How to reverse a motor using relay

how to reverse a motor using relay
I tried modifying this flipflop circuit, but i could use some input. The positive wire from the 9v battery will connect to both of the NO top inputs.

The Switch S1 and S2 control the relay 1 and relay 2 respectively.

Using Remote Control Relay to Control DC Motor Forward and Reverse

So, the motor terminals will have a positive polarity at the left side and a negative polarity at the right side. Thus, the motor turns in a clockwise direction. When two switches are open, both the relays are will be in a normally closed position. Which makes the ground or negative across the motor terminals, that is the same polarity on both sides.

Similarly, when both switches are closed here both terminals will have positive voltage the same polarity will obtain at two sides. On both conditions, the motor terminals are shorted and the motor brakes.

It is missing a stop button, start, and interlocks, and it can all be added to it. It doesn't start on it's own, one limit switch has to be pushed. The circuit has a dc motor, 2 relays, and 2 limit switches. The interlocks are important, because if the 2 relays are energized at the same time, it is a short circuit. As drawn, the whole circuit is on a same voltage relay coils would be same voltage as the motor. The bottom part can be separated, and then the motor can be a different voltage than the relay coils. Normally a circuit like this also uses additional overtravel limit switches, in case the two fail.

How a DC Motor Reversing Circuit Works Using Relays

A DC motor can run in either direction,by just reversing the polararity. If the motor draws a high current you HAVE to use relays,suitably rated for this.

The circuit I've shown is contolled by a simple 3 position switch. K that's the basics,let me know where you are from,and I will probably be able to comunicate in your native language.

Hi Ficticious, Please tell us a bit more about yourself,don't be shy.

May 21, Messages: Please help hello, i was reading this thread and found it very useful for the motor control that i wanted to build. I know this thread is pretty old but if anyone could please answer, i would be more than thankful. Dec 23, Messages: Eric's design was based on what the original poster had on their relay card. A single DPDT relay could be used very easily also.

Those H-bridges are very useful and smart, but if you just want to control the direction of the motor with a switch manuallythere is a much simpler and cheaper alternative. This little circuit is perfect for newbies. I've known this circuit for several years now, but I didn't got the idea of posting it until now. The parts, you need to make this can be found in any electronic store, or even lying around in your workshop if you have any.

DC motor direction control using relay circuit

A Double pole a. Forward, stop and backwards. A Power supply that suits the specs of the motor has the voltage and amperage as the manufacturer of the motor recommends.

How can I reverse polarity to a motor using relays?

In my case it was 2 AA batteries. A Batteryholder if you use batteries.

What are the green and silver items in the materials here? Also, is the circuit all soldered together? Apologies for stupid questions. JohnA author Reply Trackaround70 author Reply Simple yet effective, thanks?? Doctor author Reply Trackaround70 author Doctor Reply On this page http:
