Mitsubishi Electric High-performance energy-saving motor + Superline premium series + SF-PR type

The rotor has a slot shape that takes into consideration the characteristics during instruction while suppressing resistance during operation.
Furthermore, the number of slots has been optimized.
The shape of the cooling fan is optimized considering the balance between cooling performance and mechanical loss.
The iron core uses a material with low generated loss, and the flow of magnetic flux is reviewed to optimize the shape.
For electric wires, resistance is suppressed by increasing the cross-sectional area of the electric wire by improving the electric wire space factor and shortening the crossover.
The frame is made of steel plate that easily allows magnetic flux to pass through and is suitable for high-efficiency design.
* Regarding domestic high efficiency regulation compliance
It complies with Japan's Top Runner regulations at 200/200 / 220V 50/60 / 60Hz and 400/400 / 440V 50/60 / 60Hz.
Since there is no certification system for domestic top runner regulations, there is no certification number.
* Regarding compliance with US high efficiency regulations
It complies with US EISA law at 230V60Hz and 460V60Hz.
The conformity certification number CC012A is displayed on the main body name plate.
It does not support UL standards.
* Since the mounting dimensions (frame number) are compatible with the SF-JR type, replacement can be done smoothly.
