Description

Technical Field

[0001] The utility model belongs to the technical field of generator AC winding end covers, and in particular relates to an insulation structure of a cast iron generator AC winding end cover. Background Art

[0002] The cast iron generator AC winding end cover, commonly known as the "end cover," is a rear cover installed behind the motor casing. Its primary function is to determine the spatial position of the rotor shaft. By aligning with various bearing types, it connects to the motor stator housing to maintain clearance between the rotor and stator. Cast iron generator AC winding end covers are typically made of cast iron, a material with excellent mechanical properties and corrosion resistance, capable of withstanding vibrations and temperature fluctuations during motor operation. The design and manufacture of these end covers require quality assurance to ensure the performance and safe operation of the motor.

[0003] After the existing cast iron generator AC winding end cover is assembled with the generator, its rotor core will be embedded in the core slot inside the end cover. Since there is no insulating protection structure inside the core slot, the rotor core cannot be protected during use, and short circuit and current leakage cannot be avoided. For this reason, we propose an insulation structure for the cast iron generator AC winding end cover. Utility Model Content
