Hall Effect Analog to Digital
Conversion.
The data is converted simply with the use of OpAmps. The system in use is complicated a little by using 2 sets of 3 Hall Sensors. This allows adjustment of the timing for each step.

Pulse Width Modulation
Logic Gates
A Picaxe micro supplies a continuous adjustable PWM duty cycle to control the motor voltage. The period is set at 15600 cycles per sec.
Only the 3 High Side mosfets are switched with the PWM signal.
