Construction Features and Operating Principle<\/h3>\n

The Borelli 50 daNm Electromagnetic Clutch – 30940\/SF \/ 30941\/SF Series is a precision mechanical solution for power transmission in hydraulic systems. Weighing 20 kg, this electromagnetic clutch features a fully reversible internal design, allowing flexible operation. The assembly is built around a robust housing (code 30009.30) containing a shaft (Ac30940) supported by high-quality bearings (models 3212 A and 16012 A) to ensure excellent reliability. Sealing is provided by 60x75x8 oil seals and dedicated gaskets. The system also includes a 1\/8″G oil drain plug and an M8x1.25 grease fitting.<\/p>\n

Dynamic Performance and Response Times<\/h3>\n

The device delivers outstanding mechanical performance. It provides a static torque of 50.0 daNm and a nominal torque of 38.0 daNm. Dynamic torque varies according to rotational speed: starting at 33.0 daNm at 500 rpm, it decreases to 31.5 daNm at 1000 rpm and reaches 27.0 daNm at 3000 rpm. The clutch supports a maximum operating speed of 5000 rpm. Actuation times are optimized, with engagement taking 25 ms and disengagement occurring in 40 ms. A minimum interval of 20 seconds is required between consecutive engagements.<\/p>\n

Electrical Consumption and Thermal Specifications<\/h3>\n

The series includes two DC power supply variants: the 30940\/SF Series operating at 12 V and the 30941\/SF Series operating at 24 V. For the 12 V model at 20\u00b0C, electrical resistance is 1.81 \u03a9, current consumption is 6.60 A, and power consumption is 80.00 W. At 120\u00b0C, power consumption decreases to 56.00 W. For the 24 V model at 20\u00b0C, resistance is 7.40 \u03a9, current is 3.25 A, and power consumption is 78.00 W (54.60 W at 120\u00b0C). All technical specifications refer to an operating temperature of 20\u00b0C; at 120\u00b0C, performance decreases by 20%.<\/p>\n

Compatible Coupling Flanges<\/h3>\n

The system is highly modular and designed for coupling with hydraulic pumps through dedicated flanges (component 30900.1). Interfaces are available for Group 2, Group 3, Group 3.5, Group 4 and Group 3 BOSCH pumps. Compatibility also extends to SAE A, SAE B and SAE C standards, as well as L.G. 20-35, L.G. 50, L.G. 75 and ULTRA 3PL DOWTY variants, enabling seamless integration into a wide range of hydraulic circuits.<\/p>\n
