摘要 |
A speed control apparatus for an elevator using V.V.V.F. control including a power conversion device, an induction motor and a control device. The control device detects a secondary magnetic flux value from an output current of the power conversion device and generates a control command value for smooth operation of the elevator based on the velocity of the motor and the secondary magnetic flux value.
