Topic tags/keywords: delta 17-900 motor frame size drill press

I am looking to purchase a 3-phase motor and add a VFD for speed control. I cannot locate the frame size of the existing motor.

If anyone has done this with their drill press I would appreciate your advice.

Thank you,

The motor data plate doesn’t list it, but it’s probably a standard 56 frame. If you have the existing one, just measure and look it up:

NEMA electrical motor frame sizes (at Engineering Toolbox)

Too bad you are so far away… I have a 3/4hp 3 phase Dayton just sitting on the shelf gathering dust :(


PS: You might also want to consider a variable speed DC motor. You can get the motor, controller and power supply for free out of an old treadmill. They are typically around 1.5 to 2.5 HP.
