Product Specifications

Technical details and manufacturing context for Industrial Electromagnetic Clutch-Brake Unit

Definition

The Industrial Electromagnetic Clutch-Brake Unit is a self-contained electromechanical device used to control motion in automated manufacturing processes. It provides rapid engagement and disengagement of rotating components, enabling precise indexing, positioning, and emergency stopping. This machine is essential for applications requiring controlled acceleration, deceleration, and torque limitation in electrical equipment production lines. Its compact design allows integration into various industrial setups without complex mechanical linkages. The unit operates on a 24 VDC supply (±10%) and is rated for continuous torque from 50 to 2000 Nm, with response times between 30 and 80 ms. Maximum speed ranges from 1500 to 3000 rpm, and power consumption during engagement is 20 to 150 W. Shaft diameters accommodate 20 to 80 mm, and the unit weighs between 10 and 150 kg depending on torque rating and size. Operating temperature is -20 to 60°C, with derating above 40°C. Enclosure protection is IP54 to IP65 per IEC 60529, suitable for dusty or wet environments. The friction material is sintered metal for high wear resistance, and the coil insulation class is F per IEC 60085, allowing a 155°C hot spot. The air gap between friction surfaces should be adjusted to 0.2 to 0.5 mm to maintain torque and compensate for wear. These values are reference ranges; verify model-specific specifications with the legal manufacturer or supplier before selection or installation.

Working Principle

The unit uses electromagnetic fields to engage friction discs for torque transmission (clutch) and braking action. When an electrical current is applied to the coil, it generates a magnetic field that pulls the armature against the friction discs, creating friction to transmit torque or to stop rotation. The control signal determines whether the clutch or brake is engaged, allowing rapid switching between drive and stop modes. The response time depends on the coil inductance and mechanical inertia. The air gap must be maintained within specified limits to ensure consistent performance.

Frequently Asked Questions

What is the typical response time of this clutch-brake unit?

The response time from signal to engagement or disengagement is typically 30 to 80 ms, depending on the model and operating conditions. Verify the specific value for your application with the manufacturer.

What voltage is required for operation?

The unit requires a DC supply of 24 VDC ±10%. Ensure your control system provides this voltage within the specified tolerance.

How do I maintain the air gap?

The air gap between friction surfaces should be checked periodically and adjusted to 0.2 to 0.5 mm to maintain proper torque transmission. Wear on friction discs increases the gap, so adjust as needed.

What environmental conditions can the unit withstand?

The unit operates in ambient temperatures from -20°C to 60°C, with derating above 40°C. It has an IP rating of IP54 to IP65 per IEC 60529, making it suitable for dusty or wet environments. Confirm the exact IP rating for your model.
