Additional protection functions can be added: AS automatic lock/start function, slow start function, over current protection,motor lock current protection, reverse connection protection, over voltage protection, PWM, FG, RD, IP55, IP68

FG (speed output signal)
FG function is also commonly referred to as tach out. This function is mainly used to output a square wave signal from the inside of the fan, and the frequency of the signal represents the speed of the fan. Conventional four-stage fan: speed = FG frequency *30. That is, the fan speed can be read by reading the FG signal.
RD signal (stall alarm function)
The RD function is also known as the alarm signal. RD is low when the fan is running and high when the fan is locked. Judge
whether the fan is in normal operation or locked state by monitoring the RD signal level.
PWM speed regulation function
PWM refers to pulse width modulation. It means that the frequency (period) of the pulse signal is fixed, and the width ratio (duty cycle: that is, the space ratio) of the pulse wave is changed by the size of the input signal (DC). The on cycle and off cycle of the pulse signal are changed to change the speed of the fan, so as to save energy and reduce noise.
Introduction to waterproof function
1: Glue filling process:IP68 grade The fan runs in water 2 :Vacuum coating process:Ip55-ip68 grade The fan can run with water! The cost is lower than glue filling

Specifications

 

 

Sleeve Bearing
Sleeve bearings generally use friction sliding sleeves (s). The fan blade axis uses lubricating oil as lubricant and drag reducer, but the lubricating oil will volatilize and cause friction. The service life is lower than that of ball bearings, and the service
life is generally 30000 hours

 

Ball bearing
Ball bearing: the model is generally represented by (b). Several small steel balls in the bearing rotate around the axis, so the friction is small and there is no oil leakage problem. The advantage of double ball bearing is long service life, suitable for long-term 24-hour uninterrupted operation and high-speed fan, with a service life of 50000-70000 hours.
