Technical Specifications‌

• Series: MDB (Magnetic Particle Brake)
• Size designation: 5
• Torque: proportional to input current, independent of shaft speed
• Coil voltage: 24 VDC class (DC operated)
• Mounting: Shaft or flange mounting
• Cooling: Natural or fan cooling depending on duty
• Construction: Self-contained, with no friction surfaces

‌Product Series‌

Part of the Deltran / Warner Electric magnetic particle brake range, which spans a wide torque range and is designed for tension control, load simulation, cycling/indexing, and soft starts and stops.

‌Functional Features‌

• Torque to current is almost linear, allowing very accurate control
• Fast and precise torque adjustment
• Constant torque independent of slip speed
• No wearing parts because there are no friction surfaces
• Unaffected by changes in atmospheric or environmental conditions
• Compact design with a high torque-to-size ratio and low power consumption
• Smooth operation at very low speeds

‌Working Principle‌

Magnetic powder fills the gap between the input and output members. When the coil is energized, the magnetic field aligns the powder particles into chains that transmit torque between the rotor and the stationary member. The transmitted torque is proportional to the excitation current, providing controllable braking torque.

‌Application Scenarios‌

• Unwind and rewind tension control
• Load simulation
• Cycling and indexing
• Soft starts and stops
• Paper, film, and foil converting equipment

‌Installation Requirements‌

Can be mounted in various orientations with shaft or flange mounting. Ensure correct alignment and adequate cooling for the applied slip power. Use the specified DC excitation voltage.

‌Precautions‌

• Do not exceed the rated slip power, as excess heat reduces life
• Provide adequate heat dissipation in continuous-slip duty
• Verify the excitation current and torque curve for the specific application
• Keep the magnetic powder sealed and protected from contamination
