specific steps are as follows
1, Use a multimeter to measure any 2 of the 3 wires, find out the largest resistance value, mark 1.
2. Connect the capacitor to mark 1.
caution
1, the fan shaft part is to ensure that there is lubricating oil, otherwise the wind blade can not drag the motor on the above. If you are at home, you can choose to turn off the power, and then flip the wind blade, if the rotation is stiff, basically there is no lubricating oil.
2, wear caused by a long time. If a fan is used for a long time, the motor will be lost, and the shaft sleeve of the motor will be easily burned after wear.
3, overheating caused by the fan does not turn. There is a motor in the fan device, and there will be an overheat circuit breaker in the motor. If there is a short circuit in the coil winding, the heat will increase for a short time, so that the motor will \"strike\" and not move.
4. The starting capacitance becomes smaller. When the fan is used for a long time, the capacitance will be reduced, resulting in the motor starting torque becoming smaller and unable to drive the load.
5, many times the cause of fan blades do not turn, is the problem of poor maintenance. If the blade is turned stiff by hand after the power is turned off, some lubricating oil should be dripped into the shaft so that it can be lubricated, so as not to affect the motor to drag the blade.
6, for the wear caused by the wind blade does not rotate, the simplest is to replace the parts, especially the shaft sleeve, if it is easy to burn after wear.
7, if the capacitance capacity is small cause the fan does not turn, you can remove the capacitor, change a new capacitor of the same model, it is recommended to choose 20% larger than the original capacitor, will have a better rotation effect.
one
The three lines separated from the fan capacitor are the yellow capacitor rotor control line to control the fan rotation, the red power line, and the blue neutral line.
two
Connect the blue cable of the fan to the rotor control cable of the capacitor, and connect the black cable to the power cable of the capacitor.
three
After the connection, the remaining red line is connected to the power supply, that is, the 220V live line, and then the remaining two lines are connected to the neutral line of the power supply with one of the lines, so that a loop can be formed, and the capacitor plays the role of starting the capacitor.
four
In this way, the capacitance of the fan is connected to the fan.
