The draught fan motor is the core power of fan equipment. Our company's three-phase asynchronous motor is custom-designed specifically for fan operating circumstances. It offers the core advantages of 'high efficiency and energy saving, stable and durable performance, and strong adaptability.'This motor provides reliable power support for various fan systems across industrial ventilation, environmental protection, and HVAC applications.
When it comes to key specs, this motor covers a really wide power range, from 0.75kW all the way up to 315kW. Whether you're using a centrifugal fan, an axial fan, or a Roots blower, there's pretty much a model that fits. The rated voltage meets industrial standard in every country. The rated speed offers several options-2950rpm, 1460rpm, 950rpm-to ensure the speed output matches fan load. In addition, the motor has an IP55/F(155℃) class, can running in outdoor humid environments or longterms high-temperature circumstances.
The structure is designed with the fan's installation and operating characteristics in mind. You can install it in a B3, B5, B14, or B35 mounting. It can directly connect to standard fan mounting interfaces, reducing on-site modifications. The shaft extension is high-strength 45# steel, with diameter tolerance under 0.02mm. It has a standard keyway design, connecting tightly with the fan impeller. This stops it from loosening or slipping when the fan works. The motor uses forced ventilation cooling. It cools down fast, even when the fan runs at full load.
This draught fan motor has an energy-saving iron core and copper winding, with efficiency rating IE3 or better. Compared to traditional motors, it saves 10%-15% energy, cutting a lot of electricity costs over long-term use. It has great starting performance, with a starting current ≤ 6 times the rated current. Using star-delta or soft starters can help avoid power surges during startup. It works with 5-60Hz variable frequency adjustment, with a wide, stable speed range. You can control the motor speed precisely based on airflow, so it fits different working conditions. The junction box has a printed Y/Δ wiring diagram for quick and easy wiring. Routine maintenance only requires cleaning the heat sink on the casing; the bearings require no additional lubrication.
This special draught fan motor has passed ISO9001 quality system certification and the mandatory 3C certification, going through 8 inspection steps from raw material purchase to finished product. Whether it's for factory workshop ventilation, environmental engineering exhaust treatment, or air conditioning and ventilation in malls and office buildings, it's reliable and easy to pair with, making it a perfect buddy for your fan system.
