Recommended motors & gearing

[choochoo_baloo]

I am hoping that others may be able to recommend a particular supplier of 12V DC motors (of sufficient torque to open an observatory roof), and gears etc to produce a drive system. I'm happy to pay more for quality goods - as opposed to the various offerings from eBay and generic Google searches.

 

Thanks in advance.

I used this...................... http://www.easygates.co.uk/chamberlain-power-drive-gpd60.asp

The unit is 230V mains, but the motor is 24V DC it would probably have enough grunt running on 12V.

We use that kind of thing as well, even on the very big 4 scope shed.

For torquey 12v motors look into windscreen wiper motors. Cheap as chips from a scrap yard.

When we were kids my farther built for my brother a beautiful little car that ran on a 12v lead acid battery. The motor was a wiper motor from a Talbot Sunbeam and easily had enough power to carry a large adult.

An alternative may be a motor from a motobility scooter. Most are 24v, but I think some of the smaller ones are 12v.

A local scrap yard is asking ~ £30 for a Peugeot/Ford wiper motor. Does this seem reasonable to you?

That does sound a bit steep for a used WS motor to be honest. 

There's plenty on eBay, if you can find something local will save on postage
