Stark motors presents a wide range of three phase motors engineered for commercial and industrial applications. The motors are made as per relevant bis standards [is 325] and carefully tested before despatch. The rugged components are created of cast iron pertaining to is 210 standards and the stator frames with deep fin construction assures adequate cooling surface. The motors are offered in the range of 0.18 kw [0.25 hp] to 11.0 kw [15 hp] at a speed of 1000-3000 rpm. Wound stators are pre-heated to drive off moisture and then pass through a multiple dip and bake cycle that impregnates and coats the windings with high temperature insulating varnish. A final dip in red epoxy insulating enamel provides a protective overcoat. Technical specification: insulation - class e or b; supply - 415 v, 50 hz; standard cooling - totally enclosed fan; enclosure - ip 44 [ip 54 or ip55 on request]; double side shielded bearing up to 100 frame; and pre-packed lubricants.
