Abstract: The motor and method are intended for movement of spacecraft in the outer space. The motor consists of a corpus (7) of non-magnetic material, to which are fixed the magnetic cores (1 and 2), made of ferromagnetic material, and coil windings (3 and 4) and insulating reels (5 and 6) are mounted on their cores. A coil winding (9), the reel (10) and the wear-resistant ring (11) are fixed to the corpus (7). A movable part (anchor) (8) is made of ferromagnetic material and moves freely, longitudinally, in the wear-resistant ring (11) made of non-magnetic material. The front surfaces (12, 13 and 14) of the anchor (8) and the front surfaces (15 and 16) of the fixed magnetic cores (1 and 2) are wear-resistant. The excitation windings (3, 4 and 9) made of conductor or superconductor are connected to DC sources (17, 18 and 19), respectively, by power cables (23, 24 and 25), (26, 27 and 28) ), (29, 30, and 31). The switching on, switching off and controlling of the power supply of the winding coils (3, 4 and 9) is carried out by switching blocks (20, 21 and 22) connected to the commutation units (32) by means of control cables (37, 38 and 39). The position of the anchor (8) is monitored by means of sensors (33, 34, 35 and 36) connected to the commutation unit (32) via signal cables (40, 41, 42 and 43). The essence of the motor and the method of motion is that it uses an electromagnetic system consisting of a fixed and movable part. In the case of simultaneous pulsed supply of the excitation windings, currents flow through them, which excite magnetic fluxes creating electromagnetic forces, so that in the first stationary magnetic core and the anchor (movable part) the electromagnetic forces are repulsive, and in the second stationary magnetic core and anchor there are electromagnetic forces of attraction by which the anchor performs a progressive motion and moves to the pole of the second stationary magnetic core. At the appropriate ratio of the electromagnetic forces to the masses of the movable part (anchor) on the one hand, and on the other of the fixed part including both the stationary elements of the electromagnetic system and the whole apparatus, on impact the resulting electromagnetic force is converted into mechanical force, and it is external to the whole system and changing the impulse of the system results in motion and displacement of the whole system, after which the polarity of the applied voltage is changed on the excitation coil of the second stationary magnetic core, the direction and the magnitude of the flowing current, and the excitation coil of the first stationary magnetic core changes the magnitude of the current flowing, as a result the anchor repulses and moves to a certain distance from the pole of the first stationary magnetic core, after which the whole process is repeated as the motion speed of the apparatus is constantly increasing. In the reverse sequence of action, a braking mode is performed, and the motion speed of the apparatus is constantly reduced. When changing the direction of positioning of the pulse electromagnetic-dynamic motors in the system, the direction of motion of the spacecraft changes. The required electricity is provided by its own source and by solar panels that convert solar energy into electricity.
