5 HP Totally Enclosed Fan Cooled Electric Motor
V 4.1
Problem(s)
Possible Cause(s)
Suggested Solution(s)
Fuse/circuit
breaker
overloads.
1. There is a blown fuse or open
circuit breaker.
2. Motor starter overload
activated.
3. Low or no voltage reaching
motor.
4. Power enters control circuit
but does not reach the
motor.
5. Motor shaft does not turn
when power applied.
1. Test for voltage at the fuse or circuit
breaker. Also see if the voltage/amp
rating of the fuse or circuit breaker
is correct for the motor. It should
exceed the Motor’s FLC by 25
percent.
2. Let cool and then reset overloads.
Test the starter before starting
motor again.
3. Check each motor terminal’s
voltage. The voltage should be
within 10% of the voltage on the
motor’s nameplate. Disconnect the
load and apply power to the motor.
If the motor operates normally, then
the issue is with the load attached to
the motor. Should the motor still not
work, have it serviced or replaced by
a qualified technician.
4. Begin by confirming all contacts are
clean and tight. Examine for obvious
damage.
a. Test each part of the circuit for
power until the problem area is
discovered.
b. Have a qualified service
technician repair or replace the
circuit.
5. Disconnect the motor from the load
and test under no-load conditions. If
the shaft does not turn, the bearing
are immobilized. Have the motor
serviced or replaced by a qualified
technician.
