The Borelli 10 daNm Electromagnetic Clutch – Front-Mounted Type 30933 \/ 30934 Series<\/strong> is a highly reliable solution for controlling power transmission in hydraulic circuits. Carefully engineered to ensure fast, stable and precise mechanical engagement, this component is fully reversible and specifically designed to withstand intensive operating cycles in demanding industrial environments, preventing premature wear and ensuring smooth motion control.<\/p>\n

Construction and Mechanical Features<\/h3>\n

The main body of the unit consists of a rigid housing containing a transmission shaft with a spline profile compliant with the DIN 5482 35×31 standard. Rotational performance relies on two high-efficiency SKF 6009 2RS radial bearings, which provide excellent axial and radial stability while minimizing operating friction. The robust and compact assembly has a total weight of 5 kg. Its structural configuration includes a base flange optimized for Group 1-2 pumps, offering extensive mounting versatility. The core operating component is the front-mounted electromagnetic clutch combined with a dedicated coil, ensuring direct engagement with minimal response delay and energy loss.<\/p>\n

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

Mechanical torque transmission performance is carefully calibrated to accommodate different rotational speeds while maintaining operating efficiency. The clutch delivers a nominal torque of 7.8 daNm and a static torque of 12.5 daNm. Under dynamic load conditions, transmitted torque varies according to operating speed: starting from a peak of 8.5 daNm at 500 rpm, it progressively decreases to 7.0 daNm at 1000 rpm, 4.2 daNm at 1500 rpm, 3.5 daNm at 2000 rpm, 2.7 daNm at 2500 rpm, and finally 2.5 daNm at 3000 rpm. The unit supports a maximum operating speed of 5000 rpm. Mechanical response times to electrical signals are extremely short: clutch engagement takes just 25 milliseconds, while disengagement requires 40 milliseconds. A minimum interval of 20 seconds between consecutive engagements is specified to protect the integrity of the system.<\/p>\n

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

The unit is safely powered through a dedicated two-core electrical cable with a 2×2.5 cross-section. The range is available in two specific voltage configurations to meet standard system requirements: the 30933 Series is designed to operate at 12 V DC, while the 30934 Series requires a 24 V DC power supply. Electrical consumption is closely linked to operating temperature. At the reference temperature of 20\u00b0C, the 12 V version (4.00 Ohm resistance) draws 3.33 A with a total power consumption of 40.00 W, while the 24 V version (20.00 Ohm resistance) draws 1.26 A with a power consumption of 30.30 W. Diagnostic tests show that at a demanding operating temperature of 120\u00b0C, overall nominal performance naturally decreases by 20%. At these extreme temperature levels, internal electrical resistance increases significantly (from 4 to 5.6 Ohm for the 12 V circuit and from 20 to 28 Ohm for the 24 V configuration), resulting in a corresponding measurable reduction in current consumption to 2.00 A and 0.77 A, respectively.<\/p>\n

Hydraulic Compatibility and Flange Configurations<\/h3>\n

To ensure seamless, modular integration into different hydraulic circuits without requiring custom modifications, the entire 30933 and 30934 Series range can be configured with various interface flanges. The available coupling options include standardized connections for Group 2 BOSCH, Group 3 and Group 3 BOSCH pumps, as well as internationally recognized SAE A and SAE B connections.<\/p>\n
