Filed:

Mar 31, 2006

Appl. No.:

11/394778

Inventors:

Aaron Lambert - Lexington KY, US

International Classification:

H02P 3/00

US Classification:

318466000

Abstract:

In a laser printer, methods and apparatus include commutating a brushless dc motor having three windings. A controller receives discrete motor position signals, such as from hall-effect or FG sensors, and extrapolates motor position between the signals. It commutates the motor based on the extrapolated motor position and updates motor position whenever an actual discrete signal is received. Drive signals from the controller to the motor are such that a current flowing in any of the three windings follows a generally sinusoidal waveform. High and low switches are provided per each winding of the three windings and are cumulatively switched according to an extrapolated motor position based multiplier applied to a pulse width modulation duty cycle. In this regard, lookup tables, counters, registers and the like are provided. An engine card of the printer includes an ASIC with a power driver for use with generally off-the-shelf brushless dc motors.

US Classification:

Abstract:

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.
