Laboratory centrifuge with electric motor

A laboratory centrifuge has a centrifuge rotor supported on a stator and rotatable on a bearing about an axis of rotation. An electric motor drives the rotor and has pole pieces at a stationary part mounted on the stator and a rotatable part directly attached to the rotor, the stationary part having...

Beschreibung
Zusammenfassung:	A laboratory centrifuge has a centrifuge rotor supported on a stator and rotatable on a bearing about an axis of rotation. An electric motor drives the rotor and has pole pieces at a stationary part mounted on the stator and a rotatable part directly attached to the rotor, the stationary part having pole pieces with drive coils. The pole pieces magnetically act through a gap between the pole pieces and the rotatable part, and the gap lies in a surface which is perpendicular to the axis of rotation or forms a shallow frustocone opening either upwardly or downwardly.
