Design considerations

  • 50 W – 400 W Brushless DC motor drive
    BLDC preferred for controllability and low power performance
  • Controlled by 6 MOSFETs operated with PWM
    puts the focus on switching losses and EMC performance\power saving of 100 W on average emission reduction of approx. 0.24 kg CO2 per 100 km.
  • Applications face a high ambient temperature
