The rotor is a slot shape that takes into account the characteristics of instruction while suppressing the resistance during operation. Furthermore, the number of slots is optimize d. The cooling fan optimizes the balance between cooling performance and mechanical loss. The iron spirit uses a small material of the generated loss, and optimizes the flow of the magnetic flux to optimize the shape. The electric wire suppresses resistance due to an increase in the wire cross -sectional area due to an improvement of the electric wire accumulation ratio and a shortening of the migration. The frame is made of steel plate suitable for high -efficiency design that is easy to pass through magnetic flux. Show more
