Huco Dynatork’s air motor is based on a free-floating piston design that is capable of precise position control.

Maximum torque is transmitted on start-up and this can be adjusted to fine limits by standard air-flow valves.

Unlike other makes that operate with a system of metal pistons and connecting rods, the Huco Dynatork motor is suitable for stop/start load speed applications under load.

Unlike its vane counterpart, the Huco Dynatork air motor is also easier to seal, and is therefore more cost-efficient as most of the energy stored up in the compressed air is converted into motion.

In fact, it consumes up to 80 per cent less air than a vane motor providing cost savings even at maximum torque.

The clean motor is available with non-lube air supply and in a corrosion resistant or acetyl housing.

Aluminium foil tray manufacturer, Coppice Alupack, has replaced all its electric drives on rewind systems that handle the surplus foil after the aluminium coil has been stamped.

Inclusion of Huco Dynatork air motors has simplified the design and made it more controllable and safer.

Their clean, non-lube running has also ensured hygienic production.

The Huco Dynatork motors run from 0-220rpm for 24h a day in a cycle that goes from stall to start in the order of 60 times per minute.

James Lamin, engineering manager at Coppice Alupack, said: ‘The piston air motor has allowed us to adjust most of the tension out of the system to eliminate lacing breakage.

‘It has also made the process inherently safer by reducing torque and negating the need for any electrical cables.’ A further benefit is that maintenance of the motors can now be carried out by a shop-floor technician instead of a skilled electrician, saving cost and minimising downtime.

The suitability of the Huco Dynatork motor for stop/start applications under load has also been proven by Greydon, a manufacturer of printing equipment for form, fill and seal packaging machinery.

Its Bagaire taped bag loader ensures bags are presented quickly and in exactly the same position to the operator, time after time.

This accuracy makes the system ideal for the inclusion of inkjet coding.

The operating principle is simple but effective.

A leader tape is wound around two drive pulleys.

When powered up, the system advances the bags by winding up the tape and pulling them up from underneath the load table.

The Huco Dynatork air motor is responsible for this operation and again provides a clean solution that is also suitable for washdown.

Huco Dynatork is a world-class manufacturer of flexible couplings.

Whether the need is for high torsional stiffness, generous misalignment capability, high-speed operation or a capacity for operating in push/pull mode, Huco Dynatork can help. And if your requirements fall outside our standard range, we offer a customised service and cost-efficient small-batch production. 

Our range is highly comprehensive, comprising membrane and bellows high-performance couplings; Oldham and Uni-Lat general-purpose motion control couplings; Single-Beam, Multi-Beam and Step-Beam brands; and jaw/spider and double loop light power drive couplings. We also stock stainless steel and plastic universal joints.

Although the design and manufacture of couplings remains the cornerstone of our business, this is just one of the company's five main product groups. Huco Dynatork piston air motors is one of them, the only brand that can be used for precision motion control. 

Our quality hallmark is also impressed onto a huge range of power transmission and motion control components that have distinct design and performance benefits over other products in the market. In addition to an extensive choice of stock gears, racks, ground shafts and spline shafts, the product programme also includes the comprehensive BSA range of leadscrews and ballscrews.
