Apparatus and method for controlling torque of induction motor through vector control type inverter |
摘要 |
In apparatus and method for controlling a torque of an induction motor through a vector control method type inverter having a slip frequency calculator arranged for calculating a slip frequency used to perform a vector control for the induction motor and a secondary resistance compensation circuit arranged for correcting the slip frequency by a temperature variation in a secondary resistance of the induction motor, basically a skin effect correction circuit is added for deriving an error component developed in an output of the secondary resistance compensation circuit when a leakage inductance L sigma is non-linearly varied due to a skin effect phenomenon. <IMAGE> |
