Mitsubishi Electric ZKB-20BN 200Nm Magnetic Particle Brake (Made in Japan):
- Technical Specifications: Rated braking torque 200 N·m (approx. 20 kgf·m), operating coil voltage 24V DC, coil power consumption 44W (current 1.83A at 75°C), cooling method natural convection air cooling (allowable continuous thermal slip heat dissipation 300W), maximum allowable rotational speed 1,000 RPM, high-temperature spherical alloy magnetic powder, rigid shaft diameter Ø35mm with keyway, total weight approx. 21.5 kg, Product of Mitsubishi Electric Corporation Japan.
- Linear Proportional Torque-to-Current Relationship: Braking torque varies in exact linear proportion to excitation current, ensuring smooth, highly responsive continuous tension regulation.
- Constant Slip Stability for Continuous Web Tension: Delivers ultra-smooth slip torque with zero stick-slip shudder, eliminating web wrinkles, stretch, and breakage on delicate materials.
- High-Heat Resistant Spherical Alloy Magnetic Powder: Withstands intense continuous slip friction temperatures without sintering or torque decay over millions of cycles.
- Natural Cooling Aluminum Ribbed Body: Efficient heavy thermal radiator fins dissipate 300W of slip heat continuously without requiring external forced blowers.
- Long Operational Service Life: Precision magnetic gap geometry and sealed heavy-duty bearings deliver industrial multi-year reliability.
- Applications: Paper winding & unwinding stands, plastic film slitting machines, copper foil converting lines, textile looms, and wire drawing tensioners.
