Cooling Fan

Thermal energy flows in and around a vehicle are vital and the role of the cooling fans even in hybrid and battery driven vehicles is critical. This helps maintain the optimal temperature range while lowering fuel consumption and emissions. These cooling fans tend to be high power systems often operating up to 1.2 kW

Design considerations

1.2 kW Brushless DC motor drive

  • LDC 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.
