Description: 
Special Application Motors range include single phase (0.25 HP to 2 HP) and 3 phase (1/10 HP to 20 HP) electric motors. It is used for intermittent duty and hoist/crane duty; motors with electromagnetic disc brake, motors for heavy switching/reversing duties, torque-rated motors, for winders and prolonged stalling duty, textile & loom motors, motors for machine tools and motors for cooling towers. The mechanical features include motors with double shaft extensions, non-standard mounting dimensions, non-standard shaft extension, oil-tight shaft construction on drive end, higher degree of protection, IP54, IP55, reduced vibration levels and motors for corrosive atmospheres. The special electrical features supply voltage up to 550 V, dual voltage motors, wider operating voltages, supply frequency 60-25 Hz, wider frequency tolerance ±5%, lower synchronous speeds, like 500 & 375 RPM, 2 or 3 speed pole changing motors and motors with higher class of insulation.
