Borelli 50 daNm Electromagnetic Clutch – 30940/SF / 30941/SF Series

Description

Construction Features and Operating Principle

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.

Dynamic Performance and Response Times

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.

Electrical Consumption and Thermal Specifications

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°C, electrical resistance is 1.81 Ω, current consumption is 6.60 A, and power consumption is 80.00 W. At 120°C, power consumption decreases to 56.00 W. For the 24 V model at 20°C, resistance is 7.40 Ω, current is 3.25 A, and power consumption is 78.00 W (54.60 W at 120°C). All technical specifications refer to an operating temperature of 20°C; at 120°C, performance decreases by 20%.

Compatible Coupling Flanges

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.
