BLDC标量控制驱动器

在标量驱动器内,一般只控制频率和施加在电机上的电压(并不要求控制电流反馈)。
对于永磁3Φ电机(BLDC和PMSM)而言,需要获取转子速度和/或位置信息方可让定子和转子磁通位置保持同步。 在不使用物理传感器(霍尔传感器、编码器等)提取转子速度/位置信息的情况下,驱动器就被视为“无传感器”驱动器。
由于利用这种驱动器很容易实现电机的无传感器控制,所以六步波驱动器(亦即块变换)就成了最常见的、面向PMSM和BLDC的标量驱动器。并且,在六步波驱动器内,可以在电流模式下控制电机电流值,从而实现电机扭矩调节。
由于标量驱动器无需密集的数学计算,所以能够利用低成本微控制器(从8位微控制器开始)实现。
