A provider of MRO services to the aviation industry based in southern Europe has taken delivery of a Barbour Stockwell spin test facility for the testing of electrical rotors for auxiliary power units on aircraft. This particular apparatus is the latest in a series of identical machines supplied to numerous customers worldwide who are performing similar testing activities.

The skid-based, electric motor-driven instrument is capable of speeds up to 40,000 rpm under the precise control of a direct torque control-based drive system. The vacuum chamber has a diameter of some 450 mm and is fitted with a containment ring and lid locks to ensure absolute safety in case of a test article bursting.

After extensive factory acceptance tests at Barbour Stockwell in Boston, Massachusetts, the machine was shipped to the customer in Europe, where it was installed within weeks. The customer’s staff also received ample product training.
