29 forum posts 2 photos | Hi hope someone can help, i have finally built a workshop ( after 20 odd years without one) and have been rebuilding my warco 220 lathe which was carefully stored away. unfortunatly i can not find the motor, obviously i put it away too carefully. I have contacted warco and they were very helpfull in supplying details of the motor and where i can get one from, sadly this option is very expensive, probably about £300 in all, does any one have any ideas about a cheaper option? thanks in advance Dave | ||

![]() 1531 forum posts 44 photos | Hi, Not so much an idea about where to obtain a replacement motor, but more an idea about what to get - if you see what I mean. I can't remember what the nominal speed is of the existing motor, but if possible, how about a 2-speed motor - one speed being the normal speed, with the other being a slower speed. This would then allow for a reduction in the minimum speed of 125rpm which would make screwcutting under power easier. Alternatively, how about going 3-phase, apparently much smoother and can also have variable speed along with a jog facility. Or finally, go DC along the lines of other lathes and milling machines, eg my MiniMill has a 500W DC motor - the 220 has a 550W AC motor so not much difference there in power but can be speed controlled. Apparently the Seig or equivalent controllers, and I assume motors, are available as spares. In fact, a combination of speed control and the existing belt arrangement would mean that the actual speed control range could be limited which would simplify the control arrangements and would not result in as much torque loss. As you may gather, I have a 220 lathe and the possibility of achieving a lower speed range down to say 15rpm or so has long intrigued me. As I say, just some random thoughts. Regards, Peter G.

533 forum posts | Dave, For not that much more than £300 you could buy a 3-phase motor and a VFD, and you would find that was very much better than a 1-phase motor. David | ||

Apparently the Seig or equivalent controllers, and I assume motors, are available as spares. Peter, He will be better off going down the 3-phase motor and invertor route. Using the normal brushed motor with SIEG controller for a differnt application is not advisable. they are better suited 'as spares" to replace exisiting SIEG breakdowns. The same applies to the brushless motor with SIEG controller, even though it has higher torque than the brushed versions. Also, the brushless option would work out dearer than the 3-phase motor and invertor option. May be good idea for David O to discuss with Transwave, unless WARCO already asked him to do this.

![]() 1531 forum posts 44 photos | Hi Ketan, As I said, just some random thoughts to consider if having tosource a new motor. Certanly if my motor failed, I would look at alternatives along the converter/3-phase line. Regards, Peter G, Shaw

From Machine Mart just check the spindle dia or bore out existing. | ||

![]() 6137 forum posts 893 photos | Drummond Lathe I bought a modern sealed motor but it ran very hot when the going got tough, especially if I was doing hours of backgear work So I retro fitted the old scroggy chunky electric motor which came with it when I originally picked the lathe up and it's been great This sort of thing They are really built to "last forever", like your mums old Hoover or a Singer sewing machine 2c | ||

For £250 I'll help you look for it Neil |
