The gear reducer motor may not be charged after a long time of use, so do you know what are the reasons for the gear reducer motor not charging?





1. The wire joints are loose or fall off, and the wire sheath is damaged and grounded to cause a short circuit.
2. The fan pulley is too loose or slips with oil.
3. The commutator of the motor is worn, burnt or oily, the armature coil is open or short-circuited, the commutator is short-circuited, and the insulating carbon brush holder is grounded.
4. The contacts of the regulator or restrictor of the gear reducer are ablated or dirty, the balance resistor is broken, the bridge line of the voltage regulator is burnt, the spring tension of the voltage regulator is weak, and the air gap is too small.

The grease used for the gear reducer is unreasonable, the quality of the grease is not good, and it is easy to produce poor heat dissipation. In this case, try to choose a regular and corresponding specification of grease and add it frequently.


The main reasons why the gear reducer motor is not charging are the above-mentioned ones. The main reasons why the gear reducer motor is not charging are the above-mentioned ones. When such a problem occurs, we all need to solve it in time.
