over-heat motor |
1.the temperature of environment is too high.
2.airiness is bad.
3.pressure is too high or too
low. |
1.take measure to reduce the temperature .
2.clean out the wind passage,
and check the motor if cooling
fan has been damaged.
3.adjust electrical source
pressure. |
the motor
can't work |
|
electrical source haven't been switched on |
check if the switch is contacted well ,if the fuse wise is broken or the motor down-lead is broken. |
the rotate
speed of the
output shaft
is too low |
|
wrong control connection outside
over loading
wrong ratio
electrical source pressure too
low
over-load |
correct it on the right connection
reduce the load
check the rotation ratio of the cooling fan and output shaft by hand
adjust electrical source pressure
reduce load |
