Title: Controller for ac electric motor
Inventor: IURA HIDEAKI
IPC: H02P23/14
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To match a voltage command value with the actual value of an AC electric motor and to highly precisely control the AC electric motor even if a power converter without an output voltage sensor is used. SOLUTION: A current detector 3 detects the current value of a current supplied to an AC electric motor 2 and outputs it as current detection values Iα and Iβ.
