Over all its a win win giving me a much more versatile speed range
īut because i have the step pulley's i can use them to keep the motor running fast enough to keep cool when i want super slow, and not have to worry about over speeding it to run at my lathes intended 2400 rpm top speed or over speeding it so much i need to worry about the bearings or frying the motor. hmm if i leave the belt on that pulley it will cover 99% of the work i do without slowing the motor down so far i have to worry about over heating it. gee it cant be to good to run the motor at 5 hertz or at 100 hertz to get that nothing to everything speed range, and i wonder how much power it loses when turning that slow. I giggled a little when i found i could go from about 5 rpm clear up to who knows what speed with just a turn of the dial. 750 rpm and played with the speed control. The first thing i did was to put the belt on the speed i used the most. Last night when i flipped the switch and turned it on. I think that is the wrong attitude, having the step pulley's with the vfd is a huge advantage i failed to see until I think most people who do this conversion do it with the mind to have the wonderful variable speed optionĪnd no longer have to deal with changing the belt. īut because i now have something you do not get with the g0752. not because its going to be cheaper by a few bucks for me. and have learned i made the right choice. įast forward 10 months or so and i now have most of the conversion finished. i was also somewhat sure i could convert it to 3 phase and a vfd for roughly the same money as the difference in price. I ended up going with the g0602 simply because i could afford it. Īnd a variable speed model the g0752 that i was unsure of due to not knowing the quality of the components used in the variable speed drive.
The g0602 with a somewhat limited speed range do to using a step pulley arrangement. Way back nearly a year ago when i had finally decided the grizzly 10x22 was almost exactly the perfect size lathe to suit my needs i found myself in another quandary, grizzly offered the lathe in two models.
