摘要
论述了交流提升机采用全数字交 交变频器进行低频制动时低频电压值的计算方法。讨论了为保持电机最大转矩不变而低频供电时 。
A calculation method of low frequency braked voltage of full digital control cyclo converter in hoist system is introduced.The influence of the stator resistance voltage drop on low frequency braking voltage when supplying with low frequency AC resouce to keep the maxim torque is considered.
