Borelli 14 daNm Electromagnetic Clutch – 30929 / 30930 Series
The Borelli 14 daNm Electromagnetic Clutch – 30929 / 30930 Series is a high-performance, reversible component designed for hydraulic circuits. It delivers a static torque of 14.0 daNm and a maximum speed of 5000 rpm. Available in 12 V DC and 24 V DC versions, it ensures fast engagement times of just 25 ms. Featuring a standard DIN 5482 35×31 spline profile, it is compatible with the main flange configurations available on the market. The available product codes are: 30929/2B, 30930/2B, 30931, 30932, 30931/3B, 30932/3B, 30929/SA, 30930/SA, 30929/SB, 30930/SB.
Borelli 14 daNm Electromagnetic Clutch – 30929 / 30930 Series
The Borelli 14 daNm Electromagnetic Clutch – 30929 / 30930 Series is an advanced technical solution for controlling power transmission in industrial hydraulic systems. All models in this series are fully reversible. Mechanical coupling is ensured by a spline profile compliant with the DIN 5482 35×31 standard. The assembly features a robust housing (code 30009.1), which accommodates a dedicated transmission shaft (code A30901). Smooth rotation and reduced friction are ensured by two high-performance SKF 6009 2RS bearings (code 506009/2Z). Fluid sealing is provided by dedicated oil seals (35x50x7 and 45x60x7), together with specific gaskets designed to prevent contamination. The internal components are secured by 45 mm retaining rings (Seeger) and a UNI 6606 4×6.5 key, while the electrical wiring is safely connected through a 2×2.5 cable.
The device delivers outstanding mechanical performance, with a nominal torque of 11.8 daNm and a maximum static torque of 14.0 daNm. Under dynamic operating conditions, torque progressively varies according to rotational speed: at 500 rpm, dynamic torque reaches 12.5 daNm, decreasing to 11.0 daNm at 1000 rpm and 8.2 daNm at 1500 rpm. At higher rotational speeds, measured values are 7.5 daNm at 2000 rpm, 6.7 daNm at 2500 rpm, and finally 6.5 daNm at 3000 rpm. The electromagnetic clutch is engineered to withstand a maximum rotational speed of 5000 rpm. Electromagnetic response times are calibrated to ensure exceptional efficiency: engagement takes just 25 milliseconds, while disengagement occurs in 40 milliseconds. For operational safety, a minimum interval of 20 seconds between consecutive engagement cycles must be strictly observed. The complete assembly has a total weight of 5.5 kg.
The Borelli electromagnetic clutch incorporates a high-efficiency coil assembly (codes 401214/153 and 402414/153). The 30929 Series operates at 12 V DC, while the 30930 Series is specifically designed for a 24 V DC power supply. Temperature variations affect electrical consumption. At an operating temperature of 20°C, the 12 V version has an electrical resistance of 4.00 Ohm, draws 3.33 A, and has a rated power consumption of 40.00 W. Under the same conditions (20°C), the 24 V version has a resistance of 20.00 Ohm, draws 1.26 A, and consumes 30.30 W. When the component reaches more demanding operating temperatures of up to 120°C, the resistance of the 12 V model increases to 5.60 Ohm, reducing current consumption to 2.00 A (24.00 W), while the 24 V model reaches 28.00 Ohm, drawing 0.77 A (18.18 W). Overall performance decreases by 20% when the operating temperature reaches 120°C.
To ensure maximum flexibility when installing the clutch in existing hydraulic circuits, the unit supports multiple connection interfaces. Available flange configurations include versions for Group 2 BOSCH, standard Group 3, and Group 3 BOSCH pumps. The unit is also compatible with major American industrial standards, offering direct connections for SAE A and SAE B flanges.
