BOSTON, 23 June 2023: The electric vehicle (EV) market is growing rapidly, and with it, the demand for electric motors. Traditional radial flux motors are still the dominant form of motor in EVs, but there are a number of emerging alternatives that offer potential advantages in terms of power and torque density, cost, and sustainability.
Axial Flux and In-wheel Motors
One of the most promising emerging technologies is the axial flux motor. These motors have the magnetic flux parallel to the axis of rotation, rather than perpendicular as in radial flux motors. This design results in a number of advantages, including increased power and torque density, a pancake form factor that is ideal for integration into various vehicle platforms, and the potential to use less expensive materials.
Another emerging technology is the in-wheel motor. These kinds of motors are located in the wheels of the vehicle, and they provide a number of advantages, including improved efficiency, reduced weight, and the potential to simplify the powertrain. However, in-wheel motors also present some challenges, such as the need for high-voltage components and the difficulty of cooling the motors.
IDTechEx’s latest report, “Electric Motors for Electric Vehicles 2024-2034,” provides a comprehensive analysis of the electric motor market for EVs. The report covers a wide range of topics, including the different types of electric motors, the market drivers and challenges, and the future trends.
The report finds that the demand for electric motors is expected to grow significantly in the coming years, driven by the growth of the EV market. However, the report also notes that there are a number of challenges that need to be addressed in order to fully realize the potential of electric motors. These challenges include the need for more efficient and affordable motors, the development of new materials, and the improvement of the thermal management of motors.
Overall, the report provides a valuable overview of the electric motor market for EVs. It is a must-read for anyone interested in the future of electric vehicles.
