Abstract: A paper feeding mechanism, an image forming apparatus employing the same and a paper feeding method thereof are disclosed. In an image forming apparatus capable of performing the printing operations at a particular printing operation that calls for a particular corresponding reference paper feeding speed, a reduction in the paper feeding noise may be achieved by providing a pickup roller operable at pickup/feeding speed that is slower than the reference feeding speed called for by the particular printing speed and a registration roller operable at the reference feeding speed. In addition, the pickup period at which the pickup roller picks up successive sheets of paper may be shortened to account for the slower operating speed of the pickup roller.

Abstract: A method of estimating inductance of a permanent magnet synchronous motor (PMSM) includes injecting a signal having a frequency differing from an operating frequency of the PMSM into the PMSM during sensorless operation, sensing magnitudes of current responses to the injected signal, and estimating an inductance value at which the magnitude of the sensed current response is minimal to be an actual inductance value of the PMSM, thereby estimating inductance used in the PMSM regardless of position estimation error of the PMSM and thus more accurately and reliably estimating inductance of the PMSM.
