Protection function

1. Over current protection of hardware:when the phase current is ≧ 2.43A±5%A and the continous time ≧3.5us,the DC motor stops working.It only can restart after power is off .

   
   

2. Stall the rotation protection:when controller detects the motor speed is ≦750RPM and the continous time ≧0.3s,the engine stops working. It only can restart after power is off .

   
   

3. Open phase protection:when there is any open phase detected by the control board,brushless motor stops working and doesn't work any more.

   
   

4. Low voltage protection:when the PCBA find AC power is ≦75±10V,electric stops working ;when the AC power is ≧ 80±10V,brushless motor return to work.
