Most electric car engines have magnets, which are often made of rare earth metals like neodymium. Because powered coils require electricity to be transferred from the battery to the coils in a spinning rotor, it’s great to have a persistent source of powerful rare earth magnetism in your rotor.
Vehicle manufacturers are aware of these concerns, and many have stated that rare-earths will be eliminated or reduced in their electric motors.
Although the amount of REE used in a product may not constitute a substantial portion of the product in terms of weight, value, or volume, REE may be required for the device to function.
The electric motors utilised in EVs have a rare-earth motorway off-ramp.
Several concerns, such as the scarcity of fossil fuels, price volatility, greenhouse gas emissions, and present levels of pollution in urban areas, are driving the development of greener transportation systems based on more efficient electric and hybrid vehicles.
The electronics, defence, and renewable energy industries all rely on rare earths. The magnets they manufacture are known as permanent magnets because they can generate a steady magnetic pull.
These use less battery power than conventional magnets, allowing vehicles to travel longer distances before recharging.
The Global Rare Earth Free Electric Motor Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2027, registering a CAGR of XX% from 2022 to 2027.
MAHLE is working on a new type of magnet-free electric motor that doesn’t use rare earth elements. This not only makes production more ecologically friendly, but it also saves money and ensures resource security. The inductive, and hence contactless, power transmission is a key characteristic of the new motor, allowing it to function wear-free and efficiently at high speeds.
The new MAHLE traction motor is extremely efficient—at practically all operating points—and displays these benefits in categories where cars are mostly used in real-world traffic.
Mahle is working on a new magnet-free electric motor for electric vehicles. This electric motor is said to not require rare earth metals, which are difficult to come by and expensive. The motor is inductive and features a contactless power transmission, according to Mahle.
Our innovative traction motor does not use rare earth magnets, but instead uses an excitation coil in the rotor to generate the necessary magnetic field for operation.
Toyota Motor Corporation has created the world’s first heat-resistant, neodymium-reduced magnet. Neodymium magnets are utilised in a variety of motors, including high-output motors found in electric vehicles, and their use is likely to skyrocket in the near future. The new magnet requires a lot less neodymium, a rare-earth element, and it can withstand high temperatures.
