December 8, 2011 - WITTENSTEIN introduced a swing servo, also known as the wing motor because of its appearance.
The hollow-shaft direct drive wing motor has two swinging stator halves that feature a mounting concept for integration and operating scenarios where axial installation and removal in or from a machine are not possible. The split stator contains two parallel, three phase systems which allow for the stator to be joined together in a controlled way. Each stator half contains a water-cooling pipe system made from stainless steel. It prevents damage to the drive due to intense heat stemming from the roll. It can be retrofitted or dismantled at any time for maintenance, and is designed to withstand the harshest of operating environments.
This motor operates the same way as a classic, one-piece direct drive. The wing motor has a very high efficiency and is very low on energy.
