Abstract
A dc brushless electromagnetic rotary machine, such as a dc electric motor, a dc electrical generator, includes a rotor having a permanent magnet which is cylindrical outer peripheral surface magnetized in the same polarity. The outer surface faces armature cores fixed on the inner cylindrical surface of a casing frame forming a stator of the machine. In the structure, the magnetic flux emanating from the rotor magnet passes the armature cores and returns to the magnet from a position other than the armature cores. The armature core is provided with coil windings wound thereon in such a manner that a portion of the windings is included in the air gap formed between the rotor magnet and the cores. Additional magnetic flux induced in response to current flowing over the armature windings causes the main magnetic flux generated from the rotor magnet to be turned in the same way irrespective of the angular position of the rotor. Consequently, continuous rotation of the rotor will be accomplished in the case of dc motors, and continuous generation of dc power will be achieved in the case of dc generators.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
