Variable flux permanent magnet machines represent a dynamic class of electrical machines in which the air-gap magnetic flux can be actively adjusted during operation. This flexibility permits improved ...

MUNICH, Germany—ZF unveiled an electric motor that does not require magnets or rare earth materials, reducing reliance on mining in countries such as China and cutting manufacturing's carbon footprint ...

This advanced variant of a separately excited synchronous motor is thus an alternative to permanent-magnet synchronous machines (PSM). New Delhi: ZF has developed an electric motor which does not ...

I2SM does not require any brush elements or slip rings. ZF has developed a magnet-free electric motor disparate to Separately excited synchronous motors. The motor is compact with maximum power and ...
