SUBSTANCE: present invention relates to electrical engineering and electromechanics, particularly to electric machines, and pertains to distinct features of design of a planetary electric motor - reducing gear with a lever for controlling the commutator. To increase excentricity of rotation of the commutator by several times compared to excentricity of the satellite - armature, the proposed planetary electric motor - reducing gear employs a lever for controlling the commutator. The proposed planetary electric motor - reducing gear has a planetary gear system in form of a friction pair or planetary reduction gear, the first step of which executes functions of the stator and satellite - armature of the electric motor. The commutator rotates synchronously with the satellite - armature. The stator and satellite - armature are fitted with solenoid coils, which shift the satellite - armature about the point of maximum entrance of teeth of the wheel and primary pinion of the planetary reduction gear into each other, or about the point of contact of the friction pair. The commutator, which can rotate excentrically about the housing, provides for phase shifting of the electromotive force of the electric motor and closes the solenoid coils of the stator and satellite - armature. The lever for controlling the commutator has different arms, the end of the shorter one of which engages the statellite - armature, and the end of the longer one enters the collector, providing for its rotation with excentricity, which exceeds excentricity of rotation of the satellite - armature. The commutator can be used with butt-end and cylindrical arrangement of contacts. The current input and output elements of the commutator do not rotate, they only oscillate.
EFFECT: improved operation of a planetary electric motor - armature, reduced spark formation of the brushes and electric arc from commutator contacts, as well as provision for wide regulation of frequency of rotation, torque and reversing the electric motor.

SUBSTANCE: present invention pertains to electrical engineering and can be used in parametric machines in the electrical energy industry as electric generators and electric motors, for example on electrical power stations. The synchronous generator-compensator is a combined electrical machine, the circuit of which has an electronic frequency converter, with power corresponding to an asynchronous motor. On one axle of the synchronous generator-compensator there are series-arranged rotors of the drive motor, synchronous generator with a thyristor-type self-triggering system, and the asynchronous motor with a short-circuited rotor. The rotor of the asynchronous motor is in form of a flywheel with a large diameter, radius R and mass, which matches up the radius r and mass of the rotor of the synchronous generator, respectively, calculated using the mechanical resonance formula. The ratio R/r is chosen in accordance with the Fibonacci number sequence. The output of the synchronous generator and the input of the stator of the asynchronous motor are connected through a frequency converter, supplying the asynchronous motor with current, with discrete synchronisation of the frequency of current from the synchronous generator and frequency of the angular impulse of the asynchronous motor. The circuit of the frequency converter has massive capacitors, with provision for mechanical positive feedback from the rotor of the asynchronous motor to the rotor of the synchronous generator due to the single axle of the rotor of the asynchronous motor and the synchronous generator. The rotor of the asynchronous motor has ratio of the width to its radius in accordance with the Fibonacci number sequence, in succession to the chosen ration R/r. The diameter of the asynchronous motor is increased, corresponding to the rotor, with provision for clearance between the stator and the rotor of 1-3 mm. The method of operation of the synchronous generator-compensator is implemented, as is described in the material of the claim.
