High Efficiency Design
TECO-Westinghouse Motor Company synchronous machines feature high efficiency designs in which great care is taken to minimize losses. Various design features are manually selected to ensure maximum operating efficiencies and trouble-free operations:
- Airgap, slot openings and slot ratios are selected to reduce pole face losses due to flux pulsations.
- Low loss, core-plated, non-aging silicon steel stator punching of various dimensions are selected to reduce core losses.
- The stator copper is stranded to minimize eddy current losses.
- The number of stator slots, slot width, slot depth and stator core depth are dimensioned to reduce magnetic noise.
- Pole punchings are designed for reduced pole leakage flux and field excitation to reduce field copper losses.
- Blowers are carefully selected to reduce windage loss and provide maximum cooling. This helps reduce the overall machine size.
- Stator end-plates are designed to ensure a tight and rigid core assembly, to minimize noise due to core distortion and to transmit torque to the frame bulkhead.
