Description of the Invention () The present invention relates to the structure of a motor. In detail, it refers to a motor driven by magnetic force. According to the types of motors used, there are quite a lot of types, such as DC split-motors, AC-DC general-purpose motors, induction motors, stepper motors, etc. However, the original application of them is nothing more than the use of electromagnetic principles, and AC-DC current will be used as the driving power. Make the rotor mechanism change the magnetic field to form torque. This kind of system uses electric energy as the driving energy. Some companies have researched and developed motors without electric energy. For example, National Announcement No. 309674 "Method and Structure of Permanent Motion of Magnetic Energy Motors" , It uses the rotating member to generate magnetic conduction with the inner magnetic core, and forms different magnetic poles at different rotation positions, and then rotates through the interaction of the outer field magnet; however, the above-mentioned magnetic conduction between the rotating member and the inner magnetic core It must undergo precise calculation before it can receive the magnetic conduction effect of the field magnet, so that the rotating part can change the magnetic pole smoothly due to the conduction effect; in other words, the relative position and magnetic force of the three cores and the field magnet in the rotating part are within the moment of load. Under the limitation of the conditions, the possibility of turning only 15; and the structure is a single speed and torque value, and can not be arbitrarily Change of mind. For this reason, the main object of the present invention is to provide a magnetic-type drive motor that can generate a permanent motion without the need for a power source. Another object of the present invention is to provide a magnetic drive motor, which can easily change the torque and the rotation speed. That is, a magnetic drive motor of the present invention has a rotating shaft, and a plurality of first magnetic induction pieces protrude from the peripheral side of the rotating shaft, and a first magnetic piece is provided on the side end of each first magnetic induction piece; There are a plurality of second magnetic induction sheets, each of the second magnetic induction sheets is distributed on the peripheral side of each of the first magnetic induction sheets, and the national standard (CNS) A4 specification of the 3-wave paper scale is applicable ( 2 丨 0X297 mm) — m-11 f -'- OJ11-Jin nn β ^ —j (Please read the notes on the back before filling out this page) Printed by the Consumer Sample Cooperative of the Central Sample Rate Bureau of the Ministry of Economic Affairs A7 B7 5 2.
