In addition to having the function of bending pipe, the cylinder can also be used as a hydraulic jack, which has the characteristics of cheap price and convenient use. Numerical control can be used for winding bending of a bending radius (single mode) or two bending radius (double mode) in the cold state of the pipe, which is widely used in the bending of various pipe fittings and wires in automotive, air conditioning and other industries. benefits of automatic cnc pipe end forming machine. Benefits of automatic CNC pipe end forming machine.

Today we are going to explore the topic, what is the cause of the motor failure, and how to eliminate it?

1, the cause of motor failure

① When the motor is repaired, the number of turns in the stator winding is reduced too much;

② The power supply voltage is too high;

③Y connected to the motor the motor is mistakenly connected to Δ;

④benefits of automatic cnc pipe end forming machine Motor In motor assembly, the rotor is inverted, so that the stator core is not aligned, and the effective length is shortened;

⑤ The air gap is too large or uneven;

When overhauling and removing the old winding, the improper use of thermal dismantling method causes the core to burn.

2. benefits of automatic cnc pipe end forming machine Troubleshooting process

① Rewind the stator winding to restore the correct number of turns;

② Try to restore the rated voltage;

③benefits of automatic cnc pipe end forming machine The motor is changed to Y;

④ Reassembly;

Replace the new rotor or adjust the air gap;

⑥ Overhaul the iron core or recalculate the winding to increase the number of turns appropriately.
