FIELD: electricity.SUBSTANCE: invention relates to electrical machines, namely to noncontact synchronous generators of inductor type operating mainly with rectifying load, used, for example, in generating units of motor-and-tractor machinery. The inductor machine consists of the front and rear covers, the stator with inducing winding, excitation source, the rotor with shaft; the machine is equipped with two concentrical magnet cores; the inner magnet core is installed in the rotor area and the rotor is placed in the outer magnet core installed in the rear cover and equipped with excitation coil.EFFECT: invention allows on the basis of the initial asynchronous machine by adding of a source of excitation and details of the magnet core obtaining a synchronous inductor electrical machine, which has such a positive feature, that EMF is generated by the rotation speeds of the shaft from low up to rated one, while for operation of asynchronous machine it is required to provide the rotor rotation higher than the rated speed.1 dwg |
