Motor theory of operation demonstration model

The utility model belongs to the technical field of the teaching aid, especially, relate to a motor theory of operation demonstration model, by the base, link the frame on the base, the first plastics pivot of base center, first plastics change epaxial first U -shaped magnet, the first vertical company of U -shaped magnet in first plastics pivot and the opening upwards, even there is the pivot of second plastics on the crossbeam of frame, the pivot of second plastics the below of crossbeam and with first plastics pivot just to setting up, even there is second U -shaped magnet second plastics pivot bottom surface, the vertical company of second U -shaped magnet is in the pivot of second plastics and open side down, first U -shaped magnet and second U -shaped magnet are non - contacts, second U -shaped magnet opening part external diameter is less than first U -shaped magnet opening internal diameter, when external force made first U -shaped magnet rotatory, second U -shaped magnet was also and then rotatory under magnetic field, vividly demonstrated the theory of operation of motor, the utility model discloses simple structure, reasonable in design, the student of being convenient for understands, arouses student's interest in learning.
