Project : BLDC Motor for Active Eco Pedal System (2009. 12. 01 ~ 2010. 06. 01)
Recently, the concern with "Eco Drive" has been growing. "Eco Pedal System" is one of the important Eco Drive elements being realized. So What is Eco Pedal system? If we press our foot down sharply on the pedal, repulsive power is generated from BLDC motor in the pedal system, and the power prevents from speeding. Therefore the Eco Pedal system makes us drive in the fuel-efficient region and drive safely.
This figures show the waveform of hall sensor signal input and three phase terminal voltage.
