Hello,

A simple question:
What is mounted on a electric motor, D-flanges (N-flanges) or front shield (end shield) or just shields?

I'm a confused finnish engineer trying to translate...

Hello Motortester,

An electric motor is made with different basic thinks, Stator, Rotor, Shaft, Shields, Bearings, Fan, cover fan.

The shield are a motor´s part, but you most make difference between the two motor´s shields,one is the Drive end(DE): in this side you find the shaft and the other is the non drive end (NDE): normally in this side you find the fan.
The flanges are special Drive end shields, with different shapes and are designed to mounting propouse (pump coupling, gear boxes).

Regards

Petronila

I personally tend call them drive end and non drive end endplates, altough I have heard them termed end-shields end-covers and end-bells. A D-flange is essentially a drive-end endplate incorporating a flange for fixing the driven equipment to or mounting the motor. D-flanges generally have 4 untapped holes as standard. A C-face is much smaller than a D-flange for the given frame size and uses 4 tapped holes to hold the driven equipment or mount the motor. Flange and face dimensions are covered by IEC standards in the same way frame sizes are and will be quoted in makers dimension drawings. The standards also use a designation to indicate the chosen generic mounting method that begins with a B.

B3=Foot mtd
B5=Flange mtd
B14=face mounted
B3/5 and B3/14 indicate foot mounting in addition to the flange/face.

There are several Motor mounting combinations. Please see figures for reference.
