ME series motors with gearbox
Our ME series motors with gearbox feature double swash plates and multiple opposed pistons. These low-speed high-torque (LSHT) hydraulic motors are available with displacements ranging from 99 cm3 to 4,097 cm3 [6 in3 to 250 in3] and are equipped with various gear box ratios to enable low speed with smooth operation and very little torque ripple. They can operate on a wide range of fluids, including water-glycol, and are well suited for applications such as directional drilling machinery, top-head drives, and marine winches.
Features and benefits
- Developed with planetary gear suitable for shield tunneling
- All DOWMAX motors and planetary gear reduction motors are mutually compatible
- Multiple pistons and double swash plate result in smooth rotation at speeds down to 1 rpm
- High starting torque and overall efficiency
- Robust construction but quiet operation and compact construction for easy installation
- Unaffected by thermal shock (good for starting at cold temperature)
- Wide range of uses in different mediums such as water glycol and phosphate-ester
Applications
- Construction: cranes, tunnel-boring machines, special and regular rotary drill rigs, rain maintenance cars, grapples, excavators, and earth augers
- Processing: conveyors/rolling drives, steel mills, and injection molding machines
- Oil, gas, and marine: winches, ship steering systems, cranes, capstans, and thrusters
- Entertainment: ferris wheels and amusement park machines
