STABILISED AXIAL CONTACT-FREE DC GENERATOR Russian patent published in 2012 - IPC H02K11/00 H02K29/00 

FIELD: electricity.

SUBSTANCE: stabilised axial contact-free DC generator comprises a body, a subexciter, an exciter, the main generator and a voltage controller. According to this invention, the voltage controller is installed in the lower part of the generator body and comprises an electromagnet, to the anchor of which a spring is rigidly fixed, and a coal pillar, assembled from a row of coal washers laid onto each other and compressed with a spring. At the same time the working winding of the electromagnet in the voltage controller is connected to the generator outlet, and the coal pillar is included into the circuit of the exciter excitation winding, at the same time resistance of the coal pillar depends on the force of compression of coal washers with the specified spring.

EFFECT: expanded area of application of a generator due to provision of rectified voltage stabilisation.
