Power Supply for Parvalux Motor

Hi all,

I have just bought this small Parvalux motor for Ebay to try to use as a power up & own on the head of my Warco WM18 Mill.

The specs of the unit are:

Details
1440 RPM motor (at 24vDC)
40 RPM at output (at 24v)
will run on 12v (approx 20 rpm)
40 watt,
Gearbox Parvalux worm and wheel 2.81 Nm

Approx 60mm diameter rubber drive wheel on a 8mm shaft.

Does the 'panel' think that this is going to be suitable for my anticipated use?

I had a look at the 24V power supplies on eBay and was completely boggled by the vast number available. I know very little about electrics and wonder which would be the best thing to get. It would be great if there was a dual 12V/24 unit as I could use the 12V for other things also. Would it work as a charger for small batteries (12V) and for a small electrolysis unit?

Could the unit run the up and down on the mill at 2 speeds by switching voltage?

Given my lack of know how here should I leave well alone and get someone in to do this?

Really just trying this as I am chuffed to bits with the x axis power feed I just did using Ian Parkin's help and great idea.

Cheers, Martin

Hi Martin,
I would avoid switch mode power supplies (Unless you over rate it to deal with any starting surge) If you want dual voltage I suggest using a 12 – 0 – 12 2 amp (Or larger ) transformer and a bridge rectifier. No smoothing or regulation is needed. Weather you can change the speed by varying the voltage depends on the type of motor. (permanent magnet, shunt or series wound.) I suggest using a piece of string wrapped round the Z axis handle and a spring balance to find out what torque is required to raise the head to see if the motor is suitable.

Martin this will do fine

from the list 24v 100watt

And you need a switch like this

thats a dpdt on -off-on

I can send you a diagram of how to wire it
