Many thanks for the replys,

I've seen that 3/4hp single phase or 1/2hp three phase were the original specs.

Just had a look on newton tesla's website and they do a good selection of 1/2hp motors in 56 mounts.

I like the look of http://www.newton-tesla.co.uk/product/0-37kw-1-2hp-220v-415v-three-phase-4-pole-drip-proof-resilient-base/

I understand that it is not fully enclosed so I will have to protect it against coolant etc, will it have a cooling fan built in?

Many thanks,

Nick

Hello! Long-time lurker, first time poster!

I'm a complete newbie to motors when it comes to ratings and frame sizes etc so please excuse any stupid questions!

I've had my super 7 a few months now, it came with a Clarke 1hp single phase motor which sounds like a knackered 2-stroke engine, vibrates like nuts, runs very hot and is making the machine un-pleasant to use basically.

I’ve been given a 1/2hp VFD and would like to buy a motor to replace the clarke that I can use with this inverter.

My problem is I know nothing about motor frame sizes etc. The clarke seems to me to be a B3 80 frame foot mount, 100x125mm foot print with 19mm shaft. The problem is I can’t find any 1/2hp three phase motors in this frame size. Whenever I look at motors which are advertised at direct mount for Myfords they are described as B56, I’ve looked at the dimensions for this but none seem to match the clarke that I have now.

I’m on a budget so the easy option of buying a 1hp motor/VFD package isn’t open to me.

What size motor should I be able to fit? The motor plate on the lathe has not been re-drilled or anything, and everything looks standard.

Cheers,

Nick
