Motor gives machinery wiiiiiiings

This direct-drive design is for all of you plant engineers reading Motion System Design. The swing servo, also known as the wing motor because of its appearance, is the newest innovation in motor mounting.

The hollow-shaft direct drive wing motor has two swinging stator halves that offer an alternative way of mounting for easier integration in designs where axial installation and removal from a machine are not possible.

Engineers at Wittenstein Inc., Bartlett, Ill., created this wing motor as a customized direct drive for rollers, to allow the machine builders to fully integrate the motor into existing layouts without extending the roll periphery.

The split stator contains two parallel three-phase systems that 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, to prevent damage to the drive due to intense heat stemming from the roll.


Key features: It can be retrofitted or dismantled at any time for maintenance, and is designed to withstand harsh operating environments.

What else: This motor operates the same way as a classic, one-piece direct drive with impressive performance. The wing motor has very high efficiency and is very low on energy consumption.
