Pump Control

Pumps in EVs' thermal management systems play an integral role by circulating coolant or refrigerant to sustain optimal temperatures for key components, including the battery, power electronics, motor, and cabin. Addressing evolving pump motor driver requirements, Allegro's focused initiatives deliver solutions offering enhanced power density, efficiency, and precision, coupled with ultra-low noise, all in an efficient package. Allegro's QuietMotion products, leveraging optimized algorithms rooted in sinusoidal and field-oriented control (FOC), mitigate acoustic noise during start-up and during speed and torque regulation. This comprehensive solution streamlines the design-in process, enabling customers to prioritize thermal management over complex noise reduction motor control techniques.
