These motors are designed for quieter operation even under abnormal load conditions. These frames are treated for high corrosion resistance. Higher degrees of protection (e. The advanced insulation the 'M2000' series gives high electrical and mechanical stability.The 'M2000' Series M2000 Motors have been engineered for the twin objective of high power to weight ratio and efficiency at a designed ambient of 500C. the stator is impregnated with a solventless resin.e. 'M2BA' Motors have a wide range of applications including windmill. Special attention is given to mechanical features of 'M2BA' for reliable operation at extremes of speed range in variable speed applications. All windings are tropicalised with epoxy gelcoat and made Insensitive to moisture and micro-organisms. 50 50 50 User friendly design 'M2BA' Motors have a user friendly design and less number of components leading to faster and trouble-free dismantling and assembly. 'M2BA' Motors are provided with regreasing facility. Winding Stator winding uses high quality enamelled wires conforming to IS:13730.e. IP55 'M2BA' Motors are protected against the ingress of water and dust. . 'M2BA' Motors have withstood the test of time and are established for reliability in stringent operating conditions like thermal power plants world wide. airborne and structural noise. Gaps between individual conductors are effectively filled with this material resulting in good thermal conductivity and superior mechanical strength. Voltage ranges for extra versatility The motors are matched to the standard voltages applicable in India i. A high degree of protection IP 55 is a standard feature of 'M2BA' Motors.

Effective and robust corrosion protection means that the motor can be used in all environments. Bearings 'M2BA' Motors use appropriately selected ball bearings with high temperature grease to give increased life and reliability. Ventilation EFFICIENCY % h 100 Typical efficiency of 4-pole motors. Special design of fan blades and segmental groupings of fins in horizontal and vertical planes offer the most efficient air flow and minimum air borne noise while incurring least windage losses. The terminal box can be rotated so that cables can be connected from the right or the left. Further. This provides a generous thermal overload margin bringing greater reliability and improves life of the motor. 'M2BA' Motors are the result of special efforts made to minimize electromagnetic. This can be used for such conditions as increased load. For high radial loads and belt driven applications roller bearings are provided. same housing length can be used for varied mounting applications. Enclosure 'M2BA' Motors use rigid cast iron / fabricated housings and are provided with integrated deeper longitudinal ribs designed to give maximum cooling surface area.
