UHV Compatible Stepper Motors

Ultra High Vacuum Stepper Motors

From £600.00 excl. VAT and transportation cost

AML UHV compatible stepper motors are available in a range of sizes with torque ratings from 70 mNm to 800 mNm. They are suitable for low speed precision in-vacuum manipulation without the use of particle generating motion feed-throughs. The considerable reduction in mechanical complexity, absence of metal to metal sliding surfaces and low outgassing characteristics make these motors especially suitable for sensitive handling applications.

All motors are designed, cleaned, hand assembled and conditioned to UHV standards in our ISO Class 7 cleanroom.
