So for a single phase replacement, a 2 pole 2840-3000RPM, TEFC
motor with suitable shaft which fits the pulley, seems like it might be one choice?
Can we see the mounting, as it could be foot, face or flange mounted, should one want an quicker or less bothersome installation.
On the other hand if Geoffo wants to retain the function for cutting differing materials...
and sees some dual voltage motors going cheap...
Which pole motor should be used, from what I've seen on different machines, a 4 pole slower motor seems the choice for most things not a fixed speed.
Whats the issue if one chose to run a 4 pole motor (around half the speed of 2 pole)
with an inverter at 100hz?
Is there some torque issues at double the rated speed of the motor?
Is this an application for having a fancier vector drive?
