MOTOR CONTROL DEVICE

An electronic control device (10) includes a map that defines the relationship of a battery voltage (Vb), a motor rotation speed (Ée), and a torque value (T) of a motor (1) with each of the d-axis current command value (Id*) and q-axis current command value (Iq*). During regeneration of the motor (1...

Beschreibung
Zusammenfassung:	An electronic control device (10) includes a map that defines the relationship of a battery voltage (Vb), a motor rotation speed (Ée), and a torque value (T) of a motor (1) with each of the d-axis current command value (Id) and q-axis current command value (Iq). During regeneration of the motor (1), a d-axis current command value (IdTref) based on a torque command value (T) and a d-axis current command value (IdTout) based on an output torque (Tout) of the motor (1) are respectively derived with reference to the map. When the d-axis current command value (IdTout) is greater on the negative side than the d-axis current command value (IdTref), an inverter (2) is controlled according to the d-axis current command value (IdTout).
