FIELD: electro-mechanical engineering, can be implemented for manufacturing and maintenance of three-phase asynchronous engines, operating in accordance to scheme of one-phased connection to electric power grid.
SUBSTANCE: three-phase asynchronous engine, operating with power from one-phase power grid, has connection of phase-shifting circuit to phase winding of stator, which provides greatest launching and working torques of subject engine. Therefore, real spatial position of minimal air gap between rotor and stator is taken into consideration. Method for manufacturing aforementioned engines includes switching on in turns of phase-shifting circuit together with every phase winding, measuring of launching(working) torque and selecting additional variant, which provides greatest launching (working) moment.
EFFECT: increased launching and working torques.
