FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to the salient pole rotor. Rotor contains a shaft and at least one pole tip. Between the shaft and the pole tip there is a metal sheet. At the same time metal sheet has the first contact surface, which is in contact with contact surface of pole tip. Metal sheet and the pole tip are made from different materials. First contact surface of the metal sheet has a larger surface roughness than the contact surface of the pole tip.
EFFECT: higher reliability.
