Enhance fuel economy and performance with our 48 V auxiliary motor control solutions
The auxiliary motor control system operates in harmony with the internal combustion engine, providing an extra boost during acceleration and heavy load conditions. This assistance not only enhances vehicle performance but also optimizes the efficiency of the engine. By sharing the load with the auxiliary motor, the engine operates within its optimal range, resulting in improved fuel economy and reduced emissions.
The 48 V auxiliary motor control technology paves the way for downsized engines, as the auxiliary motor compensates for reduced engine displacement. This downsizing approach further enhances fuel efficiency while maintaining or even surpassing the performance levels of larger engines.
Designed for motor and heating control auxiliary applications (48 V)
48 V auxiliary applications can be grouped into motor control applications and heating control applications.
