Reduced rare earth and magnet-free motors

The race is on to find ways of reducing the industry’s reliance on EV motor magnets made from rare earths. Peter Donaldson looks at the latest advances Rare earth (RE) magnets are essential components of the most efficient torque and power-dense motors used in EVs. However, factors including price, sustainability and
