A motorized shade comprising a motor adapted to lower or raise a shade material for selectively covering an architectural opening based on a position of the sun. The motorized shade comprises a controller adapted to drive the motor phase according to a startup sequence by ramping up amplitude form an initial amplitude to a startup amplitude and ramping up frequency from an initial frequency to a drive frequency, drive the motor phase according to a full drive sequence to move the shade material by driving the motor phase according to a sinusoidal waveform at a set maximum amplitude and at a drive frequency, and drive the motor phase according to a wind down sequence by reducing frequency from the drive frequency to an end frequency and reducing the amplitude from the maximum amplitude to an end amplitude.
