According to FreedomCAR 2020 targets, the service life of traction motors should be greater than 15-years of continuous operation (30 kW), while sustaining short bursts (18 seconds) of 55 kW peak power. Given the discontinuous vehicle operation under varying ambient temperatures (-40°C to 105°C), the Achilles’ heel of permanent magnet traction motors is demagnetization.

In this presentation, MagNet will be used to simulate demagnetization due to current, temperature and a short-circuit fault, on a permanent magnet traction motor.
