An electric motor, at least having a stator and an annular rotor which are arranged next to one another along an axial direction; wherein the stator has a plurality of stator teeth which are arranged next to one another along a circumferential direction and which each extend along the axial direction At least one coil has at least one turn is arranged on each stator tooth, wherein the at least one turn is electrically conductively connected to a printed circuit board. The printed circuit board is arranged on an end side of the stator and next to the stator along the axial direction. The printed circuit board comprises a plurality of electrical connecting lines via which the at least one turn of each coil is connected at least to other turns or to an electrical connection of the motor.

Electric motor and printed circuit board

An electric motor, comprising at least a stator, which extends between a first end face and a second end face along an axial direction and has an annular yoke on the first end face and starting from the yoke a plurality of cores, which each extend along the axial direction over a first length to the second end face and are arranged adjacent to one another along a circumferential direction, wherein a coil is arranged on each core, which coil extends starting from the yoke along the axial direction over a second length toward the second end face. The second length is shorter than the first length, so that a portion of each core extends along the axial direction beyond the coil concerned. The motor additionally comprises at least one first rotor which is arranged, at least on the second end face along the axial direction between the coils and the second end face.

Electric motor and method for operating an electric motor

An electric circuit for an electric motor. The electric motor having has at least one stator with at least three coils and a rotor with at least two magnetic poles. The motor is operable by the electric circuit at least in the following two states: a) in a first state, the coils can each be energized with different currents of a three-phase system and the rotor can be set into rotation about an axis of rotation; b) in a second state, the coils can be energized with an in-phase alternating current.

Electric circuit for an electric motor

An electric motor having a rotor with an axis of rotation and an annular stator surrounding the rotor, the stator extending along an axial direction parallel to the axis of rotation and having a first end face and a second end face pointing in opposite axial directions. The stator has exactly two stator teeth extending from an annular circumferential surface that runs between the end faces of the stator, in a radially inward direction to the rotor and facing one another in relation to the axis of rotation, a first stator slot and a second stator slot, which faces the first slot in relation to the axis of rotation, extending along the circumferential surface, between the stator teeth.

Electric motor

A method for operating an electric motor, the electric motor comprising at least one first stator with at least three coils and a rotor with at least two magnets, the first stator and the rotor being adjacently arranged in an axial direction, and the coils being adjacently arranged in a peripheral direction. The electric motor is operated at least in the following two states: a) in a first state, the coils are operated by respectively different phases of a three-phase current, and the rotor is rotated about an axis of rotation; and b) in a second state, the coils are operated by an equal-phase alternating current.
