Motor control circuitry reduces the amount of driving voltage profile data
stored in a profile datastore to completely rotate the phased motor. The
stored driving voltage profile data defines driving voltages samples
applied during a limited portion of the electrical period required to
completely rotate the phased motor. For example, in one implementation,
only one-sixth of the electrical period is defined and stored in a
profile datastore. The driving voltage samples for another three-sixths
of the electrical period are derived from this one-sixth profile (e.g.,
reversing, inverted, reversed and inverted), and the driving voltage
samples for another two-sixths of the electrical period are based on
saturated levels at the power supply voltage and a neutral voltage (e.g.,
ground). The described motor control circuitry can also provide improved
torque at low power supply levels, particularly when saturated portions
of the driving voltage profile exceed sixty degrees.
