BLDC Motor Control Solutions

Renesas Electronics Corporation

BLDC motor control technology turns cars that can safely run in any environment into a reality!

In colder climates, the oil occasionally congeals under the low-temperature, slowing the rotation of electric oil pump motor occurs. Furthermore, it is difficult to detect the motor rotation position in controlling the sensorless brushless DC motor (BLDC) when it becomes a low speed due to the structure. Forcefully rotating the motor without knowing the position of the rotors has a negative impact on power efficiency and noise.

At Renesas, we have developed dedicated control software to allow BLDC motors to rotate at all speed ranges, thereby allowing low-noise/low-vibration motor control under any environment.
