Where do the six binding posts of the three phase asynchronous motor come from

It's above the stator, the rotor has no wires, and the rotor is just a shell. 6 wires, I'll tell you how to connect.

1.Triangle connection - use three copper sheets to connect the three groups of joints in the vertical direction respectively, and then connect the three heads below to the three power supplies.

2.Star-shaped connection - use two copper sheets to connect the three binding posts in the upper row of the horizontal respectively, and then connect the three power supplies at the bottom three ends.

Connection method of three-phase asynchronous motor: most motors have six binding posts, some also have three binding posts, and three binding posts are star connections. There are six of them that need to be wired according to the connection method on the motor name plate.

Triangular joints: such as.

u1 v1 w1

U1 and W2 are connected, V1 and U2 are connected, W1 and V2 are connected to W2 U2 V2

Star connection: such as.

u1 v1 w1

Connect the head or end of the motor, e.g. U1 V1 W1 to U2 V2 W2

The above connections are all 380V three-phase asynchronous motor connections, if the three-phase asynchronous motor is controlled by frequency conversion, the star connection method is required.

These six terminal piles are the heads and tails of the three windings of the three-phase motor, which are the heads of these three windings, which is the tail of the windings, that is to say, and is a winding, according to what you said, connected to the power supply, then it should be shorted together

Not six binding posts.

The three-phase four-wire is the ABC three-phase and one neutral wire. The main function of the neutral line is to form a loop. The three binding posts of the motor are connected to the ABC three-phase, which is connected to a star-shaped or three-dimensional star.

I don't understand what you are talking about, connected to three-phase four-wire, the motor is connected to three binding posts, connected to ABC three-phase.

It is drawn from the coil pack inside the motor.

Three-phase motor 6 binding posts liberated:

The wiring board of the three-phase motor is generally 6 binding posts, 3 on the upper side and 3 on the lower side, assuming that the upper 3 binding posts are 123, then the lower 3 binding posts are 456 in turn. The star connection method is to short the 3 binding posts of 123 with a connecting piece, and the 3 binding posts of 456 are connected to the 3 phase wires of the three-phase power supply respectively. The neutral line does not need to be drawn out.

The angular connection method is to use 3 connecting pieces to short-circuit 1 and 4, 2 and 5, 3 and 6 respectively, and the three phase wires of the three-phase power supply are connected to 456 respectively. If it is a three-phase four-wire power supply, the neutral wire can be connected to the shell of the motor.

Direction of the three-phase motor:

Three-phase motor refers to when the three-phase stator winding of the motor, after the three-phase alternating current is introduced, a rotating magnetic field will be generated, the rotating magnetic field cuts the rotor winding, thereby generating an induced current in the rotor winding, and the current-carrying rotor conductor will produce electromagnetic force under the action of the stator rotating magnetic field, so as to form an electromagnetic torque on the motor shaft, drive the motor to rotate, and the motor rotation direction is the same as the direction of the rotating magnetic field.

An AC motor driven by a three-phase alternating current. Three-phase motor It refers to the three-phase stator winding of the motor, after the three-phase alternating current is introduced, a rotating magnetic field will be generated, and the rotating magnetic field will cut the rotor winding to generate electricity. It includes a three-phase synchronous motor and a three-phase asynchronous motor.

How to connect the 6 binding posts of the three-phase motor, the connection of the three-phase asynchronous motor: most motors have six binding posts, some also have three binding posts, and there are three binding posts for the star connection. There are six of them that need to be wired according to the connection method on the motor name plate.

Triangle connection: such as U1 V1 W1 and W2 connected, V1 and U2 connected, W1 and V2 connected W2 U2 V2 Star connection: such as U1 V1 W1 The head or end of the motor is connected, such as U1 V1 W1 is connected to U2 V2 W2 The above connections are 380V three-phase asynchronous motors If the three-phase asynchronous motor is controlled by frequency conversion, the star connection method is required.

Hope the above helps

The three wires out of the three-phase asynchronous motor are connected to the internal windings, and in principle, they cannot be regarded as interconnected. However, the three-phase motor has a large power and a large current, and in order to reduce the winding loss, the winding resistance is usually small (the motor resistance with enough power is generally milliohm or even microohm), and if it is measured with a multimeter, the result is interconnected.

