300w Chevrolet Radiator Fan With High Power Factor Brushless Dc Motor

It is mainly used for engine heat dissipation and coolant cooling to ensure that the engine will not cause high temperature failure.

Automobile engines must be moderately cooled under high-temperature working environments to keep them working at appropriate temperatures in order to meet the requirements of good engine performance, durability and exhaust emissions. The engine cooling system plays a key role here. It mainly includes components such as cooling fan, water tank, thermostat and so on.

• Electronic control is used to obtain similar DC motor operating characteristics, with better controllability and wide speed range.

• Requires rotor position feedback and electronic multi-phase inverter driver.

• It is an AC motor in essence. Because there are no sparks and wear problems of brushes and commutators, it can work at high speed, can obtain high reliability, long working life, and does not require frequent maintenance.

• Brushless DC motor has high power factor, no loss and heating of the rotor, and high efficiency
