Vacuum Stepper Motors
Available from Empire Magnetics
Ordinary motors cannot operate for long at pressures lower than 10-4 Torr. Empire Magnetics vacuum rated motors are constructed to allow extended operation at pressures as low as 10-7 Torr without a sacrifice in motor performance.
Some vacuum applications cannot tolerate contamination by motor outgassing products. To accommodate a range of motor cleanness requirements, Empire Magnetics provides three grades of vacuum rated stepping motors in the full range of environmental motor sizes.Size 1 medical microstepped motors operate to 25,000 steps per revolution, weigh 0.2 lb, and have a 1.1-in. diameter intended for small spaces. They are specifically designed for mechanical manipulators in neurosurgery, and they can withstand several steam-cleaning cycles in an autoclave for sterilization
