💡 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)
