Abstract: The disclosed embodiments describe a partially caged rotor for use in an interior permanent magnet motor and techniques for fabricating thereof. In some embodiments, a caged rotor includes: a rotor core having a shaft; a rotor cage comprising a plurality of conductor bars; and a plurality of permanent magnets at least partially disposed inside a plurality of mounting holes of the core, the plurality of permanent magnets and the plurality of mounting holes forming a plurality of cavities inside the core; wherein each conductor bar is disposed at a respective cavity of the plurality of cavities such that the plurality of conductor bars is of a number greater or equal to 8 and less or equal to 64.

Abstract: A cell culture insert with a hollow cylindrical housing having an upper end-face opening delimited by an opening edge and a lower end-face base designed as a membrane, support feet being arranged on the base edge of the housing and/or on the base and at least one support arm. The legs protrude downward for supporting the housing on a support in a non-tipping manner with a small uniform spacing between the base and the support. The at least one support arm protrudes outwards at the opening edge and can be placed on an edge of a well plate in which a plurality of wells. The support arm is an edge hanging element, and for this purpose, has a support section that runs radially relative to the housing and a hanging section that runs from the support section downwards in the direction of the base of the housing.
