SERIES Energy Efficient TEFC Induction Motors SERIES Induction Motors Crompton Greaves’ series belongs to a family of state-of-the-art energy efficient totally enclosed fan cooled (TEFC) 3 phase Induction motors with cage rotor construction. An almost flat efficiency curve is achieved by effectively utilizing materials (special grades of materials) while minimizing losses. In conjunction with thermally optimized frames, cooling fans are designed with low noise profiles. Higher efficiencies at part loads result in greater energy savings making it suitable for use when load variations exist. The components are optimized using finite element analysis of electromagnetic, structural, thermal and air flow, which ensures better stress distribution and high structural rigidity. Adequate steps have been taken in the electrical design process to make sure that the natural frequencies of stator teeth and core remain well away from the supply frequency. Appropriate selection of tolerances and fits in addition to good manufacturing processes facilitate high level of quality. The rotor and fans are separately balanced on precision balancing machine to very stringent grades. All these put together, result in extremely low vibration levels.
