Title: combinelow power motor and generator
Inventor: KIM YONG SIK
IPC: H02K99/00
Filed: 2021-03-11
Abstract: The present invention aims to develop a prime mover capable of operating a motor without electric power. Cylindrical magnetic plates connected with axes at both sides are provided with bar-shaped magnetic plates arranged at both ends in the middle thereof at regular intervals. The two cylindrical magnetic plates are provided with bearings on ends at the two axes to facilitate rotation. Timing gears are arranged on the two axes between the bearing and the cylindrical magnetic plates to keep the two axes by a predetermined space. In the case of cylindrical magnetic plates connected to axes of the timing gears, the two cylindrical magnetic plates have different polarities and are arranged to engage each other at regular intervals. Accordingly, due to the different polarities of the two magnetic plates, attraction is generated at the front where the two magnetic plates meet. When the two cylindrical magnetic plates engage inward, an auxiliary magnetic plate (46) is inserted between the cylindrical magnetic plates in a rear section where the cylindrical magnetic plates are disengaged so that the cylindrical magnetic plates are separated into upper and lower magnetic plates. It is difficult to separate the cylindrical magnetic plates due to the generated attraction. To solve this, the auxiliary magnetic plate has an N polarity at an upper side and an S polarity at a lower side of the upper and lower magnetic plates so as to achieve natural separation. Accordingly, the two magnetic plates can help smooth rotation.
