REDUCTION OF SIZE OF THE THRUST BEARING IN VERTICAL MOTORS UTILIZING AXIAL FLUX TECHNOLOGY

摘要

A vertical permanent magnet motor (VPMM) based on axial technology of a single sided structure, using reduced size of thrust bearing, comprising: a shaft (42) disposed within the magnetic frame encompassed by the said thrust bearing at one end and lower guide bearing (44) at other end characterized in that; a rotor which includes the permanent magnet is placed below a stator along the shaft (42) such that magnetic force of attraction over the rotor body and shaft (42) acts in the upward direction.
