Abstract

PURPOSE:To simplify the construction of the rotary electromagnet and to increase the output efficiency of the electromagnet by forming a cylindrical parmanent magnet in a stator and inserting a cylindrical iron core into a cylindrical exciting coil thereby forming a rotor. CONSTITUTION:The cylindrical permanent magnets 1a, 1b alternately magnetized with opposite polarity on the inner peripheral surface are inserted into both ends of a cylindrical case 3 formed of magnetic material, and cylindrical exciting coil 2 is so arranged between the magnets 1a and 1b that the centers coincide with one another, thereby forming a stator S. A cylindrical iron core 5 fixedly inserted into an output shaft 4 rotatably inserted into the center of the case 3 is inserted into the coil 2, and magnetic pole pieces 6a, 6b confronting at a suitable interval the magnetic pole piece surfaces on the inner peripheral surfaces of the magnets 1a, 1b are projected, thereby forming a rotor R.
