Electronic Control BMW Radiator Fan 12 Months Warranty High
Reliability Waterproof 1742 7640 509
Description
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.
Features
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
