48 frame motor dimensions.

Certain nema 56z frame motors have 1 2 x 1 1 2 long shaft with 3 64 flat. Electrical motors full load amps full load currents for 460 volts 230 volts and 115 volts motors single and 3 phase. For example if you have a 324t frame motor every manufacture of motor will have the same shaft diameter shaft length and bolt hole mounting dimensions but be warned your physical size of the motor may differ. Typical examples of frame numbers 48 56 145 and 215.

In this case each frame size designates a particular shaft height shaft diameter and face or base mounting hole. Similarly a 56 frame motor would have a shaft height of 3 1 2 inches.
