FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Proposed device comprises rotor and stator made as pieces of concentric cylinders from ferromagnetic material. Rotor magnetizing winding is connected to controlled DC source, fixed on stator non-contact to rotor magnet core located in it. In toroidal magnetic gap there is part of operating winding in form of frame from conductor, mechanically connected with controlled drive of its movement inside magnetic gap with measurement of movement value. Outputs of frame are connected to input of direct current amplifier. Closing of "rotor-stator" magnetic circuit is performed by means of cylindrical element of rotor on its opposite end relative to winding of rotor magnetic biasing closely located to tubular magnetic conductor of the stator, which is device housing, in which rotor axis of rotation is fixed through bearing pair, mechanically connected to synchronous motor. On its electric inputs alternating voltage is supplied from controlled frequency AC generator. Data outputs of measuring movement of frame, controlled DC source and controlled frequency AC generator, as well as direct current amplifier output are connected to inputs of processing device and display unit.
EFFECT: technical result consists in possibility of detecting physical structure and behaviour of magnetic field between magnetic poles, one of which rotates relative to each other.
