Title:
【発明の名称】ブラシなし直流電動機の転流時のピーク電流抑圧方法
Document Type and Number:
Japanese Patent JP3148269
Kind Code:
B2
Abstract:
A current actual value determination takes place exclusively in the DC intermediate circuit of the converter. The current build-up compared to the current redn. is delayed about a time span (tv). The current redn. is introduced with the arrival of a commutation signal of a rotor position transmitter and the current build up is delayed for the time span (tv). The current redn. before the arrival of a commutation signal of a rotor position transmitter (6) is introduced and the current build up is delayed for the time span (tv).
