CE-Series

The combination of compact size, low weight and low efficiency makes the CE motor the best wheel drive motor available. To reduce the overall length and weight of the motor, all unnecessary material has been removed from the housing and the valve has been fitted to the front of the rotor. The pressure compensated balancer plate allows the motor to maintain a high volumetric efficiency at start-up and a high mechanical efficiency during operation. All of these features make CE Series motors 10-25% lighter and more compact than the competition, making them perfect for applications with strict weight and size requirements.

• Displacement: 120-750 cm³/rev
• Max. System pressure (peak): 241 bar
• Max. Speed (continuous): 360 rpm

Features and benefits:

• The needle bearing is optimally positioned to allow the load to be placed as close as possible to the centerline of the bearing
• Three bearing options allow the load carrying capacity of the motor to be matched to the application
• The valve in the motor provides cost-effective and efficient oil distribution and reduces the overall length of the motor
• Pressure compensated balancer plate improves volumetric efficiency at low flow and high pressure

RE-Series

RE-Series motors offer the perfect compromise between price and performance, providing high work output at a reasonable price. Although these motors perform well in a wide range of applications, they are particularly suitable for low flow, high pressure applications. During start-up, the pressure causes the balancer plate to flex towards the rotor, which significantly improves volumetric efficiency. When the motor reaches operating pressure, the balancer plate relaxes, allowing the rotor to rotate freely, resulting in higher mechanical efficiencies. This power is transmitted to the output shaft via the most durable drive link in its class. Four bearing options in combination with standard mounting flanges and output shafts allow the motor to be configured for almost any application.

• Displacement: 120-750 cm³/rev
• Max. System pressure (peak): 276 bar
• Max. Speed (continuous): 360 rpm
• Max. Flow rate (continued): 83 l/min
• Max. Torque (cont.): 1,096 Nm
• Temperature range: -30°C - 85°C
• Optimum viscosity: 20 - 43 cSt
• Filtration: min. ISO 17-14
• Values vary depending on the type and size of the motor

Features and benefits:

• High pressure shaft seal provides superior seal life and performance and eliminates the need for case draining
• Three bearing options allow motor load capacity to be matched to application
• Heavy duty drive member is the most durable in its class and receives full flow lubrication for long life
• Valve in motor provides cost-effective and efficient oil distribution and reduces overall motor length
• Pressure compensated balancer plate improves volumetric efficiency at low flow and high pressure
