How to wiring an electric fan motor? Wiring method of electric fan motor

1.Turn off the power first, and then read the manual in detail to distinguish the electricity. The function and purpose of the five wires on the machine.

2.Connect the three wires on the motor that control the wind speed to the gear of the switch. Terminal connection.

3.Connect the power cord on the motor with a socket switch, and there is only one left. root, just connect the capacitor.

4.When the power supply is turned on and the fan rotates normally, the wiring is successful. The red wire (live wire) and blue wire (neutral wire) of the four-wire fan motor are connected to the main coil of the motor, and both ends of the starting capacitor are connected to the red wire and gray wire at the same time.

The orange line and the red and gray wires are connected to the speed control switch respectively, the red line is connected to the high gear, the orange wire is connected to the middle gear, and the gray wire is connected to the low gear. However, some fan wires may be different in color. At this time, we need to use a multimeter to measure, find out the relationship between the coils, and then wire.

In general, the red wire (live wire) and blue wire (neutral wire) will be connected to the main coil of the motor, and one end of the starting capacitor will be connected to the live wire. Next, we have to think about which of the other two wires is connected to the starting capacitor. We can connect the blue wire (neutral wire) to one end of the ohmic file of the multimeter, and then use the other end of the multimeter to measure the two wire plugs of the secondary coil (i.e., the gray and orange wires in the diagram) in turn, and connect the wire with the highest resistance to the connection end of the starting capacitor.

The five-wire motor of the fan motor is a three-speed regulating motor.

For variable speed fans, variable speed switches should be added, and the wire ends at all places should be set as follows: the main winding wire ends of the motor (low impedance red, high impedance yellow, circuit black; The starting winding wire is connected to capacitor white and circuit blue); Plug two wires (green, zong);

Variable speed switch wire head (purple, blue);

Capacitor wire (gray, orange). The color of the quasi should be like this: a wire of the plug is connected to the incoming line of the speed control gear switch, and the three red, white and blue are one, two, three, three gears (as for which is fast and which is slow, according to the resistance value between it and the live wire, the resistance is small and fast), yellow + black capacitor + plug Another wire (starting coil).

Tools Raw Materials:Electric fan motor line.

1. The motor line of the electric fan is divided into black line, red line, white line, blue line, yellow line. The power cord is either one. Generally, the black wire is the main line of the motor.

The blue line is usually the switch of the electric fan. The red line is generally the fast gear. The white line is also a switch for the gear, and the blue line is also a switch for the unit.

2. The red line is connected to the first gear, the second gear of Nanxian Street, and then the white line is connected to the third gear, the yellow line on the gear is connected to the other end of the black wire of the capacitor, and the other end of the black line is connected to the main line plug, a section of yellow, and the green line, which is generally connected to the underground line.

3. The motor of the electric fan has a split wire, a neutral wire, and the general neutral line live wire is 220 volts, and there is a governor in the middle.

There are two windings inside the motor, one is the main winding, which is the running winding, and the other is the secondary winding, which is the starting winding.

The neutral line of the single-phase motor can be reversed, as shown in the figure above, the position of the live wire is changed, that is, the wires connected at both ends of the capacitor are changed, and the forward and reverse functions of the motor are realized.

As we can see from the above figure, when we put the multimeter resistance file and put the two meter pens at point A and point B respectively, the resistance value between AB is actually the result of the two winding strings of the starting winding and the running winding together, so the resistance value is the largest. A little smaller is the resistance of BC, that is, the resistance of the starting winding; The smallest is the resistance of AC, that is, the resistance of the running winding, and it satisfies AC+BC AB. (Most single-phase motors have less resistance than the secondary winding).

How the motor works.

As can be seen from the above figure, this circuit can be divided into three parts, the leftmost 220V AC circuit, the middle swing circuit, and the rightmost fan circuit. The electric fan motor is a single-phase AC motor, which has two windings inside, one is called the running winding (also known as the main winding), and the other becomes the starting winding (also known as the auxiliary winding).

The starting circuit consists of a split phase, so that the main and auxiliary windings are spaced 90° apart by an electrical angle. The speed regulation circuit is composed of a reactor speed regulating switch in series, and the voltage of the motor is changed to achieve speed regulation by adjusting the reactance size. After figuring out this circuit diagram, it is enough to repair the electric fan.

