How to control the forward and reverse rotation of a single phase motor with a button?

Single-phase asynchronous motor is divided into: capacitor start, capacitive type and shaded pole type, capacitor start type and capacitive type can realize the forward and reverse rotation control of the motor, and changing the forward and reverse rotation of the motor is to change the direction of the rotating magnetic field of the motor to achieve.

This can be achieved by adjusting one end of the wiring of the winding of the capacitor connected in series to the other end of the power supply.

The principle is that the current in the capacitor circuit is 90 degrees ahead of the voltage. The shaded pole type cannot be reversed, and the connector of the main coil and the coil of the capacitor phase separation can be swapped for the capacitor operation type.

First of all, I have a question: there are two buttons, and there are a total of 4 normally open contacts inside, two by two, and a group of two is side-by-side, and if you press any button, then all 4 points are in the ON state This doesn't seem right, right? Pressing any one of them should be 2 contacts turned on, that is, a group of contacts turned on, how can 4 contacts be turned on at the same time?

Also, I'll give you an example: you're driving forward, and all of a sudden you put it in reverse gear, will the car immediately back away? Do you have to stop before you can reverse?

Friend, this is obviously because the reversed button switch contacts in this button switch are burned out, or the wire contact is poor. It may also be that the line is not connected.

It should be to wait for the motor to stop and then press the reverse button, otherwise the motor will rotate in the positive direction, and it is easy to burn out the starting coil or capacitor, and it may be that the reverse button contact is less broken.

Check whether the motor bearing is broken, and check whether the power supply is normal? Disassemble the motor to see if it is normal or you reverse it with your hand to see if it is normal!

Check whether the motor is broken bearing, disassemble the motor to take a look, or you reverse it by hand to check if it is normal!

Hello dear and happy to answer your <>

Find a way to forward and reverse the single-phase motor for you1, how to adjust the positive and negative of the single-phase motor**The starting winding of the single-phase motor is connected in series with a suitable capacitor, and the two windings of the stator can be automatically rotated with the help of the phase-shifting capacitor.

In order to change the steering of the motor, it is necessary to find the starting winding at the contact point of the motor winding lead-out wire, and the one end of the original series capacitor and the other end of the original common point can be adjusted and connected to achieve the purpose of changing the steering. 2. Single-phase motor generally refers to a low-power single-phase asynchronous motor powered by a single-phase AC power supply (AC220V). This type of motor usually has a two-phase winding on the stator, and the rotor is a normal squirrel cage type.

The distribution of the two-phase windings on the stator and the power supply can produce different starting and running characteristics. I hope this service can help you, you can click on my avatar to follow me, and if you have any questions in the future, you can consult me again, and look forward to serving you again. Wishing you well; Happy life, everything goes well [warm] [warm].

There are two windings of the single-phase motor, one is the main winding, and the head and tail of the main winding are connected to the live wire and the neutral wire respectively. The other is the secondary winding, the resistor-started secondary winding, which is connected in parallel with the main winding by connecting it in series with the centrifugal switch, and needs to be reversed, just connect the head and tail of the secondary winding. The head and tail of the capacitor-activated trapped subwinding are connected in series with a series capacitor and then a series centrifugal switch.

Capacitive operated with no centrifugal switch.

Hello, I have a general understanding of the question you asked, and I am sorting out the answer, please wait patiently Hello, you can connect the two pins of the starting capacitor of the motor to the upper and lower interfaces of the switch with wires, and I will give you a schematic diagram.

Summary. Hello, now I have been sorting out the answer for you non-stop, and I will reply to you within 10 minutes, thank you.

<>1. Single-phase motor generally refers to a low-power single-phase asynchronous motor powered by a single-phase AC power supply. Single-phase motor has two coils, three heads, one end of the two coils is connected together as a head (common end), a starting coil is a head, a running coil is a head, the starting capacitor is connected between the lead running coil and the starting coil, the power supply is connected to the common end and the running coil when the motor is rotated, and the power supply is connected to the common end and the starting coil when the motor is reversed. By changing the connection method of the capacitor with a switch or blind relay, the forward and reverse rotation of the single-phase motor can be realized.

2. For the forward and reverse rotation of the three-phase motor, it is only necessary to change the wiring position of the three power cords of the three-phase motor.

The single-phase motor has two coils, three wire heads are clustered, one end of the two coils is connected together as a wire head (common end), a starting coil is a wire head, a running coil is a wire head, and the starting capacitor is connected between the running coil and the starting coil.

The forward and reverse rotation control of the one-way motor is as follows:

1. The motor rotates forward when the power supply is connected to the common end and the collapsed cherry coil is running;

2. When the power supply is connected to the common end and the starting coil, the motor is reversed;

3. Use a switch or relay to change the connection of the capacitor, and the forward and reverse rotation of the single-phase motor can be realized.
