A technical breakdown of Ningbo Nakro Intelligent Equipment's fully integrated production cells, designed to overcome traditional outer-rotor winding bottlenecks and copper fill constraints.
Electric wheel hub motors—standardized across London's micromobility, electric cargo fleet, and light electric commercial transport—operate within strict physical envelopes where magnetic flux linkage, slot-fill density, and thermal dissipation dictate tractive capability. Manufacturing these high-pole-count permanent magnet brushless (BLDC/PMSM) units demands machinery that eliminates human error during coil packing and rotor magnet bonding.
Nakro's turnkey hub motor lines utilize rigid multi-axis CNC needle winders capable of achieving copper fill factors exceeding 76% without scraping enamelled magnet wire insulation. Utilizing continuous closed-loop magnetic tensioners, our winding nozzles navigate deep, narrow outer-rotor stator slots with micron-level positional repeatability. Integrated laser stripping stations guarantee pristine termination before high-frequency pulse hot-staking onto lead terminals.
Engineering Core: Integrated MES data logging monitors dynamic winding tension, iron core stack compression force, and magnetic segment push-out shear force at each station, providing full traceability aligned with automotive TS 16949 principles.
For outer rotor assemblies, our robotic magnet insertion station solves common problems of pole skewing, air-gap unevenness, and adhesive void formation. By indexing multi-polar rotor housings against vision-calibrated optical stops, magnets are fed via pressurized pneumatic guide tracks, mechanically locked, and cured under controlled induction heating cells.

Aligning manufacturing throughput with London's rigorous clean air infrastructure, last-mile parcel networks, and transport electrification directives.
With London's Ultra Low Emission Zone (ULEZ) enforcing zero tailpipe emissions, major logistics hubs across Wandsworth, Southwark, and Hackney are replacing diesel vans with heavy-duty commercial e-cargo trikes and quads. Our production lines fabricate high-torque 250W–1000W gearless direct-drive rear hub motors that withstand 150 kg commercial payloads and continuous stop-and-start urban stopway delivery conditions.
Transport for London (TfL) has enacted strict licensing and mechanical safety standards for passenger pedicabs operating in the West End. Motors produced on Nakro systems incorporate high-pole-count stators (40–56 poles) that deliver smooth, cogging-free acceleration without gearbox vibration or maintenance downtime, providing comfortable passenger transport in pedestrian-dense areas.
Fleet operators along the River Thames logistics corridor are transitioning to Class L7e light utility quadricycles and airport apron transfer baggage carriers. Nakro lines manufacture heavy-duty 48V–96V, 3 kW to 10 kW in-wheel hub motors featuring integrated mechanical drum or disc brakes, maximizing vehicle chassis floor space for cargo volume.
How British EV OEMs and tier-1 sub-assembly contractors are mitigating supply chain risks by adopting automated manufacturing equipment.
The aggressive expansion of London's Ultra Low Emission Zone (ULEZ) to encompass the entirety of Greater London has fundamentally altered light vehicle economics. Commercial operators face severe daily penalties for non-compliant internal combustion vehicles. Consequently, demand for zero-emission delivery platforms has outpaced regional vehicle assembly capacity, creating supply bottlenecks for reliable, certified wheel hub drive units.
Historically, UK engineering firms imported finished motor units from fragmented sources. However, stringent UKCA (UK Conformity Assessed) requirements, alongside the British Standard BS EN 15194 for electrically power-assisted cycles, have introduced major compliance hurdles regarding counterfeit raw materials and unverified magnet wire thermal classes. Leading UK mobility manufacturers are responding by investing in dedicated domestic assembly cells.
By installing Nakro's automated winding, magnet insertion, and electrical validation equipment in UK manufacturing hubs (such as Park Royal in London, the West Midlands, and Oxfordshire), British OEMs achieve complete control over insulation integrity, copper purity, and magnetic field balance. This localized assembly workflow secures government automotive transformation grants while reducing overseas transit lead times from months to zero.
Our fully automated cells feature variable frequency drive (VFD) servo motors with kinetic energy recovery, cutting plant energy consumption by up to 28% compared to legacy pneumatic transfer lines—supporting London Borough net-zero corporate targets.
