Borelli 14 daNm Electromagnetic Clutch – 30929-1/7 / 30930-1/7 Series

Description

The Borelli 14 daNm Electromagnetic Clutch – 30929-1/7 / 30930-1/7 Series is a premium technical solution specifically designed for precise and reliable power transmission control in complex hydraulic and industrial systems. This component ensures maximum efficiency and precision, operating in reversible configurations suitable for a wide range of system requirements and advanced mechanical layouts.

Technical Specifications and Performance

The system is engineered with strict tolerances to withstand highly demanding workloads. It delivers a static torque of 14.0 daNm, while its rated nominal torque is 11.8 daNm. Dynamic torque follows a decreasing curve as operating speed increases: 12.5 daNm at 500 rpm, 11.0 daNm at 1000 rpm, 8.2 daNm at 1500 rpm, 7.5 daNm at 2000 rpm, 6.7 daNm at 2500 rpm, and finally 6.5 daNm at 3000 rpm. The maximum operating speed permitted by the mechanical tolerances is 5000 rpm, ensuring considerable versatility for high-speed coupling applications. The complete clutch assembly weighs just 5.5 kg, an important factor for structural balance.

Operating Dynamics and Response Times

Dynamic operating efficiency is ensured by extremely fast magnetic and electromagnetic response times. Specifically, the clutch requires an engagement time of just 25 ms, while disengagement takes 40 ms. To preserve the component’s thermal and mechanical integrity during operating cycles, a minimum waiting interval of 20 seconds between consecutive engagements must be strictly observed. The main mechanical interface of this assembly features a reliable DIN 5482 spline profile measuring 35×31, combined with a specially designed 7-groove PLV pulley.

Electrical Consumption and Power Supply

Electrical power is supplied to the excitation coil through a dedicated 2×2.5 electrical cable. Electrical consumption and power specifications differ significantly between the two voltage versions available in the catalogue:

• 30929-1/7 Series (12 V DC): At 20°C, it has a measured resistance of 5.60 Ohm, draws 3.33 A, and has a corresponding power consumption of 40.00 W. At 120°C, resistance decreases to 4.00 Ohm, with current consumption of 2.00 A and power consumption of 24.00 W.
• 30930-1/7 Series (24 V DC): At 20°C, it has an internal resistance of 28.00 Ohm, requiring a nominal current of 1.26 A for a total power consumption of 30.30 W. When the temperature reaches 120°C, resistance decreases to 20.00 Ohm, with current consumption of 0.77 A and power consumption of 18.18 W.

Thermal performance data clearly indicate that at an operating temperature of 120°C, nominal performance decreases by 20% in all cases.

Construction Features and Components

The exceptional durability of the entire assembly is ensured by the use of high-precision mechanical components. The robust internal structure includes two reliable SKF 6009 2RS radial bearings, multiple oil seals (35x50x7 and 45x60x7), and a drive shaft specifically designed to withstand the system’s considerable dynamic loads. The moving components are securely held in place by robust d.45 retaining rings and suitable keys compliant with the UNI 6606 4×6.5 standard. The housing is fastened using standardized EN 24017 screws (M6x12, M8x35) and UNI 5931 socket head cap screws (M6x20).

Available Configurations and Flange Options

To ensure precise mechanical and functional compatibility with the wide variety of hydraulic pumps available on the market, the entire series offers an extensive range of dedicated flanges, covering SAE A and SAE B standards as well as specific connections for Group 2 Bosch, Group 3, and Group 3 Bosch pumps. This high degree of modularity enables seamless integration into most stationary and mobile hydraulic power units and transmission systems, minimizing dimensional compatibility issues.