To do this, you must first figure out the winding, operation, assistance, and speed regulation of three sets of windings. Find the auxiliary capacitor and connect it to the auxiliary winding, and the other end of the capacitor is connected to the main winding and the 220V incoming wire (1).The other three wires are connected to the other power cord for the tap gear line, and you can know the weak medium and strong gear by trying them separately.

Six wire heads, one of which is grounded to communicate with the metal housing. The remaining five are used in the multimeter 10-1k ohm gear to measure the largest resistance value for string capacitors, and the remaining three are connected to the speed control switch, and one power cord is connected to the input end of the power switch, and one is connected to the capacitor side (pay attention to the forward and reverse rotation), turn on the power supply, and turn on the speed regulation, but it must be a normal motor (the maximum resistance is equal to the sum of other resistances).

Three-speed fan motor, in addition to the yellow and green wires, should have 5 wires (fast, medium, slow and capacitor ends), black, red, white, blue is only 4 wires, and 1 should be connected to the capacitor.

If the wiring is used according to the standard, the wiring diagram is as follows:

Red, white, and blue are connected to the gear selector switch respectively.

The motor line of the electric fan is mainly divided into black wire, red wire, white wire, blue wire, and the power cord is any one of them. The blue line is generally the switch of the electric fan, the red line is generally the fast gear, and the white line is a switch of the gear. The red wire is connected to the first gear, the blue wire is connected to the second gear, the white wire is connected to the third gear, the yellow wire is connected to the other end of the capacitance black wire, and the black wire is connected to the main plug.

1. The motor of the general electric fan is divided into live wire and neutral line, and the general zero line and live wire are used at home, and there will be a speed regulation in the middle of 220 volts.

2. During the use of the electric fan, if the button of the power supply is pressed and the fan does not rotate, you first need to check whether the fan power cord is aging or damaged, and replace the power cord with the risk of damage or aging to solve the problem.

3. If the electric fan is suddenly fast and slow during operation, it may be because the voltage in the family is insufficient and the fluctuation range is large, you can use a voltmeter to measure the voltage fluctuation and install a voltage regulator to stabilize the voltage. If the voltage is insufficient during peak hours, you need to contact the local power supply company to solve the power supply problem.

The coil colors of the three lines are red, black mountain pure, yellow three lines, and any one of the input lines is connected to the red line.

The other one is connected to either end of the black wire and the initiator to dissipate the capacitor, and the other end of the starting capacitor is connected to the yellow wire.

The coil colors of the five wires are red, white, blue, black, and yellow, and the connection method is basically the same.

The difference is that the red line is the first stop line, the white line is the second stop line, and the blue line is the third stop line.

One end of the power input terminal is connected to the main switching terminal of the gear, the other end is connected to either end of the black wire and the starting capacitor, and the yellow wire is connected to the other end of the starting capacitor.

If the above does not solve the problem, please try:

The coil colors of the three wires are red, black, and white.

The red wire is connected to the live wire, the black wire is connected to zero, and the white wire is connected to a wire of the capacitor.

The capacitor is another tease, a wire is connected to the red wire.

The wiring method of electric fans is generally divided into two types, one is that two wires are directly inserted into the plug, and the other is that it needs to be wired.

The wiring method is as follows:

1.First, peel off a section of insulation from the power cord and motor cord of the electric fan to expose the metal wire.

2.Wrap the metal wires of the power cord and the metal wires of the motor wire with insulating tape or insulating sleeve respectively to avoid short circuits.

3.The metal wire of the power cord and the metal wire of the motor wire are inserted into the corresponding holes of the power plug and the motor plug respectively, the two holes of the general power plug are the live wire and the neutral wire, and the two holes of the motor plug are the positive and negative poles.

4.After plugging in, tighten the screws on the plug with a quick screwdriver to fix the metal wire and avoid poor contact.

5.Finally, wrap the plug with insulating tape or insulating sleeve to prevent leakage or short circuit.

Notes:1Be sure to turn off the power before wiring to avoid electric shock.

2.When wiring, pay attention to the positive and negative poles of the power cord and the motor wire, as the reverse connection will cause the electric fan not to turn or turn in the opposite direction.

3.After wiring, check whether the plug is firm and whether the metal wire is in good contact to ensure safety.
