Electric motors are everywhere. They are in cars, planes, trains, boats and just about every other type of vehicle. Most electric motors use magnets to create a rotating field that powers the motor. However, there is now a new type of electric motor that does not use any magnets. This new motor was created by MAHLE and is certainly a more environmentally friendly and cost-efficient product than typical electric motors. But why does this magnet-free electric motor even exist?

Why are magnet-free electric motors important?

In recent years, there has been a growing interest in magnet-free electric motors. There are several reasons why they are becoming increasingly popular.

One reason is that they are more efficient. Traditional motors rely on magnets to create a magnetic field. This magnetic field is used to rotate the rotor, which in turn creates torque. However, this process is not 100% efficient. Some of the energy is lost as heat and some is wasted due to friction. Magnet-free electric motors obviously do not rely on magnets but instead use an electromagnetic induction process to generate their rotational force. This process is much more efficient and results in less energy being lost as heat. Additionally, it also eliminates the need for lubrication, which can further reduce energy losses.

Another reason why magnet-free electric motors are becoming increasingly popular is that they generate less electromagnetic interference (EMI). EMI is a type of electromagnetic radiation that can cause problems with electronic equipment. Traditional motors generate a significant amount of EMI. This can interfere with the operation of nearby electronic devices. Magnet-free electric motors generate much less EMI, making them ideal for use in areas where electronic equipment is sensitive.

Magnet-free electric motors are also good for the environment. They reduce the use of rare Earth metals, and therefore decrease humanity's impact on natural resources.

Finally, magnet-free electric motors are much more durable than traditional motors. This is due to the fact that they do not rely on magnets, which can be susceptible to damage. Additionally, the lack of moving parts reduces the likelihood of mechanical failure.

Overall, magnet-free electric motors offer a number of advantages over traditional motors. They are more efficient, generate less EMI and are more durable. As such, they are an ideal choice for a variety of applications.

The benefits of MAHLE’s new design

Electric motors are the workhorses of industry, powering everything from fans and pumps to conveyors and assembly lines. While the basic design of an electric motor has remained largely unchanged for over a century, MAHLE engineers have developed a new magnet-free electric motor that offers a number of advantages over traditional designs.

The new MAHLE motor is based on the company's induction motor technology, which uses electromagnetic induction to generate the rotational force necessary to power an electric motor. Induction motors are typically more efficient than other types of electric motors.

The benefits of MAHLE's new magnet-free electric motor include:

· Cost savings: The new motor is much more efficient than traditional electric motors, which means it will require less energy to operate. This will lead to lower operating costs for businesses and consumers.

· Resource security: The new motor doesn't use rare Earth metals, which are becoming increasingly scarce. This will help to ensure that electric motors can continue to be manufactured without the need for these materials.

· Environmental compatibility: The new motor is more efficient than traditional electric motors, which means it will generate less pollution. Additionally, the fact that it doesn't use Earth metals makes it a more environmentally friendly option.

· High overall efficiency: The new MAHLE motor has an overall efficiency of 95%, which is significantly higher than the average for other types of electric motors. This level of efficiency was only previously achieved by Formula E racing cars.

· Suitable for all vehicle classes: The new MAHLE motor is designed to be compact, making it suitable for use in a wide range of vehicles, including cars, trucks and buses.

· Wear-free: The new motor uses an inductive power transmission, which means there are no moving parts that can wear out over time. This makes the new motor practically maintenance-free and gives it a much longer lifespan than other types of electric motors.

What does a more efficient electric motor mean for the EV industry?

The global electric vehicle (EV) market is expected to reach $1,105 billion by 2030. The industry is driven by the increasing focus on curbing carbon emissions and air pollution. Additionally, the falling cost of EVs and advances in technology are projected to fuel market growth over the forecast period.

More efficient electric motors are a key component of EVs, and their development is crucial for the continued growth of the EV market. More efficient motors can lead to longer range for EVs as well as reduced charging times. Additionally, they can help to lower the overall cost of ownership for EVs.

The new MAHLE magnet-free electric motor is an innovative design that offers several advantages over traditional electric motors. These benefits make it an ideal choice for a wide range of applications where cost savings, resource security, environmental compatibility and high overall efficiency are priorities.

MAHLE’s highly efficient magnet-free electric motor is an important development in the EV industry. Magnet-free electric motors are more efficient than traditional motors, and they have the potential to revolutionize the entire EV industry by making EVs more affordable and accessible.
