How a series wound Golf cart motor goes in reverse.

In this video, I explain how a series wound electric motor can be wired to spin in different directions.
In the future, I will include a link to the video where I practically overview how to wire an electric vehicle or Golf Cart and forward and reverse.

Thank You Very Much for this wonderful illustration. Your description is excellent. We are restoring a 1982 Western cart.

Awesome!

[@WeThePeople-j2s]

I’m preparing to install a forward and reverse contactor in place of the old school switch this helped tremendously thanks

[@RetroElectric]

You are welcome. It is definitely a confusing concept that no Golf Cart schematics explain.

[@abnerschmucker1]

Thanks! Very helpful.

[@joelharper9379]

This is the best explanation of them all GOOD JOB TAHANKS very simple !

[@RetroElectric]

Thanks. It took me FOREVER to realize this! And NOTHING on UA-cam explains it!

[@Trevsrandomstuff]

Thank you! Please show us or draw a wiring diagram for the golf cart with 72v SPIM08HP battery, 200A throttle controller, pedal, and the BMS only used for charging.

Good lesson, thx

[@RetroElectric]

It was helpful when I learned it so hopefully it’s helpful to others

Nice thanks!

Your welcome

So I saw one where power goes into a1 comes out of a2 then hits 2 solenoids to only change the direction of the field connections. Will that work too?

[@RetroElectric]

That sounds more like a shunt motor not a series motor. A series motor all the current passes through all of the fields. The armature fields and the stater fields.
A shunt motor current passes through the armature field, and the stater field on the outside has two smaller wires going to it, and the controller varies the resistance in that field to change the speed of the motor. It also changes the polarity of that field to make the motor go backwards .

@@RetroElectric how can I tell if I have a series or shunt motor?

[@RetroElectric]

@@joshuadavis2062 a series, wound motor will say S1 s2 a1 a2 a shunt Motor will say a1 a2 f1 f2 and the F1 and F2 should have smaller terminals

[@joshuadavis2062]

@@RetroElectric ok I for sure have a series motor then. So for that do I just reverse the polarity on the whole motor or where would I reverse polarity at to go in reverse?

[@RetroElectric]

@@joshuadavis2062 yes I do believe changing the polarity of the field should work
