View Full Version : Best Practice IEC B14 face mount

04-24-2012, 11:09 AM
I am about to machine a mounting for an IEC B14 face mount motor, frame size 63. I assume that the circular recess that I machine should be deep enough to ensure that the motor pulls up only on the flange face with the securing holes in it, not the smaller central boss. I assume that the central boss is simply to provide an accurate radial register.

Is this correct?
