Motor uses less energy to deliver more power

Power management company Eaton has launched the Hydre-MAC, a low-speed, high torque (LSHT) direct drive, radial piston motor – featuring a cam lobe design – for variable speed applications that uses less energy to deliver more power when needed.

With low speed performance, Hydre-MAC is suitable for offshore, marine, metal recovery, mining, pulp and paper and off-highway stationary applications.

The Hydre-MAC motor, created using a MacTaggart Scott heavy-duty motor design, combines MacTaggart Scott’s motor expertise with Eaton’s extensive industry knowledge, particularly in oil and gas, mining and manufacturing applications.

The motor increases component life with two inlet and outlet ports reducing pressure drops at high power; by generating less heat overall; and through a symmetrical 18 piston/roller assembly design, which eliminates piston side-loading and reduces wear and tear.

The Hydre-MAC motor is a direct drop-in replacement for the industry’s most installed motor, reducing switching costs by eliminating the need to replace the machine shaft and torque arm.

Longer component life extends motor life, which not only increases uptime, but reduces the total lifetime cost of ownership. Hydre-MAC’s repairable wear surfaces, including shaft seals, wear rings, piston seals and bearing pads, can be replaced on-site by one of Eaton’s skilled distribution partners.
