Vacuum Capacitor Stepper Motor

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.
