How to repair the stator on the electric motor of electric forklift?

Electric forklift is a kind of forklift operated by electricity. It conforms to the global trend of advocating environmental protection and energy conservation, and is currently widely used in various places. Since the forklift is powered by electricity, the importance of electric motor to electric forklift is self-evident. The stator is a very important part of the electric motor. Once it fails, it will lead to poor operation of the electric motor. So, how can we judge what is wrong with the stator and how to repair it? Manufacturer which has forklift for sale comes to talk about this topic.

If the electric forklift is damaged or aged due to long service time, the stator winding may have inter-turn or inter-phase short circuit. If ground has a problem, the insulation of the stator winding may be damaged. So, how do we check whether the stator winding is faulty? First, check whether the external wire is broken and whether the wire end is soldered off. If there is no problem in the external inspection, check the internal condition. Use a 220V AC test lamp to check any end and iron core. If the test lamp is not on, it will prove that everything is normal. Otherwise, it will prove that there is a fault in the ground. If you want to further determine where the fault of the ground is, you can check it separately with star connection points. To check whether there is an open circuit, the manufacturer which has forklift for sale told us to use a multimeter to check whether the start and end of each winding are connected. If not, it will prove that there is an open circuit.

Check whether the stator of the electric motor of the electric forklift has a short circuit, and use a multimeter or AC test lamp. The specific operation method is to disconnect the star connection point first, and then connect the contact pin to the two outgoing lines. If the circuit is still open or the AC test light is on, it indicates that there is a short circuit problem. So how can we solve the problems of stator’s ground, short circuit and open circuit? The manufacturer which has forklift for sale told us that it can be welded in case of open circuit, and the slight short circuit need to be replaced or padded with insulation. If the short circuit is caused by the burning of the winding, the winding can be rewound or replaced directly.

The above is the way to check and repair the stator of the electric forklift’s electric motor. If there is a problem with the electric motor of your electric forklift, you can find out whether it is caused by the fault of the stator. Here, the manufacturer which has forklift for sale still suggests that if you still have a headache in the face of such complicated and tedious maintenance work, you should find professional personnel to solve it.
