Turntable motor.

I am at the stage when I am about to wire a Peco motor into my turntable. Can I pick up the power from the Bus Wire (about 15v) or do I need a separate supply?

If you are DCC I would say the answer is no to using the bus unless the turntable is fitted with a decoder.

Hi
You can use a DCC Loco decoder to power the TT motor feed from the DCC or use a variable DC supply often from an old DC train controller.
You cannot use the DCC power directly as this is a sort of AC power.
You will on DC ideally need some means of varying the rotation speed and change direction of rotation. Hence the suggestion of a train controller.

Thank you for your prompt replies.

A separate 12v supply it is.

Remember that your DC transformer needs to be a type of DC controller because you need to control the speed and direction of the turntable. (Wiring direct to a 12v DC transformer will make the turntable move at flat out speeds in one direction).
An old low powered trainset style controller is ideally suited for powering a turntable.

Some modern expensive turntables have the luxury of DCC and this is simple to wire as one takes link wires from the track (Whick come from the DCC controller) and if one wants to use DC instead, one simply powers it via a non-feedback type DC controller. (Must not be a feed back controller).

MG you have just repeated what Brian said regarding using an old controller.

Oh. Oops!

I have a DCC turntable now. It was a DC one, but i simply added a decoder, made it number 22, and wired it in. Now it works from both Railmaster, or Elite.

Ditto - fitted a decoder, gave it address 100 and RM runs it fine most of the time. If it gets out of synch with the screen. I simply use the Elite to manually drive it back into line again.
Edit - although I run RM I also run Trains-a-GoGo (TGG) which is much like RM but better and has loco detection and thus does what RM cannot, sensor triggered event sequenced programs, rather than timed event programs. TGG was written by a Hornby forum member out of sheer frustration waiting 8 years for Hornby LD to launch.

Being a complete novice to this DCC and the world of decoders, which decoder would I need to control my Peco motor driven turntable, I am using a Hornby Select controller?

Thank you
