Title: Method for detecting rotational position of brushless dc motor, rotational position detector and refrigerator
Inventor: OMURA NAOKI
IPC: H02P21/22
Filed: 2002-01-10
Abstract: <P>PROBLEM TO BE SOLVED: To detect the rotational position of a rotor accurately regardless of the temperature variation of a motor.  <P>SOLUTION: A current difference operating section 21 determines current differences ΔIdm and ΔIqm between estimated currents Idm and Iqm calculated at a motor model current operating section 20 based on the equivalent model formula of a motor and detected currents Id and Iq. An integration adjuster 24 integrates the current difference ΔIqm to determine a speed electromotive force em. A proportion adjuster 26 and an integration adjuster 27 perform the proportional operation and integration of the current difference ΔIdm, respectively. Based on proportion/integration results and the speed electromotive force em, an estimated speed electromotive force em and an estimated rotational position θm are obtained. Since the integration adjuster 27 is provided additionally, estimation accuracy is enhanced.  <P>COPYRIGHT: (C)2003,JPO
