  1. Lightest & smallest form-factor electric motor versus power & torque

    delivered The YASA motor being held can produce 150kW of power but weighs 22kg. The Technology
  2. Power to weight ratio (kW/kg) • More than 4 X

    increase in power per kg of motor weight & 5 X in torque per litre of volume • This ratio keeps increasing with YASA topology World leading power & torque density 0 20 40 60 80 100 120 Toyota Prius YASA-750 Peak torque/volume (Nm/l) Cont. torque/volume (Nm/l) Torque to volume ratio (Nm/litre) 0 2 4 6 8 10 12 14 16 Toyota Prius YASA-400 Peak power/volume (kW/l) Cont. power/volume (kW/l) Power to volume ratio (kW/litre)

  4. 2006 • Dr. Tim Woolmer invents the YASA topology as

    part of his PhD at the University of Oxford 2009 • Company is incorporated • First orders for YASA-750 (1st YASA motor product) 2010 • Company achieves a record torque density of 30Nm/kg • 1st sample order from a global automotive OEM received 2011 • YASA motor is successfully tested to automotive standard • Company wins 1st contract with global automotive OEM 2012 • 2nd YASA motor product goes in to production with backorder • Company wins next phase of volume automotive OEM contract Company Milestones

  6. What Value Weight 25Kg Max Peak Power 100kW @ ~380V

    150kW @ ~720V Peak Torque >750Nm @ 360Arms Continuous Power 50 - 60kW @ 380V 70 - 90kW @ 720V Peak Efficiency >94% Speed Range Up to 2000rpm @ ~350V Up to 3000rpm @ >500V Size 350mm dia x 66mm Y750 Motor/Generator
  7. Tractor to Implement Initiative • Packaging of electric generator is

    an issue to OEM’s. • Particularly with the power & torque level delivered. • Economics are a challenge. • YASA clearly has a role in helping to solve those issues.
  8. YASA’s role • Working with OEM’s to help solve the

    issues: • Maximise power delivered versus size of electric motor/generator • Cost per kW of generated power delivered • Motors for generating power • Motors for traction • Motors for auxiliary equipment and implements • For the tractor to implement initiative • For hybrid electric solutions • For full electric • Reduced emissions at a reduced operating cost
