Problem -
Motor/Reducer
Possible Cause Remedy
1.
Motor will not start
No line voltage
Check emergency stops and reset.
Check fuses and wiring for open circuit. Check thermal
overload protection device. Check limit switches, starter
and relays for faulty contacts or mechanical fault. Check
voltage at source.
Check control circuit voltage.
Low line voltage Check for low resistance short on line.
Conveyor overloaded or jammed
Check for foreign material in chain and sprockets.
Check for material between belt and pulleys.
Check conveyor belt tension.
Remove product overloading from conveyor and
address cause.
Check chain tension.
Burned out motor
Replace motor with spare and send defective motor to
authorized repair station.
Failure of electrical component
Check photoelectric control relay, timing modules and
start/stop pushbuttons.
2.
Motor running
excessively hot
Note:
Temperature up to
175º (hot to touch) is
normal.
Drag on conveyor
Inspect entire conveyor for obstruction or falling
bearings.
Lack of reducer lubricant
Check oil level in gear case. Be sure breather plug is
open (if used).
Too much lubrication Drain off excess.
Frozen pulley or roller
Check all pulleys and bearings for free rotation. Replace
if frozen or difficult to rotate.
Wrong grade oil Drain and refill with proper grade.
Electrical
Check wiring and circuits. Take ampere reading and
compare with motor rating on name plate.
Key ramped up on the motor shaft,
causing excessive bearing load.
Remove motor to reducer mounting belts. Pull motor
back and reposition key, push motor back onto reducer.
Binding or excessive resistance should not be felt.
Overloaded conveyor Remove excess product. Address cause.
Misthreading belt path
Reroute belt path correctly.
3.
Reducer runs – drive
pulley does not turn Drive chain broken or
disconnected
Replace chain or repair.
