Summary:An imaging device includes a fuser assembly including a heat transfer member and a backup member positioned to engage the heat transfer member thereby defining a fusing nip therewith. A motor is coupled to the backup member for rotating the backup member. A controller coupled to the fuser assembly controls the motor using time-based commutation for a period of time to rotate the backup member at a slower speed relative to a speed for performing a toner fusing operation. In memory, at least one lookup table is stored having entries which, when sequentially accessed by the controller during the time-based commutation, are used to generate one or more drive signals for the motor to cause current flowing through windings of the motor to have a substantially sinusoidal waveform.
