The disclosure relates to an electric machine including a stator having a plurality of teeth and on which a winding of the electric machine is arranged, wherein a respective intermediate space is formed between neighboring teeth. The electric machine further includes a rotor that may rotate relative to the stator, wherein an air gap is formed between the stator and the rotor. The electric machine further includes a plurality of closing devices for closing the respective intermediate spaces in relation to the air gap, and wherein a respective closing device of the plurality of closing devices is arranged between neighboring teeth of the stator.

A rotor for an electric machine is provided. Permanent magnets are disposed on the rotor such that the permanent magnets cannot carry out any tangential movement. The rotor may have four shoulders that extend away from a shell surface of the rotor in a radial direction. Primary permanent magnets that are disposed so as to be mutually contiguous and contiguous to the respective shoulders and accordingly cannot be displaced are in each case located between the shoulders. Secondary permanent magnets are disposed on the shoulders such that an annulus of magnets that is free of gaps and voids and is not movable in the tangential direction is formed.

Rotor for an electric machine

An electric motor equipped with a transmission unit in the form of a planetary gear transmission is provided. The planetary gear transmission has a sun gear, planetary gears, and a ring gear, which are coupled to one another via corresponding toothings. The sun gear is coupled directly to a shaft of the electric motor and is fastened thereto. The planetary gears or axles thereof are retained on a bearing plate of the electric motor. The ring gear is rotatably mounted on the housing of the electric motor or is fastened to the housing of the electric motor. A common feature is that parts of the transmission are retained on the housing of the electric motor and not on a separate housing or another component of the transmission unit.

A separating device has a separating channel, through which a suspension can flow, a ferromagnetic yoke arranged on one side of the separating channel and a separating element arranged at the outlet of the separating channel for separating magnetic or magnetizable particles in the suspension. A plurality of coils arranged along the separating channel are controlled by a control device to produce a magnetic deflection field. The control device produces alternating current directions for controlling neighboring coils.
