In-Wheel Motors for a Hydrogen Car
A key feature of the Rasa hydrogen fuel cell car developed by Riversimple is its four in-wheel electric motors, which were developed by PMW. These thin, powerful pancake motors had to meet a number of demanding requirements, including the need to have an integral mount for the brake disc.
Challenges
- High Power
- Ultra Flat
Results
- Application Optimised XR Design
- Integrated In-Wheel Motor
Further constraints were the use of conventional, externally mounted disc callipers, a low target weight and the need for the whole package to fit within a 15 inch wheel rim. The XR32-11 in-wheel motors produced by PMW allow the car to use regenerative braking, recapturing over 50% of the kinetic energy, and using a bank of supercapacitors in the front of the car to store the electrical power generated
The brushless DC motors help to keep the weight of the vehicle down, as they deliver unparalleled performance for their size, with each capable of producing a peak torque as high as 160 Nm while weighing only 17 kg
