This page provides dimensioned 2D assembly drawings of DRG Motor electric motors in PDF format. The drawings cover IEC frame sizes from 80 up to 355 in foot-mounted (B3), flange-mounted (B5), foot-and-flange (B35) and face-mounted (B14) versions. A 2D drawing is the quickest way to check dimensions on paper before a motor is fitted to your machine.

What a 2D drawing is used for

  • Installation dimensions: overall length, height and width, plus the clear space the motor needs.
  • Shaft diameter and length: shaft and key dimensions for choosing the right coupling, pulley or gearbox connection.
  • Flange dimensions: for B5 and B14 versions, the outer flange diameter, spigot diameter and bolt pitch circle.
  • Foot hole spacing: for B3 and B35 motors, check hole centres and hole diameters before drilling a base frame.
  • IEC frame size: the shaft centre height is the key reference when replacing an existing motor with one of the same frame.

How to pick the right drawing

Identify the frame size of your motor (for example 132, 160 or 280) and its mounting arrangement, then open the PDF for that frame and mounting type. Frames 315 and 355 have separate drawings by shaft diameter. If you need to place the motor inside your own CAD design, 3D STEP models are offered on a separate page.
