As a high-speed, high-power density component, the assembly accuracy of the stator and rotor of the model aircraft brushless motor directly affects the motor efficiency, temperature rise and life. Below, Vacuz will explain from three aspects: process flow, key equipment, and key points of operation. I hope it can help everyone!

1. Assembly process flow

The assembly of model aircraft brushless motors is divided into four stages: stator pretreatment, rotor pretreatment, stator and rotor assembly, and final inspection. Technical requirements include key parameters such as winding insulation resistance, paint dripping coverage, notch chamfering, magnetic steel bonding strength, dynamic balancing grade, bearing clearance, concentricity, air gap control, and locking torque.

2. Core equipment and functions

‌1. Stator processing equipment‌: winding machine, paint dripping machine, notch chamfering machine.

‌2. Rotor processing equipment‌: magnetic steel bonding tooling, dynamic balancing machine, bearing press machine.

‌3. Stator and rotor assembly equipment‌: concentricity calibration table, air gap measuring instrument, locking torque controller.

3. Key points of operation and guide to avoid pitfalls

‌1. Error prevention of stator winding: wire diameter matching, anti-jump wire skills, number of turns verification.

2. Anti-detachment of rotor magnetic steel bonding: surface treatment, curing monitoring, bonding strength test.

‌3. Anti-scratch of stator and rotor assembly: air gap control, concentricity calibration, dust prevention measures.

4. Efficiency improvement plan

‌1. Automation upgrade: introduction of six-axis robot and CCD vision system.

‌2. Process optimization: use of “flying fork winding + synchronous wiring” technology and composite dynamic balancing process.

‌3. Data traceability: automatic upload of assembly parameters to MES system.

The above points cover the full range of assembly of stator and rotor of brushless motor of model aircraft, which is of great significance to ensure the assembly accuracy and performance of motor. I hope these little knowledge can help you!
