Available in 12 V DC and 24 V DC versions, it features mounting options for various Group 2 and Group 3 flanges. The available product codes are: 30917, 30909, 30925, 30901/SA, 30901/SB, 30919, 30911, 30927, 30903/SA, 30903/SB.
Borelli 10 daNm Electromagnetic Clutch – 30901 / 30903 Series
The Borelli 10 daNm Electromagnetic Clutch – 30901 / 30903 Series is a premium solution for controlling power transmission in hydraulic systems. All electromagnetic clutches in this series are fully reversible, ensuring exceptional operational flexibility in industrial installations. The system is designed to operate with a minimum interval of 20 seconds between consecutive engagements, ensuring stable operating cycles and preventing abnormal overheating. The total unit weight is 5.5 kg. The electromagnetic clutch is powered through a dedicated 2×2.5 electrical cable.
The mechanical performance of the device has been rigorously tested to meet the most demanding operating requirements. The clutch delivers a nominal torque of 7.8 daNm and a maximum static torque of 12.5 daNm. Dynamic torque varies according to motor rotational speed: at 500 rpm, it reaches 8.5 daNm, decreasing to 7.0 daNm at 1000 rpm and further to 2.5 daNm at 3000 rpm. The component supports a maximum operating speed of 5000 rpm. The mechanism offers extremely fast response times, with an engagement time of 25 ms and a disengagement time of 40 ms.
The Borelli 10 daNm Electromagnetic Clutch – 30901 / 30903 Series is available in two voltage configurations. The 30901 Series operates at 12 V DC, drawing 3.33 A at 20°C with a power consumption of 40.00 W. At 120°C, current consumption decreases to 2.00 A, corresponding to 24.00 W. The 30903 Series, operating at 24 V DC, draws 1.26 A (30.30 W) at 20°C, decreasing to 0.77 A (18.18 W) at 120°C. All optimal technical specifications are calculated at 20°C; when operating at temperatures of 120°C, performance decreases by 20%.
Structural durability is ensured through the use of high-quality components. The internal assembly incorporates two SKF 6009 2RS sealed ball bearings and a sealing system consisting of 35x50x7 and 45x60x7 seals. The transmission shaft features a standardized DIN 5482 35×31 spline profile, ensuring efficient torque transmission without losses. The external assembly is enclosed in a robust metal housing, sealed with a dedicated gasket to prevent fluid contamination. The system offers extensive installation versatility thanks to multiple flange configurations for hydraulic pumps, including Gr. 2 BOSCH (code 30817), Gr. 3 (code 30803), Gr. 3 BOSCH (code 30821), as well as SAE A (code 30420.3) and SAE B (code 30420.1) flanges. These design options enable direct, secure and precise coupling with a wide range of industrial machinery used in hydraulic applications.
