Technical Support From Controller Selection to Production
VIREOMOTOR supports three-phase BLDC controller projects from selection and motor matching to customization, testing, production and troubleshooting—for ventilation equipment, cooling fans and water pumps.
Before You Select a Controller
Start With the Motor and Application Requirements
Provide your motor datasheet and application requirements. We can review controller compatibility before the project moves forward.
Compatibility Review
Confirm the Electrical and Application Fit
The same power rating does not guarantee compatibility. Review motor parameters, operating load and control needs together.
Electrical Matching
Voltage, power, current and motor electrical characteristics.
Speed Matching
Rated RPM, operating speed range and speed-control needs.
Load Matching
Startup load, current, speed response and controller temperature.
Duty Cycle
Continuous and intermittent operation may create different requirements.
Application Matching
Fans and pumps have different load and control characteristics.
Best Starting Point
Send the complete motor datasheet whenever possible.
Motor + Controller + Load
Compatibility depends on the complete operating system.
When Standard Is Not Enough
Adapt the Controller to Your Equipment
If a standard controller does not fit, we can assess electrical, hardware and software customization based on technical feasibility.
Electrical Customization
Voltage, power, current, torque requirements and power-stage configuration.
Hardware Customization
PCB size, connectors, wiring and component configuration.
Software Customization
Startup, speed control, operating logic and application functions.
Protection Requirements
Protection strategy can be evaluated according to the motor, equipment and environment.
Thermal Management
Heat, airflow, installation and operating temperature.
Communication & Integration
Communication requirements can be evaluated according to the actual equipment architecture.
Engineering Development
Support Beyond the First Working Prototype
A working prototype may still need tuning and application validation before production.
Prototype Evaluation
Where applicable, evaluate the controller with the intended motor.
Motor Tuning
Startup, speed, load response, noise and thermal performance.
Equipment Integration
Evaluate controller behavior within actual or representative equipment.
Control Logic
Start/stop commands, speed, operating modes and control logic.
Communication Integration
Provide the actual system and interface requirements where communication is required.
Parameter Optimization
Motor-control parameters can be refined according to engineering evaluation.
From Sample to Production
Carry the Confirmed Controller Configuration Into Manufacturing
Engineering, manufacturing and quality processes help carry a validated controller into repeatable production.
Hardware, software, motor-control parameters and project-specific requirements.
Verify intended controller functions according to the confirmed specification.
Evaluate electrical behavior against approved project requirements.
Inspection procedures support consistency before product release.
Engineering can support analysis if a production issue is identified.
Findings can support parameter, hardware, software and production-process review.
Technical Problem Analysis
Give Us the Symptoms — and the Operating Conditions
Share the symptoms, motor data and operating conditions to support accurate troubleshooting.
Recommended Information
Startup Issues
Tell us whether the motor does not start as expected, starts inconsistently, shows abnormal behavior under load or requires different startup behavior.
