Empire Magnetics Inc.: Dustproof Stepper Motors (Frame Size 23/34/42)

Dustproof Motors

Many industrial operations involve the use, production or processing of materials in powder form. Motors used in the automation of such processes are prone to failures when particulates migrate into unprotected bearings and motor cavities.

Empire Magnetics dustproof motors survive in environments where other motors fail.

Features include built-in O ring seals that eliminate dust leaks at potential penetration points, motor insulation that allows operating at 145 degrees C, case temperature (185 degrees C winding temperature) and air fittings for pressurization are supplied; pressure rated to 15 psi to lock out contamination.

Empire Magnetics dustproof motors are available in industry standard size 23, 34, 42, and 65 frame sizes. Note where seal housing affect usable shaft length.

For the most unique and demanding applications, dustproof and abrasive dustproof step motors can be combined with the following environmental options: radiation hardened, waterproof and extended temperature.

Dustproof Stepper Motors Frame Sizes

Frame size selection:

Motors are typically made in groups or families, the families are identified by the outer diameter or size of the square, these references are called frame sizes. In the American system, a 23 frame is a nominal 2.3 inches in diameter. For motors less than one inch in diameter, the reference is typically known as a size. Herein is a list of the frame sizes offered by Empire Magnetics Inc. and some of the characteristics of the group that will allow you to select from them.

Modifications:

Frame Size 23: Nominal outer dimension of 2.3 inches. Extremely popular size useful for a wide range of industrial applications. Torque range of 60 to 150 oz-in. Cylindrical shaped motor with square front flange.

Model #: DP-U21, DP-U22, DP-U23

Frame Size 34: Nominal outer dimension of 3.4 inches. Power range of 80- 240 watts, useful for a wide range of applications. Torque range of 150 to 450 oz-in. Cylindrical shaped motor with square front flange.

Model #: DP-U31, DP-U32, DP-U33

Frame Size 42: Nominal outer dimension of 4.2 inches. Power range of 240-700 watts, relatively high power in the stepper motor range. Torque range of 400 to 1600 oz-in. Cylindrical shaped motor with square front flange.

Model #: DP-U41, DP-U42, DP-U43
