SUPPORT BOARD FOR ELECTRICAL MACHINE, ELECTRICAL MACHINE AND METHOD OF ITS ASSEMBLY

摘要

FIELD: electricity.SUBSTANCE: support board for electrical machine comprises bearing seat intended for installation of magnet ball bearing designed to rotate rotor of the electrical machine and radial-type outline of the perimeter, whereat three supporting elements are placed. The supporting elements protrude outwards radially to the preset value of protrusion (M) in regard to the perimeter outline so that they determine discrete outline of the perimeter for the support board. The respective values of the supporting elements protrusion (M) are sized so that the support board is aligned when the centre of magnet ball bearing coincides with geometric longitudinal axis of the electrical machine and/or magnetic longitudinal axis of the electrical machine.EFFECT: undesired eccentricity is prevented for the rotor and its vibration.16 cl, 10 dwg
