BLDC & AC motors for HVAC equipment
ReputeCo designs and builds brushless DC and AC fan motors for dehumidifiers, air purifiers, exhaust fans, air curtains, range hoods and ventilation units. Integrated drivers, 6–400 W, custom shafts and windings — supplied from our own factory in Zhongshan, China.
BLDC fan motor architecture: interior rotor, concentrated winding stator, integrated control PCB and die-cast housing.
Product range
Choose the platform that matches your appliance: integrated BLDC for variable speed, 310 V BLDC for high static pressure, or AC capacitor motors for fixed-speed cost control.
6–48 W · integrated driver
Mains or 12/24 V DC input, built-in power and control board, PWM or analog speed control, 30 dB(A) noise class. For exhaust fans, purifiers and dehumidifiers.
200 W · 94 mm stator
Runs directly on the rectified 310 V DC bus. Lamination heights from 20 to 35 mm cover low-noise airflow and high static pressure blowers.
30–400 W · capacitor run
Single-phase capacitor motors with copper or high-temperature aluminium windings. Fixed-speed reliability at a competitive BOM cost.
Why ReputeCo
Most of our work starts with a drawing, a test target or an existing motor that needs to be cheaper, quieter or controllable. The four points below are what that work usually depends on.
Inside the factoryPower board, control board and firmware are developed with the motor, so PWM thresholds, protection limits and speed curves are matched — not adapted afterwards.
Shaft, flange, lead wire, connector, voltage, winding and rotation direction are configurable on existing platforms, which keeps prototype cost and lead time low.
Performance bench, temperature-humidity chamber, dielectric tester, noise screening and XRF material analysis are all in one plant, so test data comes with the lot.
Five assembly lines, ten winding machines and 300,000 pcs/month capacity under ISO 9001:2015, with a dated production plan for every order.
Applications
Each application has its own duty cycle, air path and acoustic target. These notes start from the appliance, then narrow to a motor platform.
Continuous duty, moist air path, low noise
Filter pressure drop, PWM, 30 dB(A)
Long running hours, compact housing
Heat, grease, high static pressure
Dual shaft, continuous airflow
Condenser fans, ventilation, coolers
How a custom motor gets built
The same four stages apply to a new BLDC platform and to a variant of an existing AC motor. Each stage ends with a document you can approve.
We check voltage, duty, airflow, static pressure, shaft drawing and acoustic target, then confirm feasibility and the nearest existing platform.
Samples are built with the specified winding and shaft, then tested for speed, power, temperature rise, dielectric strength and noise.
You validate the motor in the finished unit; we adjust the speed curve, mounting or protection limits before the tooling is frozen.
Production runs with lot testing and dated delivery plans; drawings, test reports and compliance files are archived per shipment.

Engineering notes
Selection guides, comparison tables and failure analysis written for equipment designers.
Custom BLDC projects fail on missing inputs more often than on design. What to send, the six development stages, the validation tests and the documents to expect.
A noise complaint arrives as one symptom but usually has several possible causes. A fixed isolation order separates bearing, balance, commutation, resonance, mounting and airflow.
Air purifier motors are sized by the pressure at end of filter life, not by clean-filter airflow. A guide to the pressure budget, closed-loop control and a 30 dB target.
