Empire Magnetics Inc.: Hollow Shafted Motors - Frame Size 23 (VS Series)

Laboratory Grade Vacuum Products - add model prefix VX

The vacuum rating for this motors is 10-7 Torr. The internal temperature rating is 180oC internal and 155o for the case. The bearing lubricant vapor pressure is below 10-9 Torr at 100oC. This motor is cleaned and baked, and undergoes a proprietary extraction process to remove contaminants. It should be handled under clean room conditions with nylon gloves.
VX grade is our premium product offering. It is typically used when even very small amounts of contamination are of concern to the customer. Some applications have been: space based optical systems, semiconductor manufacturing chambers and electron beam equipment.

Standard Grade Vacuum Products - add model prefix VS

These products have a vacuum rating of 10-7 Torr and temperature rating of 155oC internal and 130o for the case. The bearing lubricant vapor pressure is below 10-8 Torr at 100oC. This motor is subjected to an industrial cleaning process, vacuum baked to encourage outgassing of residual contaminants and is sealed qin a nylon bag.
VS grade is our "standard" product offering. It is typically used when very clean is good enough. Often the VS grade is selected for vacuum chamber applications where the chamber will be opened frequently, the contamination from the outside air will normally exceed that of the VS grade equipment, so it is deemed suitable for the application.
NOTE: The Standard Grade has recently tested to exceed Class 10 clean room requirements.

Commercial Grade Vacuum Products - add model prefix VC

The Commercial Grade had a vacuum rating of 10-6 Torr. These motors are temperature rated at 130o C internal, and 105o for the case. The bearing lubricant vapor pressure is below 10-6 Torr at 100o C. This motor will give off a small quantity of vaporization products and no special handling is required.

Typical applications:

VX - Laboratory

  • Space based optical systems

  • Semiconductor manufacturing chambers

  • Electron beam equipment

VS - Standard

  • Experimental chambers subject to frequent openings

  • Sputtering and diffusion equipment

  • Clean room equipment

VC - Commercial

  • Vacuum forming

  • Vacuum casting

  • Vacuum welding

Hollow Shafted Motors - Standard Grade - VS Frame Size 23

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.


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.
