STATOR WINDING BRACINGWINDING/INSULATION – FORM WOUND V.P.I. CLASS ‘F’ SYSTEM
The insulation system determines the ‘life’ of a motor. Motor capacity is influenced by the quality of insulation. TECO-Westinghouse utilizes 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 the most severe environmental conditions. The Crown Series windings are considered sealed and capable of passing a complete water immersion test. 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.

TERMINAL BOXES
Crown Series motors feature main lead terminal boxes constructed of 12-guage steel, gasketed for air-tight, dust-free and weatherproof protection of terminal leads. Available options include lightning arresters, surge capacitors, current transformers, special grounding devices, cable or bus bar terminations, and top or bottom lead entry.

ADVANCED BEARING SYSTEM FOR RELIABLE PERFORMANCE
The bearing system used in Crown Series motors has been designed and engineered in cooperation with Renk for continuous, reliable performance and easy maintenance. Both anti-friction and split-sleeve bearings are offered. Our split-sleeve bearings are spherically seated and self aligning, thus easy to service in all field conditions.

AVAILABLE ENCLOSURES
Crown Series motors are offered in a complete range of NEMA and IEC enclosures to meet the toughest demands of industry.

  • Open Drip Proof (ODP)
  • Weather Protected Type II (WPII)
  • Totally Enclosed Water-To-Air Cooled (TEWAC)

  • Pipe/Force Ventilated (TEFV)100% ROUTINE TEST

QUALITY & TESTING
Quality is emphasized at each step as a motor proceeds through each stage of design, assembly and testing. Each motor is given a routine test as required by IEC 60034 or NEMA MG 1 to determine that it is free from electrical or mechanical defects. Additional special tests beyond the routine test are available on request. Tests may be witnessed if required.
