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.
