In order to adapt to the EV requirements, bearing technology is changing dramatically in terms of design and operability, with suppliers looking to provide OEMs with more powerful and durable components. What are the main developments in optimised bearings and how can they boost electric motor performance?

Automotive IQ would like to share with you this article on "E-Drive Bearings, Reaching Another Level" that you can download here free of charge and learn more about the developments.

Article discusses the following:

• Hybrid Ceramic Bearings 
• Taper Roller Bearings
• Needle Roller Bearings
• Bearing related developments 

Ian P. Brown, Ph.D. Associate Professor from Illinois Institute of Technology conducted a study on Life Without (or Little) Rare Earth Permanent Magnets: A Survey of Electric Machine Possibilities and provides results in this exclusive presentation. You can download it here free of charge.

Highlights of the presentation include:

• Permanent Magnet Synchronous Machines with No or Reduced Rare-Earth Content
• Induction Machines with Copper Rotors and their challenges
• Wound Field Synchronous Machines: Research Traction, High Power Density, Challenges & Improvement Opportunities
• Optimal Design of Non-Rare Earth Traction Motors

Axial flux motor offer better power and torque than conventional motors. However, they are not widely used due to the lack of manufacturing and design experience in the automotive industry. Find out more about the subject from a past presentation on "Axial Flux Motors Manufacturing and Application" presented by the CEO of Phi-Power, Dr. Michael Lampérth.

Topics covered in the presentation include:

• Better performance – less material
• Changing the motor diameter
• Position of electric motor
• Manufacturing
• Pros and cons of Electrical steel and SMC
