Controlled sourcing
Components are selected and purchased by our own engineers, not left to a subcontractor.

01 · R&D Center
Detection Machine
Every motor and controller is verified on our in-house detection line before it leaves the factory — from loaded run-in and performance testing to environmental aging and full parameter inspection.
✓
Loaded run-in
Every motor is run under load to confirm torque, speed and temperature behaviour before release.
✓
Performance testing
Power, efficiency and no-load current are measured against the specification of each order.
✓
Environmental aging
Controllers and motors face heat and continuous-run aging to expose early-life failures.
✓
Full parameter inspection
PC-logged parameter records complete the check before a unit leaves the factory.
Custom voltage, power and control features are developed and validated on these benches, so customized products reach customers already proven — not experimented on site.
02 · Electronics Workshop
SMT Placement Machine
Our self-owned SMT placement lines produce the controller boards used in our motors and complete system sets in-house, ensuring consistent, reliable product quality for all clients.
Repeatable soldering
Automated placement and reflow keep every controller board consistent from batch to batch.
Full traceability
Board production, test data and motor matching stay inside one factory and one quality system.
In-house SMT means full control over component sourcing, soldering quality and traceability — the foundation of every reliable controller we ship.
03 · Built to Spec
Custom Development
Our R&D centres exist to create customized products and features for our customers. Tell us what the vehicle has to do, and we develop and validate the motor and controller around it.
Voltage & power
Custom voltage platforms and rated power targets developed for your vehicle and market.
Control features
Controller logic, throttle mapping and protection parameters tuned to your application.
Mechanical fit
Axle, brake and wheel interfaces adapted so the motor drops into your existing frame.
Complete system sets
Motor, controller, harness and display delivered and validated as one matched package.
Frequently asked questions
Do you have your own R&D centres?
Yes. We operate our own R&D (Research and Development) centres for motors and controllers, so customized products and features are developed and validated in-house before they reach customers.
Are the controller boards made in your own workshop?
Yes. Our self-owned SMT placement lines produce the controller boards used in our motors and complete system sets in-house, giving us full control over component sourcing, soldering quality and traceability.
Is every motor tested before shipment?
Every motor and controller is verified on our in-house detection line before it leaves the factory — from loaded run-in and performance testing to environmental aging and full parameter inspection.
Can you build motors or controllers to our specification?
Yes. Tell us your application and requirements and our R&D team replies with a tailored proposal, price, MOQ and lead time within 24 hours (Mon–Sat).
