The winch brakes the solenoid coil voltage 380V and has two wires, how to wiring it.

Electromagnetic switch wiring method.

1. Generally, the three-phase contactor has a total of 8 points, three inputs, three outputs, and two control points. The output and input are corresponding, and it is easy to see. If you want to add self-locking, you also need to connect the wire from one of the terminals at the output point to the control point.

Once you know the principle, you should figure out the contacts of the external power supply, that is, the two contacts of the coil, which are generally at the lower part of the contactor, and on each side. The other inputs and outputs are generally in the upper part, and you can see it at a glance. Also pay attention to the voltage of the external power supply (220V or 380V), which is generally marked as yes.

And pay attention to whether the contact point is normally closed or normally open. If there is a self-locking control, it is enough to sort out the line according to the principle.

Principle: When the coil is energized, the static iron core generates electromagnetic attraction and engages the moving iron core. Since the contact system is linked with the moving iron, the moving iron core drives the three moving contacts to act at the same time, and the main contact is closed.

The auxiliary normally closed contact, which is mechanically connected to the main contact, is disconnected and the auxiliary normally open contact is closed, thus switching on the power supply. When the coil is de-energized, the suction disappears, and the linkage part of the moving core is separated by the reaction force of the spring, so that the main contact is disconnected, and the auxiliary normally closed contact mechanically connected to the main contact is closed, and the auxiliary normally open contact is disconnected, so as to cut off the power supply.

Wiring method of three-phase asynchronous motor.

The three-phase stator winding of the three-phase motor has two lead-out wires for each group of windings, one end is called the first end, and the other end is called the end. It is specified that the head end of the first phase winding is represented by d1. The ends are denoted by d4; The first end of the second phase winding is represented by d2, and the end is represented by d5; The first and last ends of the third phase winding are denoted by d3 and d6 respectively.

These six lead wires are introduced into the binding post of the junction box, and the binding post is marked with the mark of D1 D6 accordingly, and the six ends of the three-phase stator winding can be connected into a star (connected to 380V) or a triangle (connected to 220V).The star connection method is to connect the ends of the three-phase windings in parallel, that is, the three binding posts of D4, D5 and D6 are connected together with copper sheets, and the first end of the three-phase winding is connected to the three-phase AC power supply respectively, that is, D1, D2 and D3 are connected to the A, B, and C phases power supply respectively.

The triangle connection method is to connect the first end of the first phase winding D1 with the end of the third phase winding D6, and then connect the one-phase power supply; The first end d2 of the second phase winding is connected with the end d4 of the first phase winding, and then connected to the two-phase power supply; The first end of the third phase winding D3 is connected with the end of the second phase winding D5, and then connected to the three-phase power supply. That is, D1 and D6, D2 and D4, D3 and D5 are connected with copper sheets on the binding post, and then connected to the three-phase power supply respectively.

The winch brakes the solenoid coil voltage 38

The winch brake solenoid coil voltage 380V has two wires, how to wiring.

Hello, I am glad to answer for you, the winch brake electromagnet shouts rock so that the coil voltage 380V has two wires, in this case, generally speaking, one of the wires is the power line (L1 phase wire), the other wire is the jujube bridge wire (N line), the power line needs to be connected to the phase line of the power supply, and the neutral wire is connected to the neutral line of the power supply. The wiring method of the Zheng bureau body is as follows:1

First, determine the phase and neutral wires of the winch power supply, which can be detected by using an electric meter; 2.The two wires of the winch solenoid coil are connected with the corresponding wires of the power supply, under normal circumstances, the power cord needs to be connected to one terminal of the electromagnet coil, and the neutral wire is connected to the other terminal; 3.After confirming that the wiring is correct, carry out the power connection test to check whether the winch solenoid is working normally.
