3. Key Features
IE3 High Efficiency and Energy Saving: 2-pole high-speed design saves 12–18% energy compared to IE1/IE2, offering low long-term operating costs.
BE05 Reliable Braking: 5 Nm holding torque with fast response and low noise; MSW manual release ensures safe and convenient maintenance.
AVS1 Frequency Converter-Specific Cooling: Independent fan prevents overheating at low speeds from 0–100 Hz, ideal for prolonged high-speed or variable-speed operation with frequency inverters.
High-Speed Stability: Standard speed of 2800 rpm with low vibration and low noise ≤72 dB, suitable for high-speed spindles and conveyor lines.
Lightweight and Durable: Aluminum housing provides light weight and excellent heat dissipation; imported bearings and seals ensure long service life and maintenance-free operation.
IP54 Protection: Resistant to dust, moisture, and splashing water, making it highly adaptable to industrial environments.
Modular and Easy Integration: Perfectly compatible with SEW frequency inverters (MC07B/MOVITRAC) and R/K/F/S series gear units.
