| Abstract: | The operation of an elevator requires accuracy and safety.The condition of electricity generation in electromotor exists during elevator's operation.Various operation states of the elevator are analyzed on the basis of fundamentals of electromechanics,pointing out that regenerative braking has advantages in the frequency-conversion drive and the best approach to the safety operation and electricity saving is to add regenerative braking unit to the existing dynamic braking of a frequency convertor. |
