Borelli 3 daNm Electromagnetic Clutch – 30900/N1 Series

Description

The Borelli 3 daNm Electromagnetic Clutch – 30900/N1 Series is a highly engineered power transmission solution designed for hydraulic applications requiring maximum engagement precision and reliability. The entire range features fully reversible mechanical components, a crucial operational advantage for integration into complex machinery.

The clutch assembly is built around a robust housing (code 30009/3), which accommodates a high-load-capacity SKF 3206 bearing (code 503206), supported by a dedicated shaft (AC30900). The sealing system includes a 30x40x7 oil seal (303040) and precision O-rings (including the D.60 variant, code 403225), essential for protecting the internal mechanisms. Power transmission is handled by a poly-V belt pulley for the electromagnetic clutch (code 4003/125PLVP), featuring a 4 PLV groove configuration. The coupling meets the most stringent technical standards through the use of a DIN 5482-A 25×22 spline profile. The mechanical assembly uses standardized high-strength fasteners, including EN 24017 M5x12 screws and TCHC UNI 5931 M6x12 socket head cap screws. The total weight is optimized at 3 kg, with a dedicated 2×2.5 electrical power cable.

Mechanical and Dynamic Performance

In terms of performance, the Borelli 3 daNm Electromagnetic Clutch – 30900/N1 Series delivers a nominal torque of 3.0 daNm and a static torque of 4.5 daNm. Dynamic torque decreases as shaft rotational speed increases: 3.2 daNm at 500 rpm, 2.8 daNm at 1000 rpm, 1.7 daNm at 1500 rpm, 1.4 daNm at 2000 rpm, 1.2 daNm at 2500 rpm, and 0.9 daNm at 3000 rpm. The device supports a maximum rotational speed of 5000 rpm.

The mechanism offers excellent response times: engagement takes 25 ms, while disengagement occurs in 40 ms. The minimum interval required between two consecutive engagements is 20 seconds.

Electrical Specifications and Power Consumption

The series is available in two voltage configurations: model 30900-1/N1, powered by 12 V DC (using coil 401203/125B), and model 30900-2/N1, powered by 24 V DC (using coil 402403/125B).

Electrical consumption values vary depending on operating temperature. At a reference temperature of 20°C, the 12 V DC version has a resistance of 7.9 Ω, a current of 2.1 A, and a power consumption of 25.2 W. At 120°C, these values change to 5.7 Ω resistance, 1.6 A current, and 18 W power consumption. Similarly, for the 24 V DC version at 20°C, resistance is 21.7 Ω, current is 1.1 A, and power consumption is 26.5 W. At 120°C, the corresponding values are 30.7 Ω, 0.8 A, and 19 W. All technical data are rated at 20°C; when operating at 120°C, the component’s overall performance decreases by 20%.
