Commercial pricing for vacuum-rated motors
An
Empire Magnetics product story
Edited by the Engineeringtalk editorial team

Commercial-grade VC series vacuum motors are designed to survive pressures as low as 10e-6 Torr.
Commercial-grade VC series vacuum motors are designed to survive pressures as low as 10e-6 Torr.
These motors are temperature-rated at 130C internal, and 105C for the case.
Bearing lubricant vapour pressure is below 10e-6 Torr at 100C.
The VC series are available as stepper, hollow-shaft, brushless servo or rotor nut motors.
They are also available in a variety of frame sizes to provide long life and reliable operation in various commercial grade vacuum applications.
Examples include metal casting, assemblies welding, and forming applications where motion components are incorporated into the moulds.
In these applications, where outgassing and contamination are not critical factors, Empire's lower cost VC grade products are ideal.
Vacuum-rated stepper motors or servo systems can reduce mechanical complexity and increase system uptime in transport systems that are commonly used in applications with vacuum ovens and vacuum deposition systems.
In addition to greater reliability, such systems typically provide greater accuracy and throughput than alternative designs.
