    The invention relates to electrical engineering, namely, to brushless synchronous electric motors. S
    The purpose of the invention is to increase the efficiency and improve the starting characteristics of the electric motor, as well as improving its manufacturability.
    The drawing shows schematically an electrical block diagram of a proposed brushless synchronous motor associated with an exciter.
    A synchronous motor usually contains a stator with a three-phase winding 1 connected to the three-phase current network and a pole-shaped rotor with excitation winding 2, which is driven by the exciter, and shortly
    closed zi damper winding The pathogen has a winding 4 stator and a winding 5 of the rotor. An alternating current induced in the winding of the exciter rotor is rectified in a rotating rectifier 6, which is protected by an arrester 7 for protection against overvoltages, and excites the excitation winding 2 of the electric motor 0 For controlling the excitation, a thyristor 8 with an ignition device 9 is provided. A short-circuited damper coil 3 includes two parts 10 and 11. Parts 10 and 11 of winding 3 have a different number of turns and can be performed either with the opposite winding direction “or with the same winding direction, but connected counter-wise.

    During the operation of the electric motor, the voltage to the three-phase winding 1 and the excitation winding 2 with the voltage induced during the start of the synchronous electric motor in parts
    10 and 11 of the short-circuited damping winding 3 partially compensate each other and cause a short curly current, which in the case of arising fields is determined by the ratio of the number of turns of both parts 10 and
    11 windings 30 Due to the freely selectable coordination of the number of turns of parts 10 and 11 of winding 3, due to its given ohmic resistance, not only the voltage of the excitation winding 2 can be achieved, but also optimization from the point of asynchronous torque
    and an emerging moment under given conditions, even when this protective winding is decoupled with a full main field.
    The most simple design conditions can be provided for the benefit of the fact that the short-circuited fern winding is made partially two-wire, i.e. bifillary.
    The invention leads to an increase in the efficiency of a brushless synchronous motor and to an improvement in its starting characteristics. Invention Formula
