New Generation 2020 Duplex Cooling series with Unique Motor Design….

Introduction

Having Duplex Cooling system where the temperature of winding is evenly distributed throughout the overall surface of stator and rotor cores and their windings.

The rotor is aluminium pressure die casted with number of ventilated cooling slots from which the internal cooling air flows and this hot air is transferred through the number of channels provided in the stator housing with the help of aerodynamically shaped internal cooling fan which is mounted on rotor shaft. This results in higher efficiency due to the lower losses.

Bearing system is designed for better life and greater reliability.

Winding wires are having dual coated enamel covering having temperature index of 200°C & vacuum pressure impregnation (VPI) ensures superior electrical insulation system.

Robust housing design is capable to sustain extremely high loading stresses.
