Conveyor Motor Overtemperature

Motor thermal protection tripped. Motor is too hot to operate safely.

Probable Causes (ranked)

• Overloaded conveyor — too much product weight
• Motor cooling fan failed or air intake blocked by debris
• Ambient temperature too high — poor ventilation in area
• Motor bearing failing — increased friction generating heat
• VFD running motor below nameplate speed without external cooling

Fix Steps

1. 1 Let motor cool before restarting — minimum 15 minutes
2. 2 Check motor fan — spin by hand, verify it turns with motor
3. 3 Clear any debris blocking motor air intake and cooling fins
4. 4 Feel motor bearings (carefully) — excessive heat or noise indicates failure
5. 5 Check conveyor loading — reduce product if overloaded
6. 6 If motor runs at reduced speed via VFD, add external cooling fan
7. 7 Check motor current draw vs nameplate — sustained over FLA indicates problem
