Vacuum Rated Stepper Motors for Vacuum Chamber Applications
When you are searching for vacuum-rated stepper motors, consider the overall industrial or aerospace vacuum environment where you will be using the vacuum motors. Whether for use inside a vacuum chamber or in the vacuum environment of space, you’ll want to consider heat generation and outgassing contamination. Vacuum compatible motors manage heat through the use of special motor design and specific winding techniques developed specifically for vacuum applications. As a vacuum motor supplier, we’ve spent years researching and developing the right product for your needs.
Various contaminants that are trapped inside paints, coatings, and greases, can get released into the environment when air is removed from the environment. Our vacuum compatible stepper motors are design using low-outgassing materials to eliminate this concern, and assembled in a cleanroom environment using our proprietary assembly process. As a solution to vacuum motor applications, this approach also eliminates the majority of concern about contaminants entering the system.
We use proprietary motor assembly process to manufacture their industrial vacuum motors and aerospace vacuum motors, and we’ve compared our results with major competitive devices in a positive flow chamber that measured outgassing levels. Our vacuum compatible motors repeatedly outperformed the competition, making them the cleanest motors on the market today. Contact us for specific information.
The following motors are available as vacuum rated:
Specifically designed to be used in satellites and space craft, applications for our vacuum rated motors range from communication antennas to vehicle controls. We are an AS9100C registered manufacturer, and each motor is manufactured to meet the strict aerospace guidelines.
Proprietary Motor Assembly Process
In order to create the cleanest motor on the market, we’ve created our own motor assembly process and put the results to the test—against a known competitor’s motor. To do so, we placed our motor into a positive flow chamber (N2 Gas flow 1mm/1min) and measured its outgassing levels over a 72 hour period at a temperature of 125°C. Then we took the following measurements:
- Total Mass Loss Percentage (%TML)—The larger the percentage, the more contaminated the specimen.
- Total Mass Loss (ug/motor)—This is the weight of the mass that was evaporated into the chamber from the specimen. The larger the number, the more contaminated the specimen.
|Sample||% Total Mass Loss (TML)||Mass Loss (ug/motor)|
The Lin Engineering vacuum rated motor lost far less mass than the competitor’s motor, proving the cleanliness of the system. Our cleaning process in 375% cleaner than the competition.
