Title: High-speed motor
Inventor: BAN ITSUKI
IPC: H02P25/08
Filed: 1991-10-30
Abstract: PURPOSE:To obtain a brushless motor, a reluctance motor and a stepping motor which have a high speed, a high torque and excellent efficiency. CONSTITUTION:At the time when electrification of one armature coil 32a is stopped through the intermediary of one switching element on the positive voltage side, magnetic energy is made to flow in a capacitor 46a of a small capacity, charged and held therein at a high voltage and a current falls quickly. An impression voltage on the next armature coil 32b becomes high due to charging of a capacitor 46b and, therefore, the current rises quickly. Only with the static energy charged in the capacitor, however, the rise of the electrification of the armature coil is insufficient due to a copper loss of the armature coil and an iron loss of a magnetic core. Therefore the electrification current is kept at a set value by a chopper circuit and a part of the magnetic energy of the magnetic core of the armature coil is charged and held in the capacitor 46 of the small capacity at the time of the stop of the electrification so that it may correspond to a chopper frequency. Thereby an energy loss due to the iron loss and the copper loss at the time of alternation of the electrification of the armature coils 32 is supplemented and the rise of the electrification current is made quick.

Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To avoid the effect of dispersion at the time of the formation of a LOCOS oxide film on the impurity concentration of a diffusing region for high-voltage resistance by setting the concentration peak of the one-conducting type diffusing region for high-voltage resistance at the position deeper than the deepest interface region of the LOCOS oxide film and a drain region. SOLUTION: The concentration peak CP of a one-conducting type diffusing region 3 for high-voltage resistance is set at a position deeper than the deepest interface region between a LOCOS oxide film 5 and a drain region 8. Most of the regional area shown in a shaded part is present in the region deeper than the interface region of the LOCOS oxide film 5. Even when there is dispersion in film thickness (arrow mark), the total amount of impurities in the diffusing region 3 for high-voltage resistance becomes more than the conventional amount. Therefore, even if there is dispersion in the LOCOS oxide film 5 in the depth direction, the impurity concentration of the diffusing region itself for high-voltage resistance has no dispersion in comparison with the conventional device.  Therefore, the voltage resistance characteristic of the horizontal high- voltage resistance MOSFET can be made uniform.
