Title: Driver of sensorless brushless motor
Inventor: MATSUOKA ATSUSHI
IPC: H02P6/18
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce vibrations and noises by a method wherein non-application sections are produced in voltages supplied to stator windings and a relative position between a stator and a rotor is detected. SOLUTION: A rotor position detecting means 11 detects the zero-cross points of the induced voltages of respective phases in accordance with phase application voltages formed into approximate sine waves and supplies rotor position signals to a zero-cross point period calculating means 12 and an excitation time correcting means 13. The means 12 calculates the periods of the zero-cross points and the means 13 corrects the phases of the phase application voltages so as to have the coincident phases of the induced voltages with the phases of stator currents applied to stator windings 4, 5 and 6 in accordance with the calculated periods and the position signals. Then a non-application section producing means 14 outputs commands to a application control means 15 at the timings when the applications to the windings 4, 5 and 6 are discontinued to produce the non-application sections in accordance with the corrected phases. The means 15 supplies excitation signals to a motor driving means 2 in accordance with the commands and the corrected phases, and the means 2 applies the phase application voltages which are formed into approximate sine waves to the windings 4, 5 and 6.

Title: Magnetic field generating apparatus
Inventor: KAKIUCHI SHIYUNJI
IPC: H01F6/00
Filed: 1984-04-16
Abstract: PURPOSE:To minimize entire resistance of coil by providing the weld-connecting portion to the area where the magnetic field is lowest and thereby keeping the superconductive condition at the area near the welding portion on the occasion of arranging a plurality of superconductive coils on the same axis and connecting such superconductive coils at the lead wires with the welding process. CONSTITUTION:When a current 10A is applied to a coil, a magnetic field of 0.5T is generated on the Y axis. In this case, distribution of magnetic field in the area near the coil reaches about 1.2T at the magnetic field inside the main coil 3 and sub-coils 4, 5. Meanwhile, the magnetic field at the external diameter side (near the point A) of main coil 3 is only about 0.03T. Therefore, the connecting portion 6 connected by welding is arranged at the external diameter side of the main coil, as the area where the magnetic field generated by the main coil 3 and subcoils 4, 5 is minimized. In case the weld-connecting portion 6 is arranged at the external diameter side of main coil 6, the experience magnetic field of superconductive lead wire of which H-Ic characteristic is deteriorated by welding is about 0.03T. In this case, since a current supplied is 10A, the field intensity H=0.03T and I=10A at the designed point and sufficient superconductive characteristic can be obtained even after deterioration.
