摘要
The present invention relates to a method for estimating a motor parameter in a load commutated inverter arrangement, comprising the steps of: measuring a motor side ac-voltage; detecting commutation interval information of the measured motor side ac-voltage; estimating a motor parameter based on the detected commutation interval information; and indicating when the estimated motor parameter deviates from a monitoring parameter thereof.
