Better NVH performance     

Motor design: better PMSM electric motor helps to produce required torque while keeping itself quieter.

Gear Pump design: customized gear pump design helps to improve the NVH performance.

- Electrical hardware: motor position sensing technology helps to reduce torque ripples.

- Control software: precise control algorithms (including sinusoidal motor control) help to reduce the fluid turbulence in the fluid.
Fully conforms to “Quick response” requirement
Steering velocity is calculated according to the steering angle received.

- A proprietary algorithm  is uesd for quick response to steering maneuvers.

- Steering velocity acceleration rate is also taken into account and utilized to improve the quick response performance.
Less current consumption compared to other equivalent products
Control algorithm is designed to minimize the chance of generating huge current spikes.

- Motor control phase advance angle is monitored and controlled using current consumption feedback.

- Motor control angle is optimized to reduce current consumption at idle speed.
