– Overloading is strictly prohibited.
– It is strictly prohibited to coexist with strong magnetic objects.
– The input voltage level needs to be ensured to be correct.
– If any abnormal odor is found during use, the motor should be immediately stopped for
inspection.
– The wiring between the motor and controller should be as short as possible.
– If the motor experiences leakage, sudden decrease in speed, severe vibration, abnormal
noise, overheating, smoke, or electrical appliances during operation
– If the contact ignites and emits smoke, it should be immediately powered off and shut down
for inspection.
Use and maintenance
Before leaving the factory, all components of the stator have been adjusted, and the neutral
position of the carbon brush has been adjusted on the factory test bench. Users are not allowed
to disassemble or adjust it arbitrarily
– Check if the armature rotates flexibly and if there is any virtual friction.
– Check if the connection of the motor outlet (or terminal) is correct and secure.
– The electric carbon brush should slide freely inside the carbon brush holder box.
– Check if the commutator space is clean, and if necessary, clean the small grooves between
the commutator space and the carbon powder on the commutator surface, which can be soft
and free.
A clean white cloth with fluffy threads. If there is grease on the surface, the white cloth can be
soaked in alcohol when wiping (parking).
– Check all fasteners for tightness.
– The carbon brush holder must be securely fastened and not loose. If it is necessary to rotate
or disassemble the carbon brush holder, markings must be made in order to loosen the end
cover screws and carbon brush holder when resetting, align the marked line and tighten the
screws to keep the carbon brush in its original neutral position.
– The insulation resistance of the coil should be regularly checked, and when it is close to the
working temperature, it should not be lower than the data specified, otherwise it should be
dried.
Regularly open the motor end cover and check if the internal parts are deformed and if the
commutation part is normal.
– Frequently carbon brush off the sediment and other adhesive substances on the casing to
avoid affecting its heat dissipation.
– Check the motor at least once every six months according to the following methods:
a. External inspection and removal of dust from the motor;
b. Clean or replace the bearings, and carefully listen for any abnormal noises from the bearings
during operation;
c. Check the wear of the electric carbon brush and replace it if necessary.
