We Make Electric Motor and Exhaust Fan
We provide customized electric motors and ventilation fans with various electrical parameters to meet your specific needs.
IE5 BLDC Motors (220V/380V, 370W-2200W/0.5-4hp). IP66 rated, featuring RS485 and 0-10V stepless speed control. Optimized for negative pressure fans, air coolers, and agricultural ventilation (greenhouse & poultry).
Our agricultural fans (AC/EC, 0.37kW–3.5kW) feature FRP or galvanized steel housings and deliver air volumes up to 93,000 m³/h, supporting RS485 and 0-10V DC control. They are ideal for industrial ventilation and livestock farming (poultry, swine, and greenhouses).
Our BY (Direct Drive) and BYJ (Geared) PM Stepper Motor series provide precision motion solutions ranging from high-frequency positioning to high-torque drive, ideal for printers, HVAC louvers, security cameras, and more.
High-torque density frameless motors (25mm-114mm OD). Featuring a compact inner rotor structure with 0.05-30N·m torque and 15-20,000rpm speed range. Ideal for robotic arms, quadruped/humanoid robots, and smart agricultural steering.
Integrated Robotic Joint Modules available in 10.36 and 20.125 gear ratios. Featuring 24V/48V rated voltage, IP65 protection, and single encoder feedback, they deliver 6N·m to 10N·m rated torque for collaborative arms, service robots, and exoskeletons.
Our 12V/24V small brushless DC motors support adjustable speeds from 300rpm to 3000rpm. They feature low noise, high efficiency, and long life, making them suitable for pedestal fans, air purifiers, humidifiers, lawnmowers, and more.

Direct Factory Supply, More Predictable Lead Time
Automated ProductionFully automated winding and assembly lines eliminate manual operation errors. With a daily capacity of 600,000 units, we ensure stable delivery for high-volume orders.
Precision Component ManufacturingEquipped with integrated turn-mill CNC lathes, gear hobbing machines, and gear shaping machines, we manufacture all core gear components in-house. By strictly controlling mechanical tolerances at the source, we achieve comprehensive quality oversight from individual parts to the finished product.
Life and Performance TestingEvery electric motor model must undergo life and performance testing in our lab, simulating real-world operating conditions. This ensures that every unit delivered to you withstands the rigors of long-term use.
Proven Experience Trusted by Global Industry Leaders
With over 3,000 global projects and exports to 100+ countries, we are a long-term partner of Fortune 500 companies such as Gree and Midea. In the application fields of smart home and HVAC, industrial and agricultural ventilation, industrial equipment and automation, we have accumulated mature experience. We can quickly understand different working conditions and technical requirements, reduce repeated communication, and accelerate project implementation.
Manufacturing & Quality Assurance
Our factory combines Turn-Mill CNC multitasking, gear hobbing, and shaping with core electric motor manufacturing techniques to ensure both precision and durability. By integrating automatic winding (for resistance consistency), VPI (Vacuum Pressure Impregnation) (for enhanced insulation in harsh environments), and automatic balancing (for ultra-quiet operation), we maintain strict control over every performance metric. From frameless torque motors to high-power EC fans, all products are rigorously validated using our dynamometer systems and airflow test chambers, providing global customers with high-efficiency, reliable, and high-precision motion solutions.

What Our Happy Client Say
5-star reviews show our customers trust us.
“We tried several suppliers, but none could match our equipment specs. After we talked, their team quickly gave us a custom solution. The sample passed testing on the first try, which saved us a lot of development time.”
Mark StevensTechnical Manager“We used MAINTEX EC fans for a large-scale poultry farm project. We needed low energy consumption and high stability. Their team helped us optimize the electric motor specifications and advised on fan installation. Since installation, energy costs have dropped significantly, and the system is much more stable. This has significantly reduced our maintenance costs.”
Thomas FischerOperations Manager“We used to have problems with stepper motors being inconsistent between batches, which affected our air conditioners. After working with MAINTEX, they provide test reports for every batch. Now I can feel confident giving them our orders.”
James WilsonQuality Engineer“For our joint module project, we needed high motor precision and specific gear ratios. Their engineers gave us great advice on choosing the right model and technical support. They even helped optimize our original design drawings, and the results perfectly met our expectations.”
