What makes drone motor assembly different?

Drone motors require compact size, light weight, precise dynamic balance and high power density.

Can Jiuju lines produce small drone motors?

Yes, our compact stations and fast changeover are designed for small-batch, multi-variant UAV motors.

Automated assembly line solutions for drone motors

The automated production line for UAV motors is a specialized production facility for customized high-performance motors for Unmanned Aerial Vehicles (UAVs). The line integrates advanced automation technology, precision engineering and stringent quality control systems to ensure that the motors meet the stringent requirements of UAV applications, including core features such as lightweight design, high torque, high energy efficiency and superior reliability.

Customization Process

Customized to the thrust-to-weight ratio and consistency requirements of UAV motors; magnet insertion, dynamic balancing, thrust and torque testing are all redesigned. Seven stages, each with defined deliverables and customer sign-off points.

1
Requirement review
& concept design
7–15 days
Technical proposal
2
Technical freeze
& contract
3–7 days
Technical agreement
3
Design & build
in-house commissioning
30–60 days
Drawings · programs
4
FAT
factory acceptance
3–5 days
Acceptance record
5
Site installation
& SAT
5–10 days
SAT report
6
Production validation
3–10 days
Validation report
7
Final acceptance
& handover
2–3 days
Manuals · spares

Total lead time is typically 45–120 calendar days, with build and in-house commissioning accounting for the largest share. Once the design is frozen, changes to core process parameters (size, cycle time, number of stations) cascade into mechanical, electrical and layout changes and may extend the schedule by more than 30% — technical freeze requires written customer confirmation.

Program Advantages

Aiming at the characteristics of small volume and high integration of micro brushless motor, UAV motor automation production line solution covers the whole process of stator winding, rotor magnet press-fitting, stator-rotor assembly and performance testing, integrating multi-axis servo winding, vision + force control dual-guidance assembly, micron-level dispensing and other processes, and solving the pain points of assembly deviation of tiny parts and disorganization of lineups with the help of real-time tension feedback and dynamic balance auto-correction technology. With MES system to realize the whole process data traceability. The program can achieve ±0.01mm assembly and positioning accuracy, reduce product defective rate to below 0.5%, 29 main processes with zero manual intervention, and increase production efficiency by more than 3 times compared with manual line, meanwhile, it supports rapid changeover of multi-specification micro-motor, ensures the consistency of motor performance, and meets the demand for scaled-up and high-precision production under low-altitude economy.
