Primary copper loss reduction: Coil
Optimizing the slot shape and increasing the wire occupancy reduces copper loss occurring in the stator coil.
Secondary copper loss reduction: Rotor
We have researched the loss caused by a harmonic current that flows through the aluminum conductor and reduced this loss by optimizing the slot shape.
Iron loss reduction: Iron core
The use of an iron plate made of high-grade materials that cause little loss results in a reduction in loss occurring in the iron core of the stator.
Stray load loss reduction: Harmonic analysis
We have conducted electromagnetic field analysis to research the loss that harmonics cause in the iron core
and reduced harmonic iron loss by optimizing the number of slots and the slot shape.
Mechanical loss reduction: Fan
A new type of fan has been developed that achieves a balance between cooling performance improvement and loss reduction.
Noise generation has also been reduced.
Cooling performance improvement: Frame
We have conducted 3D fluid and thermal analyses to research airflow distribution and radiation performance. A new frame has been developed that features improved cooling performance achieved by optimizing the frame shape.

Adopts
- Excellent energy-saving performance provides increased economic effects.
- Compatibility with the standard motors is ensured in terms of the installation dimensions.
- Class 155 (F) insulation (temperature rises limited to Class B) is used.
Excellent energy-saving performance provides increased economic effects.
The high efficiency premium series reduces loss that occurs in the motor. This reduces power consumption during motor operation, and a lower electric power cost provides an energy-saving effect.
