Motors & Thermal Management: Material Opportunities and Market Trends

Forum 6 | 19 September | 3:30pm-5:45pm

The componentry remains a key battleground in this shifting landscape. This session will focus on two key areas: the motors and thermal management solutions. A technical and commercial overview of traction motors will be provided; details around the trends and benchmarking the different types for each application.

Controlling the temperature of electric vehicle componentry is essential for the safety, performance, and lifetime of the powertrain. This session will focus on the thermal management of the battery pack and motor. An assessment of both active and passive methodologies will be carried out with a view to the necessary material adoptions and integration. Many OEMs are taking different approaches and these cases will be explored in detail with both a current market view and an outlook with more demanding performance requirements and shifting regulations.
Each session will be delivered by IDTechEx analysts who have conducted the underlying research. This research is based on interviews with key players, extensive travel for global conference and events, as well as visiting prominent players in this area. The classes will include technical introductions, benchmarking studies, value chain analysis, case studies, key player analysis, current market analysis, and a global outlook. The slides will be provided to the attendees and there will be time allotted for Q&A and audience networking.

For those attending.

Electric Motors For Land, Water & Air

Compiled by Dr Peter Harrop, Chairman, IDTechEx

  • E-machines in electric vehicles for land, water & air including hybrid and pure electric.
  • Traction motor terminology: ISG, BSG, synchronous external or internal rotor, asynchronous/ induction, switched reluctance, axial vs radial flux, PMAC, BLDC.
  • Basic uses: propulsion using a propeller or wheels, engine starting, regenerative braking.
  • Chasing High Power to Weight Ratio.
  • Why axial flux looks good in electric aircraft but PM synchronous get most orders.
  • Examples: Siemens, YASA, ELAPHE, Makani, Rolls Royce/Airbus, others.
  • Trend To Multiple Traction Machines In Vehicles.
  • 3:55pm - 4:20pm

Traction Motors: Technology Overview

Compiled by Dr Peter Harrop, Chairman, IDTechEx

  • Why PM dominates and where.
  • Why switched reluctance and its variants are gaining share from Le Tourneau.
  • Why induction motors are losing share and where they are still retained and why.
  • Why most options are pitching for 48V mild hybrid business: who, why?
  • Options to avoid rare earth price hikes and temperature issues with permanent magnets.
  • 4:20pm - 4:45pm

Voltage Trends & Technology Implications

Compiled by Dr Peter Harrop, Chairman, IDTechEx

  • Overview of voltage trends.
  • Huge 48V mild hybrid opportunity as they evolve into EVs.
