HMF/A/V/R-02. Hydraulic motors for closed and open loop operation
The document details high-pressure axial piston motors suitable for closed and open loop systems. Key features include optimized start-up and low-speed characteristics, optional purge valves, and various shaft and mounting options. Motors are equipped with SAE high-pressure ports and optional speed sensors.
The motors provide smooth low-speed operation, high starting torque, reduced emissions, compact design, high power density, reliability, long service life, and dynamic response characteristics. They also feature a simplified drive line.
Technical data for various motor sizes include displacement, speed, pressure, torque, power, permissible shaft loads, and weights. Identification information such as name plate and serial number is also provided.
Linde Hydraulics' transmission concept allows direct conversion of prime mover speed into wheel speed, reducing drive line components and energy losses. The document compares different motor types and their torque capabilities.
Recommendations for extending service life include maintaining speed and pressure within specified limits, ensuring fluid purity, and using appropriate viscosity fluids. Filtration and pressure fluid guidelines are provided for optimal motor performance.
Details on mounting flange and drive shaft dimensions are provided, along with recommendations for torque transmission components. Specifications for PTO through-drive motors, which allow direct installation into the drive line, are included.
Various motor types such as HMV-02, HMR-02, HMF-02, and HMA-02 are listed with corresponding dimensions and connection details. The document emphasizes modular system features and different configurations.
The document concludes with a note on the current state of development and the possibility of changes due to technical progress. It encourages consultation with sales engineers for product selection and system configuration.
Two types of cooling systems are discussed: a closed loop with options for a cooler in the charge circuit or return line, and an open loop system using the LSC system for energy-saving flow control.
The document outlines components in both open and closed loop circuits, including hydraulic pumps, motors, coolers, filters, and venting valves.
This function is essential for temperature reduction, oil replacement, filtration enhancement, and air removal in both circuit types. Various purge valve settings are detailed.
Explains the force needed for swash plate positioning in variable displacement motors, with options for internal and external supply.
Crossline relief valves protect against pressure overload and prevent cavitation, especially in open loop circuits.
Signal selection for pressure regulators prevents undesirable effects during high-pressure operations, ensuring motors remain at minimum displacement.
These valves prevent motor overspeeding during over-run situations and integrate make-up functions to prevent cavitation.
Various motor types are described, including fixed, variable, and regulating motors with features like stepless control, high starting torque, and compact design. The document also covers motor control options and auxiliary functions.
These configurations offer increased torque and efficiency, with options for direct driveline integration and reduced noise and fuel consumption.
Provides additional high-pressure protection and facilitates the connection of additional motors with minimized hydraulic hose length.
- Operating Pressure: Adjustable regulation begin pressure between 190 to 260 bar, with regulation end pressure 5% above the begin pressure.
- Control Options: Available with pneumatic, hydraulic, and electronic Vmax override controls.
- Protection Class: IP54 (DIN), IP67 (Deutsch), IP 6K6K (AMP).
- Voltage: Rated voltage options of 12V and 24V DC.
- HMR-02: Suitable for both open and closed loop operations, featuring electric signal selection for pressure regulation and optional counterbalance valves.
- HMF-02: High-pressure fixed displacement motor with secondary valves for customized start-up and slowdown, available in sizes 35, 55, 75, and 105.
- HMA-02: Adjustable displacement motor for applications requiring variable displacement, offering flexibility and well-adjusted torque.
- Smooth low-speed operation and high starting torque.
- High power density and reliability.
- Long service life and dynamic response characteristics.
Detailed dimensions for various motor types are provided, including connection threads and pressure connections, adhering to ISO standards.
The motors include options for purge valves, dual setting secondary valves, and integrated LS directional control valves for enhanced functionality in swing and winch drives.
The document lists contact details for Linde Hydraulics' global offices, providing phone numbers and email addresses for customer inquiries.
