Construction                                                                   

WINDING/INSULATION FORM WOUNDV.P.I. CLASS F SYSTEM

TECO utilises mica tape as its base material, which is impregnated with a special epoxy resin. Impregnation is accomplished by immersion of the completely assembled stator in the special resin using a vacuum pressure cycle. This ensures outstanding resistance to heat, moisture, and chemicals, and guarantees safe operation even under most severe environmental conditions.

STATOR FRAME CONSTRUCTION

Crown Series motors use box frame construction to provide frames that have the mechanical strength and stability to assure years of dependable, economical performance. The fabricated steel frames are braced by heavy steel plate bulkheads and end plates to make the frames both laterally and torsionally stable. End brackets are reinforced to give the bearings rigid support and to minimize bearing stiffness.

 

STATOR WINDING BRACING

Bracing rings of insulated steel or epoxy glass yarn are used. Individual coils are lashed to the ring with glass cord. Impregnated felt packers are used between coil sides. Support of the coil ends is designed to restrain shock and vibration of the coil ends under heavy overload conditions such as those which occur during full voltage starting

ROTOR MOTORS

TECO-Westinghouse induction motor rotors are recognised as the most reliable in the industry, and their high performance standards are a hallmark of the Crown Series motors. Standard construction utilises copper-copper/alloy bars, a time-proven choice for rotor construction because it provides maximum performance and reliability, and high quality silicon steel laminations to minimise losses resulting in high efficiency values. Connection between rotor bars and end rings are joined together using silver brazing and a “1 shot” brazing technique developed by TECO. Rotors balanced to ‘N’ grade as per BSEN and NEMA standards.
