1
Use meter to check if the cable of motor is
short in circuit.
If yes, please replace the
motor.
If no, please progress the next
step.
2
Please contact the manufacturer for the
criterion of inductance, and measure the
inductance with LRC meter, and then check
if the value exceeds the criterion.
If yes, please replace the
motor.
If no, please progress the next
step.
3
Use scope to measure the EMF of motor and
check if the signal is correct or not.
