IAC series - Dual displacement hydraulic motors
The IAC series motors are dual displacement radial piston hydraulic motors designed for low speed and high torque applications. They feature a rotating shaft and stationary housing, with pistons that provide mechanical force against an eccentric cam to generate torque. The motors are equipped with a distributor for oil flow regulation and an external valve for displacement control, allowing for two different displacements within the same motor.
The IAC series is versatile, suitable for marine equipment, winches, offshore equipment, conveyors, steel bending machines, forklifts, skid steer loaders, dumpers, agricultural and forestry machines, municipal vehicles, and airport machinery.
Key features include high volumetric and mechanical efficiencies, smooth operation at low speeds, high starting and constant torque, a wide speed range, compact design, low maintenance, high reliability, bi-directional operation, dual speed capability, high radial and axial force tolerance, freewheeling, and available built-in valves and speed sensors.
The catalogue provides detailed technical data for various models, including displacement, specific torque, speed ranges, mechanical and starting efficiencies, continuous and peak pressures, flushing flow, and dry weight. For example, the IAC 195 H1 model offers a displacement range from 195 to 69 cc, with a continuous speed of up to 1100 rpm and a peak pressure of 350 bar.
Recommendations for hydraulic fluid and maintenance procedures are provided to ensure optimal performance and longevity of the motors. This includes guidelines for flushing, shaft seal features, and conversion formulas.
The document includes an ordering code system for specifying motor configurations and an interchangeability chart for compatibility with other brands like Staffa, Kawasaki, Parker, Denison-Calzoni, and Kayaba.
A troubleshooting section is available to address common issues, and contact information is provided for further assistance from Italgroup.
The document provides technical specifications for Italgroup's IAC series hydraulic motors. Key specifications include hydrostatic pressure test: 420 bar, temperature range: -30 to 70 °C, mechanical efficiency varies by model, with examples showing efficiencies from 73.4% to 87.5%, and continuous power output ranges from 15 kW to 78 kW depending on the model and flushing conditions.
To estimate input power, divide the output power by the mechanical efficiency. For example, if the required output power is 60 kW and the starting efficiency is 82.5%, the estimated required power is 72.7 kW.
Performance diagrams are provided for different models, indicating continuous, intermittent, and peak operation conditions. Operational limits are based on fluid viscosity and temperature, with a maximum working temperature of 70 °C.
Detailed installation drawings are included for various configurations, specifying port sizes, shaft types, and displacement changes.
For optimal performance, ensure the hydraulic fluid is within the recommended viscosity range. Flushing is advised if the working temperature increases beyond ideal conditions.
The data in the catalogue is for product description purposes only and should not be interpreted as legally binding characteristics. Italgroup reserves the right to make modifications without notice.
The document provides performance diagrams for the IAC 1400 H5 and IAC 2200 H55 hydraulic motors, detailing continuous, intermittent, and peak operation conditions. Continuous operation is standard, while intermittent operation is allowed for 15% of the duty cycle, up to 3 minutes. Peak operation is permissible for 3-5 seconds every 10-15 minutes. The diagrams assume ideal fluid conditions with a viscosity of 40 cSt. If the working temperature exceeds 70°C, adjustments in flushing or oil grade are necessary.
The IAC 2200 H55 motor specifications include various displacements ranging from 2200 cc to 82 cc, with corresponding specific torque, speed, mechanical efficiency, and power outputs. Continuous pressure is maintained at 270 bar, with intermittent and peak pressures at 310 and 350 bar, respectively. The document also outlines the flushing flow requirements and dry weight for each displacement.
Bearing life is influenced by radial load and shaft speed, with examples provided for different conditions. Volumetric efficiency and external leakage are detailed for various pressures and speeds, with examples illustrating efficiency calculations.
Installation drawings for the IAC 2200 H55 and IAC 3000 H6 series are included, showing shaft types, port configurations, and displacement change options. The document specifies CETOP 3 fitting configurations and ordering codes for customization.
