FIELD: electricity.SUBSTANCE: invention relates to the field of electrical engineering and transport machine building and may be used in development of mechanisms, in which it is necessary to change torque and rotations of an output shaft of an electric motor. According to this invention, in an electric motor a differential gear is used as a converter of transmission ratio, and the gear comprises one input and two outputs, the input of which is connected to a rotor of the electric motor, one of outputs, to which a high torque is sent, is connected with an output shaft, and the second output is connected with the second rotor, which is inductively connected with the rotor of the electric motor, and in case of their mutual rotation, it generates electric energy, and force arising at the same time, by changing which, through variation of inductive connection between rotors, the speed up rate may be controlled, as well as output shaft rotation speed, partially blocking the gear, aims to reduce mutual relative opposite rotation of the electric motor rotor and the second rotor. The second rotor is also connected with a speed-up coupling, which is connected with the body by a response part, and preventing rotation of the second rotor to the side opposite to direction of the electric motor rotor rotation.EFFECT: multiple increase of electric motor torque in case of speeding.1 dwg |
