secondary air fan motor
- Product Description
Secondary Air Fan Motor - High-Performance Industrial Ventilation Solutions
You need a secondary air fan motor that works consistently even when conditions are tough for your business processes that need reliable air flow and ventilation. Tellhow Shenyang Electric Machine Co., Ltd. provides business-level motor solutions designed to work efficiently in the metalworking, power generation, and environmental protection fields. Our motor line has welded steel frames that make the structure more rigid, F-class insulation systems with VPI-treated windings, and copper-alloy rotors that keep vibrations to a minimum while extending the life of the motor. With power levels from 160 kW to 35,000 kW and voltage flexibility from 690V to 15,000V, we can give you flexible options. Our 190,000-square-meter factory can also produce 8 million kW of power every year.
Why Choose Our Industrial Fan Motors
Built for Demanding Environments
Every day at work, you have to deal with tough situations. That's why we made these motors strong enough to handle them.
Our motors work reliably in tough industrial settings and temperatures that go from freezing to boiling. When compared to cast frames, the welding steel design is more rigid. This means that your tools will shake less and have bearings that last longer.
The F-class shielding method keeps your money safe. When double-layer coils are treated with VPI, a shield that doesn't let water through is made. Even when things get tough, your machine keeps going.
Energy Efficiency That Reduces Your Costs
How much power you use has a direct effect on your bottom line. Compared to regular motors, our high-efficiency design saves 15–20% of the energy they use.
Losses are kept to a minimum by the improved magnetic circuit structure. Copper and copper-alloy blades carry electricity better than metal ones. You'll be able to tell because of the change in your regular bills.
Modern ways of cooling (IC01, IC611, IC616, IC81W, and IC86W) keep temperatures steady. When the working temperature is lower, the system works more efficiently and parts last longer.
Flexible Configuration Options
There are different needs for each purpose. We can change a lot about our services to fit your needs:
160 kW to 35,000 kW of power
You can choose from 2 to 24 poles to finetune the speed.
From 690V to 15,000V voltage range.
The frequency can be 50Hz or 60Hz.
Different levels of security: IP23, IP44, IP54, IP55
We can help you whether you need a small 160 kW unit or a huge 35,000 kW system. Our engineering team can change the insulation classes, change the sizes of the structures, and set up motors so that they meet your exact needs.

Advanced Engineering Features
Superior Rotor Technology
The rotor of your motor decides how well and how reliably it works. Based on frame size, we use two different methods.
Copper and copper-alloy blades are the best for bigger frames (H>500) because they carry electricity very well. These materials are better than others at resisting heat growth. As a result? Less shaking, better function, and not much upkeep is needed.
Smaller frames (H≤500) have metal wheels that are better at getting rid of heat. When they are overloaded, these wheels don't get damaged. When demand spikes unexpectedly, your secondary air fan motor responds without missing a beat.
Intelligent Thermal Management
Too much heat will shorten the life of a motor. Our plans for cooling systems take this problem into account in every way.
Different installation conditions can be accommodated by different cooling setups. Designs with open vents (IC01) work well in clean areas. Closed-loop systems (IC81W, IC86W) keep dirty air from getting inside. Options for forced air (IC611, IC616) handle cases with a lot of work.
The better heat transfer keeps the temperatures of the windings within safe limits. This makes the padding last longer and keeps it from breaking down too soon.
Precision Manufacturing Standards
On the factory floor, quality starts. During production, our 500-million-RMB plant uses high-precision manufacturing methods.
At several stages, the dimensions of each motor are checked. Proper air gaps and bearing placement are made possible by precise assembly. When you need steady performance over decades of use, these factors matter.
The unique magnetic circuit designs increase the flux intensity while lowering the loss. For each amp of incoming power, you get more force.
Applications Across Industries
Power Generation Facilities
Thermal power plants depend on continuous air circulation. Our motors drive induced draft fans, forced draft fans, and secondary air systems. The wide voltage range accommodates different plant configurations. Frequency-controlled options integrate seamlessly with modern control systems.
Metallurgical Operations

Frequently Asked Questions
Q:What makes your product different from standard industrial motors?
A:Our motors incorporate several specialized features. The welded steel frame construction offers superior rigidity compared to cast alternatives, reducing vibration transmission to connected equipment. F-class VPI-treated windings provide enhanced moisture resistance critical in humid environments. Copper-alloy rotors in larger frame sizes deliver lower electrical losses and better thermal performance. These engineering choices result in longer service intervals and reduced total cost of ownership.
Q:Can these motors operate in explosive atmospheres?
A:Yes, we manufacture explosion-proof variants that comply with hazardous location requirements. These specialized units feature modified enclosures, cable glands, and internal protection to prevent ignition sources. If your application involves combustible dust or flammable gases, specify this requirement during the quotation process so we can recommend appropriate models.
Q:How do I select the correct protection grade for my application?
A:Protection grade selection depends on your environmental conditions. IP23 suits clean indoor installations with minimal dust. IP44 provides splash protection for light industrial use. IP54 prevents dust accumulation in dirtier environments. IP55 offers the highest protection against both dust and water jets, ideal for outdoor installations or wash-down areas. Consider your exposure to moisture, particulates, and cleaning procedures when specifying.
Q:What voltage and frequency options work for international installations?
A:Our motors accommodate voltage ranges from 690V to 15,000V and operate on either 50Hz or 60Hz power systems. This flexibility allows deployment across different global electrical standards. For specialized requirements outside these ranges, our engineering team can develop custom solutions. Always verify local electrical specifications before finalizing your motor selection.
Q:Do you provide variable frequency drive compatibility?
A:Absolutely. Our frequency-controlled motor variants feature enhanced insulation systems designed for VFD operation. The winding configuration handles the voltage spikes inherent in PWM inverter outputs. We can also supply motors specifically optimized for low-speed operation under VFD control, maintaining adequate cooling at reduced frequencies. Consult with our technical team about your specific drive system for optimal compatibility.
Q:What warranty coverage comes with these motors?
A:Standard warranty terms cover manufacturing defects and material failures under normal operating conditions. Coverage duration and specific terms depend on motor size and application. We extend support beyond warranty periods through our global service network. Proper installation, operation within rated parameters, and adherence to maintenance schedules ensure maximum reliability and warranty protection.
Q:Can you manufacture motors to custom specifications not in your standard catalog?
A:Yes, our ODM/OEM capabilities support extensive customization. We modify power ratings, adjust mounting configurations, change shaft dimensions, upgrade insulation classes, and adapt cooling systems to match unique requirements. Our engineers work from your specifications or collaborate on design optimization. Minimum order quantities for custom variants depend on the extent of modifications required.
Q:How long does delivery take for standard versus custom motors?
A:Standard catalog models typically ship within established lead times based on current production schedules. Custom specifications require additional engineering and manufacturing time. During the quotation process, we provide realistic delivery estimates based on customization complexity and production queue. For critical deadlines, express manufacturing may be available for additional cost.
