Lathe Drive Motors, 1ph or 3ph?

| 1058 forum posts 16 photos | Having run my lathe (a Warco WMT300) on both single and 3 phase motors, I can quite confidently say that there is absolutely no difference in the quality of surface finish. The advantage of running a 3 phase motor on a a VFD is quite simply the ability to adjust speed at the touch of a button, although, I do change drive belst settings to get really low speeds as running any motor at low speed will cause overheating issues. I also have an auxilliary cooling fan on the motor to cover such eventualities. Unless your motor is very badly mounted, there should be no difference in surface finish between single and 3 phase motor drive. Be very wary of the temptation to run any 3 phase motor at increased frequency unless specifically rated for such operation. Most 'common' 3 phase motors will not run well at higher frequencies. |
