change in magnetic field. This motor control device (1) controls the driving of a variable field motor (M) having a variable field mechanism capable of changing field magnetic flux. The motor control device has: a field ratio calculation unit (14) which is configured so as to calculate a field ratio of the variable field motor (M); and a motor parameter correction unit (17) which is configured so as to calculate motor parameters (∆θ, ϕ, Ld, Lq) of the variable field motor (M) on the basis of the field ratio calculated by the field ratio calculation unit (14). The field ratio calculation unit (14) calculates the field ratio by means of table conversion on the basis of a torque command (Tref) and a motor speed (ω).
