Bridgeport Series 1 MDI Conversion

Hi Chaz,

Not sure if this helps you any.....

I chose these in the end. ( the Std SEM motors on mine were 3.2 NM. They worked pretty well too)

Physically much smaller than the SEM originals.

Shafts are same OD ad SEM, but a bit shorter, so I will probably have to make some custom timing pulleys with long spigot ( at least for Z axis anyway).

In hindsight, the 1.8KW version has a longer shaft and is still smaller than the SEM motors.

Regards

Mark

Thanks Mark.

They look identical to these and similar to what JazzCNC has reviewed.

Have you tried yours yet? I dont mind a bit of bracket modification, can do alu on my other mill but dont want to put major changes in if not needed.

Would you get the 1.8KW instead?
