My Whitcomb Blaisdell planer came with a wonderful old 1919 time frame *"Kelley Electric Machine Company" "Powerfloater" motor. The front end of the motor incorporates a planetary gear (reduction) drive on which is hung a huge triple cone for 4" wide flat belts.
The planer was run on the highest belt speed, and apparently that might still have been a little slow according to the guy who last ran it.
I have the (non drive) end bell off to bring out new leads due to the insulation crumbling off the old ones where they came through the motor side. The motor did run fine, until I moved the mass of friction taped wire to re-locate the greensleeve it was taped and routed into. Once the ball of tape was moved over, it crumbled all the insulation at the motor entry point.
*Kelley Electric Machine Company out of Buffalo mostly made woodworking machines, polishers and routers. It is not likely the motor was provided by the planer manufacturer, and was probably added on somewhere early in the machine's history by a previous owner. Possibly even by the US Govt since it has war tags & the work is neatly done.
My plan is to bring out new leads and get the planer operational for the time being. Then I want to plan to add a larger motor if necessary, and am trying to figure out what speed to work with. I can probaby machine a plate & the motor shaft, and make a new 5HP motor fit the planetary drive. But I am not yet clear how fast the old motor is turning.
So, if it has 36 poles, and was rated 50Hz but is running on 60Hz, (wired 220 volts, 8 amps) How fast should it be spinning?
Yeah, I know I can get it fired back up and count, but it would be easier to know if poles x Hz = predictible rpm?
Thanks!
