Borelli 14 daNm Electromagnetic Clutch – 30980 / 30981 Series

Description

The Borelli 14 daNm Electromagnetic Clutch – 30980 / 30981 Series is an advanced mechanical solution for power transmission in professional hydraulic circuits. Developed to operate precisely under demanding loads, this device ensures excellent operational reliability in industrial applications.

Technical Specifications and Performance

In terms of performance, the clutch delivers a static torque of 14.0 daNm and a nominal torque of 11.8 daNm, ensuring reliable power transmission. Dynamic torque values vary according to rotational speed: at 500 rpm, torque reaches 12.5 daNm; at 1000 rpm, it is 11.0 daNm, decreasing to 8.2 daNm at 1500 rpm. Torque progressively decreases to 6.5 daNm at 3000 rpm. The system supports a maximum rotational speed of 5000 rpm. Response times are extremely short: engagement takes 25 ms and disengagement takes 40 ms, with a minimum interval of 20 seconds required between consecutive operations. The total weight is 5.8 kg. The rated technical specifications refer to an operating temperature of 20°C; at 120°C, performance naturally decreases by 20%.

Construction Features and Components

The internal structure of the clutch incorporates high-quality mechanical components designed to ensure long-lasting sealing performance and durability. Key elements include a robust central shaft, a dedicated protective housing, SKF 6009 2RS radial bearings, and specific oil seals (35x50x7 and 45x60x7). The assembly is completed by the electromagnetic clutch unit and preconfigured flanges for Group 1-2 pumps. Mechanical fastening is achieved using EN 24017 screws (M6x12 and M8x35) and socket head cap screws (T.C.E.I.), with dedicated sealing gaskets. It is important to note that all electromagnetic clutches in this series are fully reversible.

Electrical Consumption and Power Supply

To accommodate different system requirements, the product family is available in two operating voltages: the 30980 Series operates at 12 V DC, while the 30981 Series is designed for 24 V DC. At the reference temperature of 20°C, the 12 V version has a resistance of 4.00 Ohm, drawing 3.33 A with a total power consumption of 40.00 W. At 120°C, power consumption decreases to 24.00 W. The 24 V model, also at 20°C, has a resistance of 20.00 Ohm and draws 1.26 A, corresponding to a power consumption of 30.30 W (decreasing to 18.18 W at 120°C). Electrical connection is provided through a dedicated 2×2.5 cable.

Flanges and Adaptability

Application flexibility is ensured by a wide range of interface flanges. The available models allow direct coupling with standard Gr.2 BOSCH, Gr.3, Gr.3 BOSCH, SAE A and SAE B connections. This versatility enables the component to be installed on various types of hydraulic pumps without requiring costly structural modifications.
