    摘要: A vector control unit that has an inverter connected with an induction motor which is not only electrically driven but is also being operated in a regenerative condition. The vector control unit comprises a detection circuit for detecting that the induction motor is being operated at a low speed and for detecting that signs of a rotor electrical angular velocity command and a slip angular velocity command differ from each other, and a control circuit for performing control such that the slip angular velocity command is not included in the angular velocity command when the induction motor is being operated at low speed and the signs of the rotor electrical angular velocity command and the slip angular velocity command differ from each other.
