1. Causes of motor failure of pipe bending machine
1 When the bender motor is repaired, the stator winding turns are reduced too much;
2 power supply voltage is too high;
3Y connection bender motor motor is incorrectly connected to Δ;
4 In the assembly of the motor of the bender motor, the rotor is reversed, so that the stator core is not aligned, and the effective length is shortened;
5 air gap is too large or uneven;
6 When the old winding is removed, the hot-disassembled method is used improperly to burn the iron core.
1 rewind the stator winding to restore the correct number of turns;
2 try to restore the rated voltage;
3 bender motor is changed to Y;
5 Replace the new rotor or adjust the air gap;
6 Overhaul the core or recalculate the windings and increase the number of turns as appropriate. The Jiejie mechanical pipe bending equipment adopts the domestic advanced Far East motor. The safety and reliability failure rate is extremely low.
