Hi,
Thinking about putting a lathe like a Colchester 13" on a VFD. I'm familiar with setting up this type of machine with true VFD start/stop, as my current lathe (Kent TRL) is setup that way.
On the true clausing colchester, the motor would always be running at full 60hz frequency, but then the "matrix clutch" would engage to quickly start and stop the spindle.
I suspect this would be OK, but the motor (5hp 1800rpm or so) would be very lightly loaded until the clutch engages, and then have the torque load to accelerate the entire geartrain, spindle and part to full speed. Presumably the clutch would mediate this power transfer somewhat, so it wouldn't be instantaneous.
To be clear I'd be using a good quality drive, Yaskawa probably. Something appropriately sized for the load but hopefully not need to be oversized.
