Title: Detector for detecting rotation angle for synchronous rotating machinery
Inventor: HORI MASAFUMI
IPC: H02P6/16
Filed: 2002-06-06
Abstract: <P>PROBLEM TO BE SOLVED: To shorten the time (time to open driving) from closing of power source up to synchronization, compared with a conventional one, so as to obtain inherent torque and responsiveness of a rotating machine in a short time after the closing of a power source.  <P>SOLUTION: An encoder 4 outputs one Z phase (index pulse) serving as a reference for synchronous electrification in every 45° rotation of a rotor 6 (every one cycle of electrification in U, V and W phases). The open driving is thereby transferred to synchronous driving within the 45° rotation of the rotor 6 after the feed of the power. Resultingly, the inherent torque of the rotating machine 1 and the responsiveness are obtained in the short time after the feed of the power. Since the encoder 4 outputs one Z' phase (semi-index pulse) in every one-rotation of the rotor 6, the rotation angle of the rotor 6 with respect to a stator 7 can be known based on the Z' phase, and the rotation angle where the rotor 6 outputs the Z phase, and the rotation angles where the rotor 6 outputs A and B phases can be known, too.  <P>COPYRIGHT: (C)2004,JPO
