“IMPROVEMENT INTRODUCED IN ELECTRIC MOTOR”, foreseeing an electric motor indicated by reference (M) essentially comprising a stator (1), incorporating at least a coil (2) which is positioned or mounted in parallel with at least a respective fixed magnet (3), and when the current (C) is enabled, the flow (F) created by the coil (2) presents the same magnetic signal that the flow for the fixed magnet (3), closing the circuit though the air gap area (4), in the direction of rotor (5), to other air gap area (4) and to the core, the same occurring with the flow for the fixed magnet (3), passing from the core to the stator, to the air gap (4), to the rotor (5) and to other air gap area (4) and again to the core, then closing the circuit, creating two flows (F) that are combined to promote the rotation for the rotor (5); on the other hand, when the current is disabled, the flow for the fixed magnet enters in toroid setup, such as indicated by reference (F1) going through the core of the stator (1); foreseeing a fixed magnet (3) in the stator (1) in parallel with the coil (2) of said stator, and when the motor is not powered, the flow for the fixed magnet (3) is in closed circuit, inside the stator (1), since when the motor is enabled, with DC current, said current flows through the coil (2) of the casing or rotor (5) and through stator of field coil (1), generating a flow in the stator (1) resulting from the passage of the current through the coil (2); the direction of said flow generated by coil (2) is opposed to the direction of current through coil; the direction of said flow generated by coil (2) is opposed to the direction of magnet flow, which is in said closed circuit; when both flows meet, these repel each other and are conducted to the poles and air gap (4) of the motor to interact with the coil flow (2) of the casing or rotor (5) to produce the torque or pair.
