Not without pulling the windings to make it run on 220v

Hello Bsmith,

you can buy 240v 1 phase to 415 v 3 phase drives but at a higher price.

Well, yes and no. It can be ran with a 415volt VFD but I suspect what you are asking is "Can this motor run off a 240volt VFD"? and the answer is no.
However if you get someione to pull the points outof the wiring then you could run it 220 volts*


*someone far better able than I will be along shortly to explain.

Well no, no yes. You can run it on 240vsd, as @not done it yet says it will be on reduced torque, or reduced speed. I run a 4.5 kW mill on 240v, just haven't got around to pulling the windings yet.

Do you have a link to the vfd you were thinking of?

Ahh ok thanks fellas. My boxford lathe has a 1+1/2 hp single phase motor, it struggles a bit when turning bigger dia stuff. Thought if I got a 2hp, 3 phase motor and a vfd it would be powerful enough for all. I also believe 3 phase is smoother running and I like the speed control on vfd.

I have two of those topshak vfd's. Can't fault em.

 

[Bsmith]

So, to do what I would like I would need a 2hp, 220v 3phase motor and a vfd? Would I be ok with them?

In essence yes. Choose a motor with the mounting option to suit your application. If using a cheaper vfd rate it slightly higher than required. I have two lathes and a mill all running off vfd's (there are posts on the forum showing mine and a few vids on my YouTube channel).

1.5hp is a good match for a Boxford. Are you sure that it's not belt slip? What do you call 'bigger stuff' ?

a 1 hp quality old english motor will be fine/ if not a foreign or a clark 1,5 hp

The challenge is if the motor shaft diameter is different to the existing one. The drive pulley will not then fit the new motor and you cannot put it in the lathe to alter its bore as it is coming off the old motor that is driving the lathe. The solution is obvious: never own only one lathe.

or have a mate or brother that has one

6 - 8" dia I also find the lathe heavy to start in cold weather especially when using the gear train. Maybe the motor does not provide the power it is plated to do. It was one of the cheaper £Bay motors. If I remember right I think the original motor was 1hp 415v.

Changed motors once or twice before so have 2 pulleys.

A 6-8" part is a large piece for a Boxford to turn. You will do well to turn it in back gear.

 

[Seadog]

Pete's right. It's pushing it to the limit. I have no problems taking heavy cuts on around 4" material and only have a 1hp motor.

 

[Bsmith]

Yes i agree fellas, but when you need the job done and you only have the boxford.......
Photo shows one of the first motors I had on, it ran too fast for screw cutting.

Your back gear lever is in a strange position
