摘要
Abstract
A line-to-line voltage zero-crossing comparison method is presented for sensorless brushless DC motor( BLDCM), compared to the BLDCM control method using hall position sensor, has an in-depth study of the relationship about commutation signals, commutation logic and running direction. The logic expressions of com mutation signals producing by two methods respectively are given, the only commutation logic which makes sen sorless BLDCM running with line-to-line voltage zero-crossing comparison method is derived, the connection re lationship between inverter and the three-phase windings which makes effects on the motor running is researched. The experimental result shows that the conclusions are correct, practical and valuable in engineering.关键词
