What is the difference between a hairpin motor and a conventional round-wire motor?
Hairpin windings achieve a higher slot fill ratio than round wires, giving higher power density and efficiency in the same volume. Arts-power hairpin PMSM motors reach peak efficiency above 95% with a 10–15% wider high-efficiency range, low thermal fade and millisecond-level dynamic response.
Is the motor in the Aoxiang EA5 made by you?
Yes. The hairpin PMSM motor and controller in the Aoxiang EA5 powertrain are developed and manufactured by Suzhou Hetaixinrui Technology (Arts-power). The vehicle OEM markets the powertrain under its own brand; fitment details are subject to the OEM’s official channels and the actual vehicle.
How does the F30 High-Speed differ from the standard F30 powertrain?
The F30 High-Speed focuses on higher top speed (55 km/h) at the same payload with better power efficiency. It uses a hairpin PMSM — higher slot fill ratio, wider high-efficiency range and millisecond-level dynamic response — while the standard F30 uses a different type of powertrain. For heavy daily loads, long-distance transport or speed-demanding scenarios, the High-Speed version is stronger in efficiency, climbing and range.
How does it perform on full-load climbing and range?
Taking the F30 High-Speed as an example, the vehicle OEM publishes a full-load range of ≥140 km and a top speed of 55 km/h, with hill-start assist and anti-rollback as standard. The hairpin motor delivers high direct torque with low thermal fade at sustained high power, making heavy-load climbing easier. Actual performance depends on payload, road conditions and battery configuration.
Do you offer custom motor development?
Yes. Our segmented motor design allows the axial length to be adjusted per vehicle platform; torque and speed are freely selectable and controller parameters are configurable.
Which communication protocols do your controllers support?
Standard CAN, UDS diagnostics and OTA, plus one-wire protocols. We also integrate cluster, controller, battery BMS and VCU communication schemes.
Do your products meet automotive functional safety requirements?
Our controllers use a scalable ASIL-B functional safety architecture to prevent unintended vehicle torque. Critical functions follow the automotive V-model, with ±3 N·m torque estimation accuracy and complete fault recording.
What is your annual production capacity?
We operate our own hairpin stator line in Suzhou Industrial Park (2,500 m²) with an annual capacity of 100,000 units. Lead times depend on model and order quantity.
