Automotive stepper motors are historically used to provide miniature adjustments for applications that require reliable, precise actuation. Within vehicles, stepper motors are used inside instrument clusters to provide accurate gauge readings that alert drivers to fuel levels, rate of speed, mileage measurements and more. As vehicle technology has evolved, these gauges have started to move from mechanical to digital.

However, automotive stepper motors play a key roll in new vehicle safety features such as adaptive headlight systems. The basic function of this system is to make minor adjustments, both vertically and horizontally, to the headlight position in order precisely illuminate the roadway. By turning the headlights into a curve, for example, a driver is able to see more objects within the vehicle’s path thus increasing driver awareness and improving response times.

Vehicle efficiency has become a critical selling point for new cars and trucks in recent years as consumers grow more conscious of the environmental effects of carbon emissions. Each component plays a role in overall vehicle efficiency – Brushless DC Motors (BLDC) are a good choice when high efficiency is required without sacrificing performance. This is why BLDC motors are used in many power train and engine applications such as fuel pumps, refrigerator pumps and urea SCR systems.

Many BLDC motors in our lineup can be converted to Automotive grade through the addition of automotive-specific electronics and materials. This integration improves the temperature range and vibration and noise output that is critical to Automotive operation. We also have Automotive dedicated factories that manufacture these components in TS16949 defined environments.
