The Marine Eaton Dowmax ME Series Motor is a remarkable low-speed, high-torque motor featuring a double swash plate axial piston design that excels in the low-speed range. Here are some key features of this motor:

• Wide Range of Models: Available in 13 displacements ranging from 99 to 4097 cm3/rev.
• High Pressure: Capable of continuous operating pressures of 27.5 MPa (280 kgf/cm2) and 24.5 MPa (250 kgf/cm2).
• Smooth Operation: Multiple pistons and a double swash plate ensure smooth rotation even at speeds as low as 1 rev/min.
• High Starting Torque and Efficiency: Offers high starting torque and overall efficiency.
• Compact and Easy Installation: Designed for easy and space-efficient installation.
• Robust Construction: Built to withstand demanding marine environments.
• Quiet Operation: Operates quietly for enhanced comfort.
• Thermal Shock Resistant: Unaffected by thermal shock, making it ideal for cold temperature starts.
• Speed Pickup System: Optional speed pickup system available for enhanced functionality.

Marine Eaton ME Series Motor Structure

The structure of the Marine Eaton ME Series Motor involves a precise fluid flow mechanism. Here’s how it works:

Fluid enters through the supply port and is channeled through internal passages and a timing plate to reach the center of the cylinder bores. When fluid pressure builds up, it pushes the pistons apart, causing the slippers to slide along the angled surfaces of the swash plates. This action leads to the rotation of the barrel and shaft assembly, generating the necessary mechanical output.

Once the motor has completed its work, the fluid is then exhausted through the timing plate and internal passages, ultimately exiting through the return port. This well-designed flow system ensures efficient operation and performance of the Eaton ME Series Motor in marine applications.

Eaton ME Hydraulic Motor Selection Chart

The Eaton ME Hydraulic Motor Selection Chart illustrates the relationship between actual torque and shaft rotation under rated pressures of 27.5 MPa (280 kgf/cm2) and 24.5 MPa (250 kgf/cm2). By using this chart, one can choose the appropriate model based on the required torque and shaft speed. If the operating pressure deviates from 27.5 or 24.5 MPa (280 or 250 kgf/cm2), the performance data for the relevant model should be consulted for accurate guidance.

Marine Eaton Dowmac MK Series Two-Speed Hydraulic Motor

MK Series Hydraulic Motor Model Types We Supply: MK300, MK600

The Marine Eaton Dowmac MK Series Two-Speed Hydraulic Motor features a straightforward structure that leverages the independent travel of front and rear pistons, combining the benefits of opposed pistons and double swash plates. Here are some key points about this motor:

• High Starting Efficiency: Offers excellent starting efficiency due to a working structure similar to the standard DOWMAX motor.
• Good Low-Speed Performance: Achieves good low-speed performance thanks to its multiple-piston construction.
• Slim Configuration: Maintains a slim profile with a motor diameter equivalent to the standard DOWMAX motor.
• On-the-Fly Displacement Change: Allows for seamless transitioning between large and small displacements even while under load.
• No Separate Pilot Pressure Required: Change-over operations do not necessitate a separate pilot pressure as the self-pressure is utilized for this purpose.

Marine Sumitomo Eaton MB Series Hydraulic Motor

MB Series Hydraulic Motor Model Types We Supply

The Marine Sumitomo Eaton MB Series Hydraulic Motor features a wet multi-disc brake of the pressure-release type, known as a negative brake type. Here are some key characteristics of this hydraulic motor and its mechanical brake system:

• Pressure-Release Brake: The brake remains engaged at all times and is only released when pilot fluid is directed through the brake releasing port. No adjustments are required post-installation.
• Mechanical Brake Options:
  • Cartridge type mechanical brake (BB, BC, BP, BR types): Allows for easy mounting and dismounting with the hydraulic motor.
  • Integral shaft type mechanical brake (MB type): Compact and lightweight design.
• Durability: The mechanical brake features wet-type multiple discs/plates, ensuring high durability.
• Versatility: With a large torque capacity, it is suitable for a wide range of applications.
• Safety: Operation safety is guaranteed by the pressure-release mechanism, releasing the brake only when pressure is applied.
• Compact Design: Easy to install on various equipment due to its compact construction.
• Radial Load Capability: Offers a large radial load capacity, thanks to the adoption of a large capacity roller bearing on the drive shaft.
• Service Access: The brake motor allows for quick servicing, as either the brake or motor can be easily removed.
