This is good to recognize that there are two connecting pieces on the binding post, and these two connecting pieces are connected to the forward and reverse rotation of the motor.
Yes, the power cord is connected to these two connecting tabs. The double capacitor motor feels powerless, and there are many reasons for the sound: one is that the motor is broken, and the other is that the main and auxiliary coils or capacitor wiring are loose.
Expansion: 1. Introduction:
An electric motor converts electrical energy into mechanical energy.
A piece of equipment. It uses an energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel cage closed aluminum frame) to form a magnetoelectric dynamic rotational torque. Motors are divided into DC motors, AC motors, and power systems according to the different power sources used.
Most of the motors in China are AC motors, which can be synchronous motors or asynchronous motors.
The stator magnetic field speed of the motor is not synchronized with the rotor rotation speed). The motor is mainly composed of a stator and a rotor, and the direction of the energized wire in the magnetic field is the direction of the current and the magnetic inductance line.
magnetic field direction). The working principle of the motor is the effect of the magnetic field on the current force, which makes the motor rotate.
2. Brief introduction.
An electric motor is a rotating electric machine that converts electrical energy into mechanical energy, and it mainly consists of an electromagnet that is used to generate a magnetic field.
windings or distributed stator windings and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, there is an electric current passing through the effective side of the stator winding and being rotated by the magnetic field. According to the principle of reversibility of the motor, if the motor does not change in its structure, the motor is used as a motor and can also be used as a generator.
It is a machine that converts electrical energy into mechanical energy. Usually the work part of the motor is rotated, and this kind of motor is called a rotor motor; There are also those that do linear motion, which are called linear motors.
The power that an electric motor can provide is in the range of milliwatts to kilowatts. Machine tools and water pumps need to be driven by motors; Electric locomotives and elevators require electric motor traction. Electric fans in family life.
Refrigerators, washing machines, and even all kinds of electric motor toys are inseparable from electric motors. Electric motors have been used in all aspects of modern social life.
The working principle of an electric motor: an energized wire is subjected to a force in a magnetic field.

Oh, the 5 wires out of the single-phase dual-value capacitor motor are U1, U2 (both ends of the main winding), Z1, Z2 (both ends of the secondary winding) and V1 (centrifugal switch end); U1 is connected to V1 and then connected to the live line, U2 is connected to Z2 and then connected to the neutral line (the more one does not care about it).

The wiring method of double capacitor of single-phase motor is:
1. The running capacitor line and the starting capacitor line are connected in parallel at one end of the secondary winding.
2. The remaining wire head of the starting capacitor is connected to the centrifugal switch wire head.
3. The remaining connecting wires of the switch and the remaining connecting wires of the running capacitor should be connected to the power supply line in parallel with the main winding after parallel connection.
4. The connecting wires of the remaining main winding and auxiliary winding are connected to another power cable.
5. Remove the insulation layer when connecting the winding wire.
6. To rotate the motor in the opposite direction, the two power lines of the main winding need to be reversed, and the motor can be rotated in the opposite direction.
Single-phase electric motors
An asynchronous motor with a single-phase AC power supply is called a single-phase motor. Single-phase motor is easy to use, widely used, and has the advantages of simple structure, low cost, low noise, and small interference to the radio system, so it is commonly used in household appliances and small power machinery with little power.
Such as electric fans, washing machines, refrigerators, air conditioners, range hoods, electric drills, medical equipment, small fans and household water pumps. Since China's single-phase voltage is 220V, while foreign single-phase voltages such as the United States 120V, Japan 100V, Germany, Britain and France 230V, so when using foreign single-phase motors, it is necessary to pay attention to whether the rated voltage of the motor is the same as the power supply voltage.

The wiring steps of the single-phase dual-value capacitor asynchronous motor are as follows:1There are 6 common binding posts on the chassis, which are:
Two pins of the main winding, two pins of the secondary winding, and two pins of the centrifugal switch. The main winding is connected to 220V; The secondary winding is connected in parallel with the main winding after the capacitor runs in series; After activating the capacitor series centrifugal switch, it is connected in parallel with the operating capacitor. For example, the main winding resistance of the motor is 1; Sub winding 2; Centrifugal switch 0 can be measured and distinguished with a multimeter.

