What are the precautions for the maintenance of PCB splitter?

1. Causes of operation problems of PCB splitter

The battery does not have sufficient power, the connection between the battery and the starting motor is disconnected, and the battery or wiring clip is oxidized; Poor contact between the electromagnetic switch and the two terminals or serious ablation of the deflector; The electric brush is worn, broken or stuck in the brush holder; There is oil stain between brushes and rectifiers or serious ablation of rectifiers.

2. Partial short circuit or open circuit of winding

There are three reasons for this situation: one is that the armature winding or commutator piece is desoldered; the other is that the bearing or copper sleeve is worn, resulting in rotor chamber sweeping; the third is that the position of the four brushes is installed incorrectly during installation or the clearance of the newly replaced shaft sleeve is too large, and the time-space rotation of the PCB splitter is started: the shift fork is installed incorrectly, and the shift fork sliding column device makes it impossible for the motor gear to rotate with the shift fork in the moving bushing.

3. When the PCB splitter starts, the motor will rotate

The clearance between the iron core of the electromagnetic switch and the push rod of the connecting plate is too large, which causes the one-way clutch to slip and cannot drive the flywheel ring gear to rotate. Once the gear of the starting motor is seriously worn, it will not be able to run in well with the flywheel ring gear.

The electromagnetic switch is always on and always on, which means that after pressing the start switch, the iron core of the electromagnetic switch will be taken off immediately as soon as it is sucked up, and then it will be sucked up again, and then it will be taken off immediately, which can not achieve the effect of starting the initiator.
