ELECTRIC MOTOR INDUSTRY SOLUTION
Advanced Solution for the Electric Motor Chain
As the core equipment for converting electrical and mechanical energy, motors are widely used in fields such as new energy vehicles, industrial automation, household appliances, aerospace, etc. As a pioneer in joining solutions, Heron solves critical electric motor welding challenges in stators, rotor shafts, connecting terminals, motor housing, and motor parts, etc.
INDUSTRY PAIN POINTS
Three Overarching Joining Challenges
After 50+ electric motor manufacturer visits, we found that regardless of motor type — NEV drive motors or industrial servos — the pain converges on three systemic problems every manufacturer is wrestling with.
01
Risks in Enamelled Wire & Terminal Joints
Joining enamelled wires to terminals risks burning the insulation layer, causing inter-turn short circuits and sudden motor failure under high thermal loads.
02
Heat-Affected Zone Control Challenges
Traditional welding high temperature (>800℃) destroys magnet wire insulation. Meanwhile, flat wire motor enamel thickness is only 20-30μm, extremely sensitive to heat input.
03
Extremely High Welding Precision Requirements
Large copper rotors’ weld conductivity requirements are strict, prone to incomplete penetration and cold cracks. While some motor housing wall thickness is only 2-3mm, easily deformed with ordinary welding.
OUR SOLUTIONS
Joining technology for every electric motor welding part
30 years of joining expertise distilled into four systemic capabilities — from stable current control to data closure, running through every machine and line we deliver for electric motor industry.
