This is the 5500kV sensored brushless motor installed in the anglewinder configuration.

The motor will be operated at 7.5V suggesting a maximum rotational speed of 41,250 rpm.

With a gearing ratio of 31:13 (or is that 13:31?) and a tyre diameter of 20mm, this rpm corresponds to a linear speed of circa 18m/s. Well that’s the theory - actual speeds will be measured at the track using the new speed trap with digital read-out (as discussed here on a separate thread).

The idea behind the brushless project is to explore drivability of brushless motor driven cars at moderate speeds and then to explore the limits of the performance envelop at higher speeds.

The neat mechanical install should provide a good starting point.
