Automotive Fan

Sine wave non-inductive FOC control algorithm

Forward and reverse wind start

High temperature speed reduction function

Over current, over voltage, under voltage, over temperature, blocking rotation, lack of phase protection

Single resistor direct closed-loop start, start stable and fast, low speed noise

Single resistance current sampling does not phase shift starting, to solve the problem of low speed starting current noise

High speed downwind start without current and voltage shock

Stable high-speed observer and weak magnetic algorithm

Fast braking function, power failure and voltage loss protection •Low power current within 100uA
