III. Structure and Core Features
- Lightweight aluminum casing design
- It features an aluminum alloy die-cast housing, offering excellent heat dissipation, lightweight construction, and corrosion resistance, making it suitable for humid or light‑industrial environments.
- Fully enclosed protective structure
- With an IP54/IP55 protection rating, it effectively prevents the ingress of dust and water droplets, making it suitable for dusty and humid workshop environments.
- Low noise, low vibration
- Employing an optimized stator winding design and dynamic balancing process, the unit achieves operating noise levels of ≤60 dB, with vibration ratings meeting the national Class N standard, ensuring smooth and stable operation.
- High reliability, maintenance-free
- Brushless and commutator-free design ensures no wear‑prone components during prolonged operation, with a service life of over 10 years when operated under S1 duty cycle.
- Wide compatibility
- It can directly drive general-purpose loads such as small machine tools, food-processing machinery, textile equipment, water pumps, and fans, and can also be used in conjunction with gear reducers.

VI. Precautions for Use and Selection
- Installation method : The illustration shows a B5 flange‑mounted vertical installation, suitable for vertical mounting applications; for horizontal mounting, please select models B3 or B35.
- Load matching The motor’s rated power should be 1.1 to 1.2 times greater than the load’s required power to prevent prolonged operation under overload conditions.
- Voltage requirements The operating voltage fluctuation must be kept within ±5%; otherwise, the motor’s lifespan and efficiency will be affected.
- Environmental constraints Operating ambient temperature: -15°C to 40°C; altitude not exceeding 1,000 m; derating is required at higher altitudes.
