Hi all,
I need a new motor for my small 3 3/4" 'Corbett's' Lathe. the existing motor is a 1/3 HP single phase motor, 4-pole, so 1500rpm (or so).
Before the motor failed, it seemed to run the lathe well, though I did seem to use the higher gears more to get a fast enough speed to get a good finish.
I have access to 1 of 2 potential replacement motors at a good price. One is a 1/3hp 2-pole (3000rpm) unit and the other is a 1/2hp 4-pole (1500rpm).
So neither is a straight like for like replacement.
Would it be better to:
- Go for the (perhaps over powered for the size of the lathe..?) 1/2hp unit at the same speed as now…?
- Go for 1/3hp unit at double the current speed, but at the existing power…?
- neither and continue looking for an exact match for the current motor…?
I'd appreciate your thoughts..
Many thanks in advance
Paul
