MOTOR TROUBLE SHOOTING CHART

 

TROUBLE 

CAUSE 

WHAT TO DO 

Motor fails to start  Blown fuses 

Replace fuses with proper type and rating. 

Overload trips 

Check and rest overload in starter. 

Improper power supply 

Check to see that power supplied agrees 
with motor nameplate and load factor. 

Open circuit in winding or control 
switch 

Indicated by humming sound when switch is 
closed. 

Mechanical failure 

Check to see if 
motor and drive 
turn freely. Check 
bearing and 
lubrication. 

Short circuited stator 

Indicated by blown fuses. Motor must be 
rewound. 

Poor stator coil connection 

Remove end bells, locate with test lamp. 

Rotor defective 

Look for broken bars or end ring. 

Motor may be overloaded 

Reduce load. 

Motor Stalls 

One phase connection 

Check lines for open phase. 

Wrong application 

Change type or size. Consult manufacturer. 

Overload motor 

Reduce load. 

Low motor voltage 

See that nameplate 
voltage is 
maintained. Check 
connection. 

Open circuit 

Fuses blown, check overload relay, stator 
and push buttons. 

Motor runs and 
then dies down 

Power failure 

Check for loose connections to line, to fuses 
and to control. 

Motor does not 
come up to speed 

Not applied properly 

Consult supplier for proper type. 

Voltage too low at motor terminals 
because of line drop. 

Use higher voltage on transformer 
terminals or reduce load. Check 
connections. Check conductors for 
proper size. 

Broken rotor bars or loose rotor. 

Look for cracks near the rings. A new 
rotor may be required as repairs are 
usually temporary. 

Motor takes too 
long to accelerate 

Open primary circuit 

Locate fault with testing device and repair. 

Excess loading 

Reduce load. 

Poor circuit 

Check for high resistance. 

Defective squirrel cage rotor 

Replace with new rotor. 

Applied voltage too low 

Get power company to increase power tap. 

Wrong rotation 

Wrong sequence of phases 

Reverse connections at motor or at 
switchboard. 

Motor overheats 
while running under 
load 

Overloaded 

Reduce load. 

Frame or bracket vents may be 
clogged with dirt and prevent 
proper ventilation of motor. 

Open vent holes and check for a continuous 
stream of air from the motor.
