BLDC machine
Extends from Partials.DriveBase (DC drives base).
Information
Complete brushless DC drive with inverter.
For block (rectangular) non-pulsed modulation the input to vPhasor[1] is arbitrary and has no influence.
For pulsed rectangles vPhasor[1] can be used
a) to simulate time-average voltage amplitudes.
b) to determine the ratio of on- to off-time when using a pulsed modulator.
where 0 < vPhasor[1] < 1.
The rectangle width is a parameter with default value 2/3, corresponding to '2 phases on, 1 phase off' at a time.
Note: for machines with gear w_start denotes the initial angular velocity at the generator-side!
