Empire Magnetics provides quality motor products designed to perform in environments and applications where ordinary motors are unsuitable.
- VX - Laboratory Grade Vacuum Products
The vacuum rating for this motors is 10-7 Torr. The internal temperature rating is 180o C internal and 155o for the case. The bearing lubricant vapor pressure is below 10-9 Torr at 100o C. 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. - VS - Standard Grade Vacuum Products
These products have a vacuum rating of 10-7 Torr and temperature rating of 155o C internal and 130o for the case. The bearing lubricant vapor pressure is below 10-8 Torr at 100o C. 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. - VC - Commercial Grade Vacuum Products
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.
