What are the reasons for the failure of the walking motor of the electric storage pallet truck?

When the storage pallet truck is in use, special attention should be paid to the operation of the walking motor. In the following cases, it should be eliminated in time according to the cause of the failure of the electric storage pallet truck: The storage pallet truck cannot be started. It may be caused by blown fuse, blocked control circuit, serious short circuit or open circuit of motor winding, short circuit between commutator segments, poor contact of brushes, heavy load or mechanical damage such as bearings.

1. The speed of the electric storage pallet truck is not correct.

It is often possible that the winding of the storage pallet truck is short-circuited or open, the brush position is incorrect and the storage The pallet truck is overloaded, the bearing is damaged, and the power supply voltage is too low.

2. Sparks occur in the brushes of the electric storage pallet trucks

It may be that the brushes of the storage pallet trucks are in poor contact, the surface of the commutator is uneven, the position of the brushes is not correct, The surface is dirty, the commutator is short-circuited, or the motor winding of the storage and handling pallet truck is short-circuited.

3. The electric storage pallet truck generates high temperature

It may be due to the overload of the electric storage pallet truck, the bearing and oil seal are too tight, damaged or poorly lubricated, the shaft core is not correct, the armature and Magnetic pole phase friction, winding short circuit, excessive brush pressure, incorrect position, poor rectification and other reasons.

4. The electric storage pallet truck has noise

The main reasons are the bearing damage of the electric storage pallet truck, the uneven surface of the commutator, the vibration or friction of the brush and so on.
