FIELD: electrical engineering. ^ SUBSTANCE: invention relates to electrical engineering and electric machine building. According to the first version of the invention, the electromagnetic dc motor contains a stator with three coils, placed in it through 120 degrees, and a rotor, consisting of two ferromagnetic and two nonmagnetic parts, joined into a ring in a certain order, and with two slots on the nonmagnetic parts, as well as three pistons adjoining the said slots, interacting with the on-contacts of the stator coils. The rotor, through an inner serrated part, adjoins three stem gears. According to the second version, the electromagnetic dc motor has a stator with three coils, placed in it through 120 degrees, and a rotor, consisting of two ferromagnetic and two nonmagnetic parts, joined into a ring in a certain order. At the ends of each stator coil there are electromagnetic sensors which control positioning of ferromagnetic parts of the rotor in the said coils and interact with an electronic device for powering the coils of the motor. The motor torque depends on the diametre of the rotor, and from voltage across the coils. The motor does not have limited speed of rotation and has flat structure, which allows for its use in devices where other motors cannot carry out the required function. ^ EFFECT: provision for constant transmission of torque from the rotor to the motor shaft. ^ 12 cl, 2 dwg, 1 tbl |
