FIELD: electromagnetic propulsors for spatial motion of tele-controlled vehicle in liquid media. ^ SUBSTANCE: proposed electromagnetic propulsor includes laminated ferro-magnetic cylindrical core of stator with three-phase encapsulated winding rigidly secured in vehicle; revolving part is made in form of hollow laminated core with short-circuited copper winding; propeller blades are located inside core of revolving part. Each blade is made in form of three-layer structure: two outer layers are made from brass, bronze or plastic and inner layer is made in form of permanent magnet made from sintered powder material of high coercive force; number of blades is even and is equal to number of poles of stator winding. ^ EFFECT: enhanced conversion of power due to avoidance of use of reactive power from power source. ^ 2 dwg
