主动增益控制(AGC)技术

实时优化驱动电流的简单系统

为确保所需电机扭矩具有足够的裕度,电机控制驱动IC(MCD)通常提供大于最大负载时峰值电流的电机驱动电流。这意味着额外的电流会一直持续流动。为最大限度减少不必要的电流消耗,使用传感器或微控制器来监测负载条件的变化,从而根据负载条件调整电机驱动电流。这种反馈过程需要极其复杂的控制。东芝提供结合了主动增益控制技术的电机驱动IC,该技术能够感应电机的负载扭矩并自动优化电机驱动电流。这使得在简化高效电机控制的同时,可以防止电机失步。

提高效率、节能、显著降低电机散热
提高效率,节约能源,显着降低电机散热

AGC技术根据电机的负载条件自动调节电机驱动电流,以减少额外的电流,从而大大减少电机驱动IC和电机产生的热量。这有助于减少系统中的总热量产生和由此产生的退化。
