Achieve maximum motor performance and efficiency while staying within safe thermal limits with our temperature sensing solutions

In motor-control applications, our temperature sensors keep motors from exceeding safe operating temperatures that could lead to overheating, bearing failures, overloads or winding faults. Concurrently, enabling operation closer to thermal limits achieves peak motor-control performance without shortening motor life.

Benefits:

  • Cooler/heater activation at elevated temperatures guards battery-management systems and system health while reducing system downtime.
  • Safe power management increases the performance of other sensors and extends component lifetimes.
