20 Feet Hvls Air Gearless BLDC Ceiling Fan 1.5kw For Air Ventilation

16feet 20feet big diameter size Hvls Industrial Large Air Gearless BLDC Ceiling Fan for warehouse air ventilation

1.PMSM adopts unique electromagnetic structure design and modular automatic production line process.

2.The internal coil circuit adopts the module splicing scheme design and the automated winding, splicing and welding process.

3.Optimize the electromagnetic circuit design so that the cogging torque ripple is 0. The motor operation speed fluctuation is plus or minus 1 rpm, making the motor operates more smoothly and reliably. It also has extremely high control accuracy. The torque curve is smoother.

4.The unique heat dissipation structure design enables the motor surface temperature rise ≤55°C (including ambient room temperature) during long-term full-load operation.

5.High efficiency and energy saving; efficiency ≥ 90%
