The modulation waveform is generated using Hall signals. The modulation waveform is then compared
with the triangular wave and a sine-wave PWM signal is generated.
The time (electrical angle: 60°) from the rising (or falling) edges of the three Hall signals to the next
rising (or rising) edges is counted. The counted time is used as the data for the next 60° phase of the
modulation waveform.
There are 32 items of data for the 60° phase of the modulation waveform. The time width of one data
item is 1/32 of the time width of the 60° phase of the previous modulation waveform. The modulation
waveform moves forward by this width.
In the above diagram, the modulation waveform (1)
'’ data moves forward by the 1/32 time width of the
time (1) from HU:
↑ to HW: ↓. Similarly, data (2)
' moves forward by the 1/32 time width of the time (2) from
HW:
↓ to HV: ↑.
If the next edge does not occur after the 32 data items end, the next 32 data items move forward by the
same time width until the next edge occurs.
The phases are matched between every rising edge of the HU signal and the modulation waveform. The
modulation waveform is reset in synchronization with the rising edge of the HU signal at every electrical
angle of 360°. Thus, when the Hall signal rising edge is off-position or during acceleration or deceleration,
the modulation waveform is non-consecutive at every reset.
