An image forming apparatus may include an engine portion used to perform an image forming job, a step motor configured to start the engine portion, a driver including a resistor that measures current that flows to a coil of the step motor and is configured to provide a predetermined constant current to the step motor, and a drive controller configured to measure a load level of the step motor based on a voltage value of the resistor and to control the driver to provide the constant current that corresponds to the measured load level.

Image forming apparatus, motor control apparatus, and method of controlling a motor

An image forming apparatus includes an engine portion configured to perform image forming, a direct current (DC) motor configured to mechanically operate the engine portion, a driver including a resistor to measure current that flows to the DC motor according to the measured current and configured to provide a predetermined voltage to the DC motor, and a drive controller configured to measure a driving speed of the DC motor based on a voltage value of the resistor and to control the driver to provide a voltage that corresponds to the measured driving speed to the driver.
