Here you see the 3 phases of the brushless DC (BLDC) motor
Red at 0 degrees, blue at 120 degrees, green at 240 degrees
These are represented in the animation by the 6 coloured "doughnuts"
They are "solenoids" or coils of wire
There are 6 since there are 2 for each phase on opposite sides of the rotor
so you have a complete magnetic field passing through the center of the motor
in 3 directions at 120 degrees to each other.
We have the rotor which has a fixed magnet (show above spinning as shaded grey) and would be attached to the output shaft.
The three phases red, blue and green are each producing an alternating field
and the three together produce a rotating field
which pulls the rotor magnet round and thus the shaft.
This is about making a brushless motor more efficient by making it possible to tune a controller to the motor's specific internal characteristics.
Current brushless motors are quite efficient already.
In the region of 80% and up.
I would estimate the resonant controller would increase this to the 90% region.
This would increase the range and top speed of the car.
This is about reducing complexity and cost of brushless motor controllers.
Current technology for high power electric motors, the ones used in electric vehicles,
employs multiple power supplies to enable the controller to driver the motor reliably.
The simple split-rail controller takes advantage of the fact that the high power supply
which powers the Mass-EV is an isolated battery supply.
This makes the controller very simple and consequently much cheaper.
This is about making an efficient micro-turbine engine.
Normally in a gas turbine engine a compressor is powered directly from the turbine via a connecting shaft.
This uses high speed electric motors and generators combined with an intelligent controller
so the engine is far more efficient than has been achieved in a turbine engine suitable for cars.
The pressure in the engine is maintained at all output levels
by independently controlling the compressors and turbines to ensure maximum efficiency.
