time2012/01/31

surgical headlight own reasons: connection error, the error connected to Y-shaped, so that surgical headlight temperature increased rapidly; surgical headlight with white short-circuit the stator winding inter-turn short circuit or local ground, light when the motor overheating, serious when the insulation burned; surgical headlight cage rotor broken bars or defects, surgical headlight run 1-2 hours, core temperature rose rapidly; surgical headlight ventilation system failure, the fan should be checked for damage, direction of rotation is correct, the ventilation channels is blocked; surgical headlight bearing wear, rotor eccentricity sweep chamber to rub the stator and rotor core issue with metal crash, the rapid rise in core temperature, severe motor smoke, even burn the coil.
