testing motors , how a wire it up to a 13amp plug..

[razor]

trying to setup a test lead to plug in motors to test them

anyone know which wires a use to stick a plug on it to test they run

motors –

hotpoint wm62 and indesit wg1234t

probs will have more motors to test aswell ,

thanks all

This is how I do it:

Live -> Field coil -> Other end of field coil (link to) -> carbon brush then the other carbon brush -> Neutral

The only problem is that many motors now have various taps to the field coil so it’s not always easy to work out which one’s to connect to 😉

Razor,

I firmly believe if you are thinking of setting up a reconditioning service for Hotpoint/Indesit/Zanussi motors etc. It would be far better to set up a test rig that includes the relevant control modules for each type. That then enables you to carry out low speed/controlled speed testing. 💡

Simply plugging them into a 240 volt supply will not be sufficient but it would at least create a wonderful firework display I suppose. 😆

that probs be better idea Martin

think we will just have few machines sitting just for testing the motors
as u said to check the dif speeds.

cheers

I’ve always put the live through brushes first but I’m not sure why ❓
I suspect this is the way it is on the machine at spin. I think the triac is on neutral side normally. ❓

It doesn’t really matter which way it’s done, it’ll work either way.

As Martin says though, it’s not an ideal solution as it only checks full spin, I’ve checked Hotpoint motors before like this only to find the armature fails when tumbling under load even though they spin perfectly.

thanks all for the replys

do the right thing , stripped out all the wiring for the hotpoint including timer , module bypassed door interlock , first 1 up and running 🙂

couple indesits and zanussi’s next

all these motors work in the same way as a series wound motor suggest you put a load in series for initial test this can be as low as a 100w lamp of use a grill element thus if you have a short circuit either to earth or the like you will not get a big bang. it will also calm down the initial start torque. after the motor is running you can switch out the load. i used this method to recondition the ols ac and dc modules and motors from the older hoover autos

If you apply a bit of pressure to the motor pulley with a lump of wood when it’s running at lowest speed that will tell you whether it’s giving enough torque to turn a drumfull. (You need to be sure of your test rig though). Don’t leave the lump of wood there too long or it will catch fire,just like on a Ray Mears programme.
