Embodiment Construction

[0030] Fig. 1 is a schematic diagram of an embodiment of a motor according to the present invention. The electric motor has a stator 1 and a rotor 2 that is rotatable relative to the stator 1 and displaceable parallel to the axis of rotation. The stator 1 consists of a stack of soft iron laminations 3 , which form four axially juxtaposed segments 4 . Each segment 4 has a set of permanent magnets 5 distributed around the circumference of the stator 1 , which together form the magnetic means 6 of the stator 1 . The rotor 2 has an iron core 8 with a coil 9 arranged on a shaft 7 and is capable of both linear and rotational vibration movements relative to the stator 1 . In order to excite this vibrational movement, the coil 9 is supplied with a current signal. A magnetic field is formed in particular in the region of the iron core 8 by the current through the coil 9 and the iron core 8 is thus temporarily magnetized. Due to the magnetic interaction between the magnetized iron co...

Abstract

The invention relates to an electric motor for an electrical small-scale unit. Said electric motor comprises at least one oscillatory motor component (1, 2), a magnet arrangement (6) comprising at least one permanent magnet (5), and a coil (9) for producing a magnetic field that generates a force for stimulating a linear oscillatory movement during interaction with the magnetic arrangement (6). The inventive electric motor is characterised in that a torque for stimulating a rotary oscillatory movement is also generated during the interaction of the magnetic field produced by the coil (9) and the magnet arrangement (6).

Description

technical field [0001] The invention relates to a motor for small electric appliances. Furthermore, the invention relates to a small electrical appliance having such an electric motor and to a method for operating the electric motor. Background technique [0002] Motors for small electric appliances are known in various configurations. For example DE 1 151 307 A discloses a vibrating armature drive mechanism for a dry shaver with a shaving cutter capable of reciprocating working movement, which mechanism has a U-shaped electromagnet fixedly connected to the housing of the shaver . A working armature is arranged near the magnetic poles of the electromagnet, and a compensation armature is respectively arranged on both sides of the working armature. In the operating state, the working armature, which drives the shaving cutter, oscillates parallel to the magnetic surface of the electromagnet, wherein the compensation armature vibrates in antiphase to this, in order to prevent...
