Topic: C5 Motor dead?

[C5 ENTHUSIAST + RESTORER]

Hi you can grease the bearings if you like but they where sealed and fitted from new .But if they are seized they will need replacing ...
Regarding the gear box I use a general purpose grease .

I took apart the motor and things don't look right.

I uploaded a video to youtube (3 minutes) where I ask a few questions and show all components.
You can see it here:  https://www.youtube.com/watch?v=J566y_JzjrU

These images are to show the slag on the armature that I talk about in the video.



Any advice or knowledge that can be passed is helpful, thanks.

Hi Adam just been on YouTube and looked at your video .as far as I can see the motor  has been overloaded and is is now burnt out it will be not be any use sorry
Regarding the thin washers they do go where you said the flat one on the bottom when you rebuild the motor up put some grease on them to keep them in place .
Next thing the gearbox is in good condition and should be as it is the reason for the shape is that when its in place the motor can be turned a little to tighten the belt when putting the motor check the key ways ..
Also the brushers seem to be ok but when you put them back make sure they are tight in place .as they where made to be fitted once .

Hi Adam,

before junking the motor, take the armature (the part that rotates) to a motor specialist and have them check the coils for short circuits, at the same time have the commutator surface (the copper segments at the end of the armature)  checked. If there are shorts it's a case for a replacement motor, unless someone is prepared to rewind it for a reasonable price. If the surface of the commutator is badly scratched have it cleaned.

There as a couple of points that have not been covered. Firstly, why did the motor end up in this condition? The motor has a thermal cutout fitted to the case, plus a thermistor, to measure the temperature, that is located within the armature. These are there to protect the motor from overheating.

It seems to me that these two items have been bypassed.

Assuming all is OK, it is imperative to have the thermal cutout mounted on the motor casing. You can do away with the thermistor, but it is advisable to have it fitted. The thermistor activates a warning signal on the Pod unit, indicating that the motor is starting to overheat.

Hope this is of some use to you.

Hi there as Karl has said someone must have bypassed the Sensors .
But  have the rotor checked out and let us know how much it would cost to rewind it as I do have a spare rotor so do not throw any thing away bye Chas

Chas / Karl,

Thanks for all the assistance on this.  I will locate a business to take the armature into next week as everyone is closed for thanksgiving.  I'll see if the part can be saved or rebuilt and will post back to the forum at the end of next week.  Thanks again for all the help.  Spirits are high still because of this forum .

Hi!
I took a similar size motor windings to a local re-winder recently. He did not repair such small motors but sent them away to Birmingham (UK) and suggested £120- was their normal price.

Hi Adam,

after reading Chas's post I would recommend buying the armature from him. The reason I recommend this is, even if the coils are not open or short circuit you can never be sure that it will hold out in the future. From the photos you posted, the thing looks like it is/was on it's last legs. Just think of the wasted time involved if all is reassembled and then, after a couple of miles or so, the motor packs up. Plus of course I should imagine the P&P for the armature would be far less than a complete motor.

After looking at the armature again, I think I agree.  Chas, If the offer is still there - I would greatly appreciate the opportunity.  Please let me know what you are looking for it and my zip code is 53959, Wisconsin in the US.  If you guys think the picture / Video looks bad, the armature in person is even worse.    I am also looking for front hub caps if anyone has an extra.

Hi Adam ok will send the rotor just need to check the p/packing will get back to you later for the total cost
Bye Chas

[C5 ENTHUSIAST + RESTORER]

Hi there Adam just checked the postage and it goes from £25.00 to £70 .00
That does not include ins ....

If you still want to go ahead can you give me your full posting details .
Also if you are going to scrap the old rotor before you do have some one take off the cog as they are very hard to find .
