We have been called onto the race track for our second race of the day. Having not managed to successfully repair the custom built motor controllers we are using the stock controllers bought with the machines.
There are two risks associated with this. The first is that the operating voltages for these controllers is limited to around 60v. If the turbines spin too fast their voltage will exceed this and risk damaging the controllers. This was the main reason for using our own controllers.
The second problem is that the stock controllers have a limited output current and during testing the vehicle barely started when using them. The custom controllers are being repair by the team whilst we attempt our race so if they are ready we'll use these in a further race.
Team morale is at its lowest and despite working hard to get the car working again I think that all of our expectations are low at the moment.
