Winding failure and maintenance method of reducer electromechanical machine

Winding failure and maintenance method of reducer electromechanical machine:

Winding is an important part of the motor. Winding aging, moisture, heat, erosion, foreign body invasion, external impact will cause different degrees of damage; Motor overload, undervoltage, overvoltage, lack of phase operation will also cause winding failure. There are four common windings fault, generally divided into winding grounding, short circuit, open circuit, wiring error. Below tin blue reducer to explain the winding grounding fault phenomenon, causes and inspection methods. Winding grounding refers to the grounding caused by the damage of winding and iron core or insulation with the casing.

1. Fault phenomenon: the shell is charged, the control circuit is out of control, and the winding is short-circuited and heated, so that the motor can not run normally.

2, causes: winding damp insulation resistance drop; Motor long-term overload operation; Harmful gas corrosion; Metal foreign matter intrudes inside winding and damages insulation; When rewinding stator windings, insulation damage to iron core; Winding end touch cover frame; Insulation burns caused by friction between stator and rotor; Lead wire insulation damage and shell collision; Over voltage (e.g. lightning strike) causes insulation breakdown.
