Experimental study of the field in the gap of synchronous machine with the use of sinusoidal turns

The paper deals with experimental study of the gap of a synchronous machine with using sinusoidal turns. The characteristics of a three-phase short circuit and the current dependence of the winding excitation are presented. Static modes of operation of synchronous machines in the stationary state of the rotor by supplying the stator and rotor windings with a direct current conducted by means of sinusoidal and cosine-shaped turns with respect to the transverse axis established in the air gap on the rotor surface along the longitudinal and transverse axes, respectively.
