Stepping motors and drives have been supplied by Empire Magnetics and Parker Compumotor, respectively. Operating a motor in a vacuum is often perceived as a design challenge because of outgassing, leakage, cooling and corona effects, but, on the other hand, it gives advantages avoiding mechanical feedthroughs which compromise the accuracy and the resolution of the motion and positioning system inside the vacuum chamber. The LIVVS motors are placed inside the probe upper head and are rated to work up to 155°C,well above the maximum head temperature(50°C). The vacuum rating is 10 9mbar. As far as the radiation is concerned, these motors are rated 5108rads (g-radiation total absorbed dose). The bearings dry film lubricant has a vapor pressure of 10 14mbar at 20°C.
