CONSTRUCTIONS: The stator Housing and end shields are made from grey iron castings. The Stator housing has been provided with a greater number of parallel ribs to ensure ruggedness & better heat dissepation.
CORE: The core is made from low loss, high permeability, varnish insulated electrical grade sheet steel which is compressed, keyed & then clamped to from a rigid structure. This cleated stator stacks, pre wound & hydraulically pressed in cast iron frame, ensure better stacking, uniform air gap & correct fits.
WINDINGS: The Stator is generally wound with enameled copper wire with class F insulation connections normally prevaleant in soldering.
ROTORS: The Rotor is of squirrel cage type, designed to withstand the save forces encountered during starting. Rotors are specially die-cast skewed for better performance, Each Rotor is dynamically balanced to ensure very low amplitude vibration & low noise level.
TREATMENT: Wound stators are impregnated using polyster resin varnish having class ‘F’ Thermal stability.
SHAFT: Shafts are made from high carbon steel at adequate cross sections to provide exceptional strength and rigidity to minimize deflection & vibration.
TERMINAL BOX: The rigid by scaled terminal box is arranged on the right hand side of the farm when viewed from the driving end.
BEARINGS: Grease lubricated ball bearings are housed in end shields. These bearings have a 90% survival life of a minimum 30,000 working hour for direct drives.
TEST: Motors are subscribed to routine & type testes in accordance with latest standards.
