Automatic air conditioning. Automatic seat adjustments. Automatic rearview mirrors. Automatic parking. Cars have evolved from manual operation to electric operation to intelligent automatic operation, making driving a more pleasant experience. Playing a vital role in these operations is the motor control system. There are 2 types of motors, with the brushless DC motor being quieter than the brush motor. It is also safer as the lack of brush friction doesn’t cause sparks or charcoal dust.
The S32K144 Automotive Sensorless FOC Controller from Avnet offers higher efficiency and reliability with lower noise and cost. With its wide range of peripheral units and multi-pin models, the 32K meets the flexibility requirements of this type of application. It can also meet high-voltage application requirements, be it for the 24V commercial vehicle truck or the new energy car motor. And it works better than asynchronous motors to save energy and reduce carbon emissions.
