AI Technical Summary
Existing circular radial flux motors suffer from problems such as large axial dimensions, low power density, low efficiency, and high power consumption in the field of robotics, making it difficult to meet the high-power operation requirements of large welding robots and heavy-duty palletizing robots.
A dual-stator single-rotor axial flux motor structure is designed, which adopts the flat wire winding α winding method, rotor bracket slotting and potting combined with carbon fiber fixation, and controls the air gap uniformity by adjusting the shims. The stator and rotor layout is optimized to reduce eddy current loss and leakage flux, and improve the slot fill factor.
It achieves a significant reduction in motor axial dimension, an increase in power density, a 10%-15% increase in motor efficiency, enhanced magnet fixation, improved operational stability and reliability, and adapts to the compact layout and energy-efficient requirements of robots.
