The invention relates to electric machines and can be used for reconstruction and design of new powerful synchronous motors. A synchronous motor comprises a stator with a winding, a rotor with a damper winding and coils of winding which are connect one to another by crosspieces. Each pole comprises one coil, the coil are connected by crosspieces next but one and form two equal groups of sequentially consistent poles. Each pair of neighbor coils is connected by a circuit of in series connected a capacitor and a resistor, an adjustable discharge resistor is connected to the start of coils of first and the last poles. According to the invention the circuit design allows extending an action aria of resonance phenomena and therefore improve engine startability, ly simplify a design of rotor magnetic system, therefore to decrease costs for thereof manufacturing, provides start of electromechanical systems with hard start, avoid an idle start, in particular cases to use engines with lesser excess power, allowing reduce . |