Reasonable selection of power supply is one of the important measures for energy saving of asynchronous motors. Generally speaking, the power supply conditions should meet the requirements of the technical conditions of the motor. However, the current power supply conditions in China are not ideal, and the deviation between the power supply voltage and the rated voltage of the asynchronous motor is greater than 5%, which is not uncommon.

Some asynchronous motors (especially agricultural motors) run at -10% rated voltage deviation for many years, which not only increases the loss and wastes electricity, but also shortens the service life due to the increase in the temperature rise of the motor due to overcurrent. Every summer during the busy farming season, there is a "motor emergency" in various places, mostly because the power supply conditions do not meet the requirements.

The winding of the three-phase asynchronous motor can have two kinds of star connection or triangle connection, and if it is a star connection, there should also be a fourth common contact to form a three-phase four-wire system. In the case of a triangular connection, there are only three contacts. Therefore, it can be inferred that the motor is connected in a triangle.

In fact, no matter which connection method, any two of the three contacts are connected, but the resistance value will not be zero. And it should be equal, if the resistance value is too large, there is an open circuit, and if the resistance value is zero, there is a short circuit. Unequal resistance values also indicate a short circuit inside the windings due to poor insulation.

If only three wires come out, then the internal connection is open regardless of the star connection or the corner connection, and if 6 pieces come out, they are connected by two.

Summary. The six binding posts of a three-phase motor generally correspond to three phase wires and three neutral wires. Depending on the type of motor and the environment in which it is used, the wiring method may vary.

But usually, the binding posts can be connected as follows:1First, determine the supply voltage and frequency of the motor to ensure that the appropriate cable and connection configuration is selected.

2.Of the six binding posts, three look for the ones labeled"l1"、"l2"with"l3"of the columns, which correspond to the three phases of the supply voltage. 3.

The other three binding posts are marked"n1"、"n2"with"n3", which corresponds to the neutral line. 4.According to the specific wiring diagram of the motor, connect the corresponding phase wire and neutral wire to the corresponding binding post.

Make sure the connection is secure and use insulating tape or sleeve for insulation protection. It should be noted that motor wiring involves electrical knowledge and safety issues, if you are not familiar with or do not have professional technical knowledge, it is recommended to ask a professional electrician to carry out the wiring operation to ensure safety and correctness. Hope the above meets your needs, if you have more questions, please keep asking.

Can you tell us more about that?

The wiring of a three-phase motor usually includes six binding posts to connect three phase wires and three neutral wires. Depending on the type of motor and the environment in which it is used, the wiring method may vary. In general, you can connect as follows:

1.Determine the supply voltage and frequency, and select the appropriate cable and connection group megagram. 2.

Find the label labeled"l1"、"l2"with"l3"The ruler grinds the column as the three phase wire terminal points of the supply voltage. 3.Find the label labeled"n1"、"n2"with"n3"The column serves as a neutral terminal point for the Ling bucket.

4.According to the specific wiring diagram, connect the corresponding phase wire and neutral wire to the corresponding binding post and carry out insulation protection. Keep in mind that motor wiring requires technical expertise, and it is recommended to have a professional electrician operate it to ensure safety and correctness.

1.If there is an outgoing line identification in the junction box, skip this step and go directly to the second step. People stand at the tail end of the motor (the end of the heat dissipation impeller), use the low resistance of the multimeter to measure the resistance of each of the three wires in the left and right rows, determine the wire ends of the three groups of coils according to the conduction, and mark them according to U-R, V-S, W-T, both the left side is U, V, W, and the right side is R, S, and the star connection:

Connect R+S+T together, and connect U, V, and W to power supplies A, B, and C respectively. 3.Triangular joints:

Connect the three sets of coils end to end, that is, U+T, V+R, W+S, and then connect these three points to the a, b, and c items of the power supply respectively. 4.No matter what the above two connections are, if the direction of rotation of the motor is opposite to the requirement, just switch any two wires in the power cord.

Hope mine helps you! Hope.
