TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
SOLUTION
MOTOR WILL NOT
START
Usually caused by line trouble, such
as single phasing at the starter
Check source of power. Check overloads,
fuses, controls, etc.
MOTOR OVERHEATING
Overload. Compare actual amps
(measured) with nameplate rating
Locate and remove source of excessive
friction in motor or load.
Reduce load or replace with motor of greater
capacity.
Single phasing
Check current at all phases (should be
approximately equal) to isolate and correct
problem.
Improper ventilation
Check external cooling fan to be sure air is
moving properly across cooling fins.
Excessive dirt build-up on motor. Clean motor.
Unbalanced voltage
Check voltage at all phases (should be
approximately equal) to isolate and correct the
problem.
Over voltage or under voltage
Check input voltage at each phase to motor.
Open stator winding
Check stator resistance at all three phases for
balance.
Improper connections
Inspect all electrical connections for proper
termination, clearance, mechanical strength
and electrical continuity. Refer to wiring
diagrams.
BEARING
OVERHEATING
Misalignment
Check and align motor and driven equipment.
Excessive belt tension
Reduce belt tension to proper point for load.
Excessive grease in bearing
Remove grease until cavity is approximately
3/4 filled.
Insufficient grease in bearing
Add grease until cavity is approximately 3/4
filled.
Dirt in bearing
Clean bearing cavity and bearing. Repack with
correct grease until cavity is approximately 3/4
filled.
GROWLING OR
WHINING
Bad bearing
Replace bearing. Clean all grease from cavity
and new bearing. Repack with correct grease
until cavity is approximately 3/4 filled.
