The end of sensor-based BLDC control?

May 18, 2011 // By Thomas Freitag
Vehicle manufacturers are increasingly appreciating the benefits of brushless DC (BLDC) motor control as a response to the challenges of making their fleet meet legal fuel economy regulations. Brushless DC motor control typically increases efficiency 20% to 30% compared to equivalent speed controlled DC solutions. Furthermore they may offer a weight and size reduction of up to 50% especially in high temperature environments like in the power train. Electric and hybrid vehicles generate less noise especially at lower speeds, making low noise BLDC motors the preferred solutions for pumps and fans that have been taken off the belt.