Summary. Wiring method: 1. Connect the two contacts of the single-phase capacitor to the you and V ends of the asynchronous motor; 2. Connect the two contacts of the double-value capacitor to the W and V ends of the asynchronous motor; 3. Connect the power wiring to the you and w ends of the asynchronous motor.
Wiring method: 1. Connect the two contacts of the single-phase capacitor to the you and V ends of the asynchronous motor; 2. Connect the two contacts of the double-value potato capacitor to the W and V terminals of the asynchronous motor; 3. Connect several rounds of power wiring to the you and W ends of the asynchronous motor.
1. The wiring of the capacitive asynchronous motor needs to be connected to the three-phase AC power supply like a round of liquid, and the blind object can be connected to the single-phase power supply, otherwise the motor will be damaged. 2. When the capacitance value is single-phase capacitance, the single-phase capacitor asynchronous motor only needs to be connected to two wires, one is the U phase and the other is the V phase, and the W phase is not required, otherwise the motor will be damaged. 3. When the capacitance value is a double value capacitance, you need to connect three wires, which are U, Shensong V, and W phases, and when wiring, you should pay attention to the correct wiring of the capacitance value, otherwise the motor will be overloaded.
4. The wiring of the capacitive asynchronous motor should be completed in accordance with the correct wiring diagram, and the wiring method should not be changed by yourself, otherwise it may cause damage to the motor.
May I ask if this is ** connected wrongly, there is no force after powering on, and the wire behind is heated and burned.
If the capacitor asynchronous electric land type machine has no force, and the wire behind the wire is heated and burned, it is said that the circuit connection of the motor is wrong, it may be that the two poles of the junction box are reversed.
Do you see if it's reversed? Kiss.
The two thick red ones are the incoming threads, please help me see how to pick them up.
Pro, the two red incoming wires should be connected to the single end of the capacitor, while the other end should be connected to the phase wire and both ends.

Single-phase motor with single capacitor is the simplest and most basic motor. Of course, you have to understand first. Single-phase motor has two windings, that is, two enameled wires are wound, so it is called winding, two wires have 4 heads, one with two ends, and two ends are together, so you see that the motor will produce three wires.
In the case of not knowing which one hits which one, use a multimeter to measure their resistance in pairs, the largest two are connected to the capacitor, the remaining one is the common end, and the common is the two together. Comparing the resistance value, the larger one is the starting winding, connecting the power cord to the starting one is forward rotation, connecting it to the running winding is reverse rotation, and one of the common termination power supplies is needless to say.

Usually there will be a wiring diagram of the motor in the motor junction box, and the construction will be carried out according to the drawing. Single-phase motors are usually connected in series with the capacitor after connecting the two windings in series, and the single-phase power supply is connected to both ends of one of the windings, and if it is connected to both ends of the other winding, it is turned in the opposite direction.

Good morning, dear, and I'm honored to answer your <>
The method of connecting the single-phase double-tracer capacitor motor is: two capacitors are connected in parallel, one capacitor is connected in the main coil, and the other capacitor is connected in the auxiliary coil, so that the normal operation of the single-phase power supply drive motor can be realized. Attention needs to be paid to the wiring sequence, and the Xiangzhou bucket position of the main coil and the auxiliary coil should be reversed, so that the rotating magnetic field can be generated to make the motor run normally.
Due to the different capacitance values of the capacitors, the motor can have the same performance under different loads, which improves the adaptability and stability of the motor. In addition, the single-phase dual-value capacitor motor can also adjust the speed of the motor by adjusting the capacitance value. When the capacitance value is large, the starting torque of the motor is larger, but the speed is lower; When the capacitance value is small, the starting torque of the motor is smaller, but the rotational speed is higher.
Therefore, by adjusting the capacitance value, the motor can achieve the best performance under different loads. It should be noted that the single-phase dual-value capacitor motor needs to pay attention to maintenance and maintenance during use to avoid capacitor aging and damage, which will affect the service life and performance of the motor.

First of all, use a multimeter to distinguish the main and secondary windings of a single-phase motor, generally the secondary winding with a large resistance value is the secondary winding, and the main winding with a small resistance value. 2.Under normal circumstances, the main winding is connected to the U1 and U2 ends of the outlet box, the secondary winding is connected to the Z1 and Z2 ends of the outlet box, and the centrifugal switch is connected to the V1 and V2 ends of the outlet box 3
For detailed wiring methods, you can refer to the following schematic diagram for wiring.

Single-phase dual-value capacitor motor power line connection. How to connect the four wires?
1. Connect one of the large capacitors in series with the one head of the centrifugal switch. 2. Connect one end of another small capacitor and one short end of a large capacitor as the No. 3 terminal. 3. Connect the other head of the small capacitor with one head of the starting winding and the other head of the centrifugal switch.
Fourth, the other head of the winding that will be started is the No. 4 terminal. Fifth, the two wire ends of the main winding are set to the two terminals of No. 1 and No. 2 respectively. After the large and small capacitors are connected to the centrifugal switch, they can be energized after careful checking.
The motor is ** connecting No. 3 and No. 2 terminals to the phase wire, and No. 1 and No. 4 connecting to the neutral line. Motor anti**
Connect No. 2 and No. 4 in parallel; Line 1 and Line 3 are connected to the zero line. You can't go wrong by following this step. The key is to find the main winding and starting winding, and use a multimeter to check the pile head of the motor mark.
The function of the capacitor is to split the phase, that is, to turn one phase into two phases, and the angle is less than 90 degrees. In this way, the two-phase winding will produce a rotating magnetic field, and the rotor will rotate.
The total capacitance of the two capacitors in series is generally known, i.e., c=c1*c2 (c1+c2). >>>More
