Title:
PERMANENT MAGNET ROTATING ELECTRIC MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/129042
Kind Code:
A1
Abstract:
A control device (10) converts phase currents (Iu, Iv, Iw) supplied to a permanent magnet rotating electric machine (11) into d-axis current (Id) and q-axis current (Iq) on the dq coordinate axis. Based on a torque command (T), the d-axis current (Id), and the q-axis current (Iq), the control device (10) calculates current commands (d-axis current command (Id*), q-axis current command (Iq*)) for changing at least one of the values of the d-axis current (Id) and the q-axis current (Iq) in accordance with a rotor position so that the magnitude of a reverse magnetic field acting on an end of a permanent magnet becomes less than or equal to the coercivity of the permanent magnet.
