Advantages of STO Water Pump:

1. Control Module: IPM integrated chip is adopted, the overall efficiency is increased by 20%.

2. Stator: The stator motor adopts slotless type, with large torque, small fluctuation, stable operation and 20% noise reduction.

3. Rotor: The rotor is small in size, the motor stator casing is changed to stainless steel to prevent cracking, and a 2-parts magnet structure is adopted, the magnetic force is more uniform, and the anti-demagnetization ability is enhanced by 5%.
