Companies Develop Rare Earth Magnet Alternatives Amid Crisis

Companies Develop Rare Earth Magnet Alternatives Amid Crisis
Battling rare earth magnet crisis · financialexpress.com

Some companies are making new types of motors without using special magnets called rare earths.

These magnets are important for many things like cars and phones.

China controls much of the supply of these magnets, which has caused problems.

Companies like Chara Technologies, Conifer, and Viridian Ingni Propulsion are making motors using different materials or designs.

These new motors use things like ferrite magnets or no magnets at all.

These alternatives could make it easier to get the parts needed, and some are cheaper and better for the environment.

India, with its growing electric vehicle market, is a good place to try out these new ideas.

Key facts

Chara Technologies
Uses synchronous reluctance machines (SynRMs) - rare-earth free
Conifer
Uses ferrite axial flux modular motors; reduces EV weight by 50% in industrial applications
Viridian Ingni Propulsion
Uses a hybrid approach with reluctance-based torque and ferrite magnet assistance
Neodymium Magnet Cost
Around Rs 5,000 per kg
Ferrite Magnet Cost
Around Rs 600 per kg
