Anyhz aluminum shell braking resistors provide reliable dynamic braking for variable frequency drives (VFDs) and servo systems from 50W to 3000W. These wirewound resistors convert regenerative energy into heat during motor deceleration, preventing VDC bus overvoltage and enabling controlled, rapid stopping of high-inertia loads.
Designed for industrial automation, CNC machine tools, cranes, elevators, and high-inertia machinery, our braking resistors feature golden anodized aluminum shells for superior heat dissipation, allowing continuous operation at 10% duty cycle with 100% braking torque. The robust construction withstands harsh factory environments including vibration, dust, and temperature extremes.
The golden anodized aluminum shell provides exceptional thermal conductivity and corrosion resistance. Unlike painted steel enclosures that trap heat, the aluminum shell acts as a heat sink, dissipating braking energy 30% more efficiently.
Wirewound construction using high-grade resistance wire wound on ceramic cores provides stable resistance values and high overload capacity.
The resistor element is encapsulated in non-combustible inorganic materials that withstand extreme temperatures without decomposition or toxic fume emission.

| Feature | Anyhz Aluminum Shell | Steel Enclosure Resistors | Ceramic Resistors | Impact on Your Application |
|---|---|---|---|---|
| Heat Dissipation | Excellent (aluminum heat sink) | Poor (steel traps heat) | Good (but fragile) | ✓ 30% better cooling, longer life |
| Durability | Rugged (vibration resistant) | Good | Poor (cracks easily) | ✓ Survives industrial vibration |
| Environmental | IP54, weatherproof | IP20-IP54 | IP20 (exposed wires) | ✓ Suitable for harsh environments |
Bottom line: Anyhz aluminum shell braking resistors offer the optimal combination of heat dissipation, durability, and safety for industrial VFD applications. Unlike cheap steel or ceramic alternatives, they withstand factory conditions while providing reliable braking performance.
★★★★★ 4.8/5 based on 423 braking resistor installations
Use our selection tables based on VFD power rating and input voltage (220V or 380V). The tables provide optimal resistance values for 100% braking torque at 10% duty cycle --suitable for most applications. For high-duty cycles (cranes, elevators), select the next higher power rating or contact us for 25%/40% ED versions.
Duty cycle (ED) is the ratio of braking time to total cycle time. 10% ED means 6 minutes braking per hour--typical for CNC, pumps, and fans. 25% ED means 15 minutes braking per hour for cranes and hoists. 40% ED means 24 minutes braking per hour for extreme applications like elevators or test stands.
Surface temperature reaches 200-250 °C at full load--hot enough to cause burns but normal for braking resistors. The golden aluminum shell dissipates heat efficiently, but maintain 100mm clearance from heat-sensitive components and ensure adequate ventilation.
