💡 Industry Background Supplement
These motors are core, easily damaged components in SMT equipment, operating continuously at high temperatures of 150-300℃. The main failure modes include:
Bearing jamming/abnormal noise (due to high-temperature grease failure)
Winding burnout (overheating/voltage instability)
Rosin/flux residue causing impeller imbalance
Shaft wear/breakage (due to prolonged high temperatures and high speeds)
