Title:
VECTOR CONTROLLER OF INDUCTION MOTOR
Document Type and Number:
WIPO Patent Application WO/2006/033180
Kind Code:
A1
Abstract:
A vector controller of an induction motor capable of correcting the set value of mutual inductance so as to match it to an actual value by additional processing on software without adding any special device. The vector controller (1) of an induction motor comprises a section (3) for determining the correction value of mutual inductance of an induction motor (15) based on the error between a torque operation value calculated using a measurement of the primary current of the induction motor (15) and a torque command value for the induction motor (15) generated at a torque command generating section, and a vector control section (2) for controlling the induction motor such that the generation torque of the induction motor (15) matches the torque command value by using the circuit constants of the induction motor (15) including the correction value of mutual inductance.
