IP engineering chassis not working

[Sylvian Tennant]

Hello again - after a while of leaving 16mm well done for practical reasons looking to return to it in the very near future. I have dug out an IP entering chassis for a project which had stalled about 3 years ago.

Unfortunately when trying it out the motor is not working. i've used new batteries (bought yesterday) and have had a look around the chassis. There is a bit of rust (which was apparent when it was working) and nothing is loose.

I've partially dismantled the motor from the chassis and both turn freely.

I haven't tried the motor on it's own yet nor any different batteries but nothing smells as if it's burnt out.

Have anyone else had this problem.

The chassis itself is the deluxe chassis made from plastic and I have fitted a manual speed controller to it.

The cheap motors that IP and others use are readily available form your local electronics shop for a couple of quid.

Hi

I agree with Brian, if the chassis turns over fine and new batteries don't make the motor turn then I would ditch the motor and get a new one.

Give Ivan at IP a call, he will sell you a motor and the gear needed, they are not expensive. If you can get the worm gear off then somewhere like CPC or Rapid Electronics or even Maplin will stock those motors.

Hope thats useful

Cheers

Hi chaps

Looks like you're not wrong, there was a tapping in the motor housing. when i looked further it looks like the brushes have come loose, gonna have a look in maplins today and see if i can get a replacement motor.

Just found something potentially suitable

Would this be okay, i've checked the dimensions and they look acceptable.
