Automotive BLDC applications US: Essential in EV drivetrains, power steering, and HVAC.
Automotive BLDC applications in the US are undergoing a massive expansion beyond the traditional auxiliary systems. Historically, BLDC motors were used for secondary functions like power seats, power windows, and electronic throttle control. The industry's current focus is on their integration into Electric Vehicle (EV) powertrains, where their high power-to-weight ratio, exceptional efficiency, and precise torque control make them ideal for traction motors. Furthermore, they are replacing less efficient motors in crucial thermal management systems, such as HVAC blowers and electric coolant pumps, which are essential for maximizing the driving range and battery life of EVs. The shift is mandated by the automotive industry's pursuit of light-weighting and minimizing parasitic losses in both ICE and EV platforms, with BLDC technology being the preferred solution for maximizing every watt of power.
