The pneumatic motors in the ELSTO programme are developed by Stokvis Group member and winch builder EMCÉ. Not satisfied what was available on the market, a series of contactless gear motors was developed, complete with the relevant control valves. Proven in many winches operating in harsh offshore applications, reliability and performance are outstanding while yielding an excellent price quality factor.
The motors are based on the contactless gear principle in which accurately matching lobes form a continuous expansion chamber in which the compressed air or, when available process gas, is translated form pressure into motor shaft rotation. Thanks to the very accurate gear train synchronising the two motor shafts a reliable operation is guaranteed independent of motor speed or temperature.
