The Borelli 3 daNm Electromagnetic Clutch – 30900 Series is an advanced technical solution for managing power transmission in hydraulic circuits and industrial mechanical systems. Engineered to ensure maximum operating efficiency, this reversible device features a robust construction, a total weight of 3 kg, and precise coupling tolerances, supported by a DIN 5482 – A 25×22 spline profile with a 25.4 H7 diameter.<\/p>\n

Torque Specifications and Dynamic Performance<\/h3>\n

The performance of the Borelli 3 daNm Electromagnetic Clutch – 30900 Series is based on a nominal torque of 3.0 daNm and a static torque of 4.5 daNm. The component’s dynamic response varies according to rotational speed, providing the flexibility required for different mechanical applications. Specifically, the dynamic torque delivered is 3.2 daNm at 500 rpm, progressively decreasing to 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 finally reaching 0.9 daNm at 3000 rpm. The unit can withstand a maximum rotational speed of 5000 rpm.<\/p>\n

Construction Features and Components<\/h3>\n

The spare parts diagram highlights the use of high-quality components designed to ensure long-lasting clutch performance. The assembly includes an SKF 3206 bearing, 30x40x7 oil seals, precision O-rings (D.60), and UNI 6604 5x5x20 parallel keys. The main transmission element consists of an electromagnetic clutch pulley featuring a Section A groove. Structural fastening is ensured by standardized hardware, including EN 24017 M5x12 screws and UNI 5931 M6x12 socket head cap screws. The system is completed by the dedicated AC30900 shaft, the UNI 7436-25 retaining ring, and the housing.<\/p>\n

Electrical Consumption and Power Supply<\/h3>\n

The device offers extremely fast response times for hydraulic applications, with an engagement time of 25 ms and a disengagement time of 40 ms. The minimum required interval between two consecutive engagements is 20 seconds. Electrical power is supplied through a dedicated 2×2.5 cable. Electrical consumption varies depending on the rated voltage and operating temperature. At 20\u00b0C, the 12 V DC model consumes 25.2 W (2.1 A), with a resistance of 5.7 \u03a9, while at 120\u00b0C, power consumption decreases to 18 W (1.6 A). The 24 V DC model requires 26.5 W (1.1 A) at 20\u00b0C, with a resistance of 21.7 \u03a9, decreasing to 19 W (0.8 A) at the operating temperature limit of 120\u00b0C.<\/p>\n

Operating Parameters and Thermal Factors<\/h3>\n

A critical factor in correctly sizing the system is the effect of temperature on electromagnetic coil performance. All nominal technical specifications provided by the manufacturer are calibrated at a reference temperature of 20\u00b0C. Under demanding operating conditions, when temperatures reach 120\u00b0C, the clutch undergoes a natural thermal performance reduction, resulting in a 20% decrease compared to optimal nominal values.<\/p>\n
