How do you handle issues of scalability in both low-frequency and high- A good example is the traction drive. frequency scenarios? Engineers have been looking at the use of synchronous reluctance motors to From Industry 4.0 automotive andsignificantly reduce manufacturing costs aerospace manufacturing to heavyby removing the expensive permanent equipment, innovative electric motormagnets (often neodymium magnets). design and development have becomeThis can lead to a significant loss of industry make or breaks.
