TECHNICAL CHARACTERISTICS

		Motors are offered in Cast iron frame and end shields.

		Motors can be offered for multiple voltage 380V, 400V, 440V, 460V, 480V and Multi-frequency 50/60Hz,.

		The winding is Vacuum Pressure impregnated with F class insulating enamel to ensure high resistance to electrical, thermal and mechanical stress.

		The phases are further isolated by another layer of Nomex film to protect the motors from the voltage peaks that usually occur when the motor is controlled by an inverter.

		The motors are equipped with 2 nos pull resistant cable

		gland for main cables and 1 no for thermistor cable.

		The rotor is dynamically balanced according to IS:12075, IEC 34-14 and ISO 9921 norms.

		The terminal box can be rotated through 360° in steps of 90°.

		Superior Efficiency and Performance is achieved by the FeV magnetic lamination sheets adoption, instead of the usual normal FeP01. FeV lamination sheets provide higher efficiency, lower heating, energy saving and longer life to insulation materials.

		To protect against corrosion and rust, motors are painted with RAL 5007 blue colour.

		The motors are provided with bearing covers inside and outside on both drive end and non drive end for resistance to axial movements.

		Bearing lubrication devices are provided in motor frame 180 – 355 as a standard feature.

		Motor in frames 180 – 355 are embedded with a set of 3 nos thermistors as a standard feature for motor protection.
