ROUBLESHOOTING

1. Read the nameplate to become familiar with the motor, especially the rated voltage.

2. Try to turn the shaft by hand. Keep motor leads separated while doing this. If the shaft turns 

freely, go to step 3. If the shaft won’t turn, proceed to step A.

a. The shaft could be tight for a number of reasons, this check is to determine if 

the tightness is of a temporary nature only. Obtain power to produce the 
nameplate voltage. Do not make a permanent connection. First touch the 
motor leads quickly to the power supply just long enough to observe if the 
shaft runs. If it does turn, then hold the motor leads on the power supply for a 
longer time.If the motor sounds normal, go to step 3. If the motor sounds 
noisy, it should be taken apart as described in the disassembly section.

3. If the motor turned freely, connect an ammeter in the circuit as shown in Figure 3-9A. With 

rated voltage applied and the shaft running free, the ammeter should read less than 20% of 
the nameplate full load current. If the motor meets the above conditions, then it can be 
assumed the original problem is external to the motor.

ISASSEMBLY

NOTE:

 Do not place the stator ring in any mechanical 

holding device during the disassembly or assembly 
operation. Permanent distortion or other damage will 
result.

1. Remove three bolts.

2. Remove pulley end cover.

3. Pull the armature out of the assembly in one 

swift motion.

4. Remove commutator end cover.

I

NSPECTION

1. Once the motor has been disassembled, go 

through the following check list steps to deter-
mine where the problem lies.

2. Bearings should spin smoothly and easily and 

have ample lubrication and be free of corrosion.

3. Armature should be checked for grounds and 

shorted turns. Refinish commutator surface if 
pitted or excessively worn.

4. Brushes should be checked for wear and to 

ensure that they are free in the brush holders.
