Description

which provides reliable initial self-excitation of the generator.

The presence of longitudinal grooves in the claw-shaped poles of the rotor increases the static stability limit of the machine by increasing the magnetic resistance N, therefore, reducing the value of the inductive resistance along the transverse axis.

The longitudinal grooves of the poles are advisable to have a greater depth than the radial size of the magnets, as shown in FIG. I and 2, which allows a reduction in the flux of magnets shuntable by the rotor magnite lead.

The poles of permanent magnets should be oriented so that they are n. with. was directed against n. with. transverse reaction of the core when the generator is loaded and compensated for it.

As a result, there is no need for a complex construction of fixing in the interpolar space of the rotor of longitudinal magnet magnets having a length approximately equal to the radius of the rotor and experiencing significant centrifugal loads, especially at high rotational frequencies.

At the same time, the presence of longitudinal pazdv in the poles of the rotor with a small relative magnetic permeability of the material installed in the grooves of the permanent magnets increases the limit of static stability of the generator.

Especially effective is the use in the proposed rotor design of permanent magnets with high values of coercion force and magnetic permeability, practically different magnetic permeability of air, for example, permanent magnets based on forriro hard magnetic materials or rare earth elements.
