Embodiment Construction

[0033] in accordance with figure 1 In the illustrated exemplary embodiment, a two-sided disk rotor motor 1 is shown, which has a rotor 2 between two identically constructed stators 3 , 4 . The rotor 2 and the stators 3 , 4 are aligned parallel to one another and are each spaced apart from one another by an axial gap 5 . like from figure 1 , 2 As can be seen in FIG. 4 , the rotor 2 has a substantially disk shape formed by its carrier disk 6 . Only ferrite magnets 7 , 8 are arranged on the carrier disk 6 in order to form the magnetic poles 9 which form the permanent magnet torque. It is also conceivable that the magnetic poles 9 contribute to the formation of forces, for example for contactless mounting of the rotor 2 , which is not shown in detail.

[0034] In two identically constructed stators 3 and 4, according to figure 1 In each case, a stator yoke 10 is shown, which ends with a plurality of parallel stator teeth 11 . Stator teeth 11 or tooth necks 12 are wound with ...

Abstract

A disc rotor motor is demonstrated, having at least one stator that has at least one electrical stator winding and stator teeth, which have a tooth neck composed of a soft magnetic powder composite, and having at least one disc-shaped rotor, which has permanent magnetic poles composed exclusively of ferrite magnets at least for producing torque, with the rotor and stator oriented parallel to each other and spaced apart from each other by an axial gap. In order to find an optimum between costs, weight, and overall size as well as power and torque density, the invention proposes that the stator teeth each end in a tooth end that adjoins their tooth neck and is composed of a soft magnetic powdered composite, which tooth end widens out in its cross-sectional area in comparison to the tooth neck.

Description

technical field [0001] The invention relates to a disc rotor motor It has at least one stator and at least one disk-shaped rotor, wherein the stator has at least one electrical stator winding and stator teeth, the stator teeth are constructed with a tooth neck made of soft magnetic composite material powder; the rotor has ferrite only The magnets form permanent magnet poles, at least for torque development, wherein the rotor and the stator are aligned parallel to one another and are spaced apart from one another by an axial gap. Background technique [0002] In order to provide a disc rotor motor with reduced material cost, by the prior art (Author: Sone, Kodai, etc., Title: "A Ferrite PM In-Wheel Motor without Rare Earth Materials" Without Rare Earth Materials), IEEE Transactions on Magnetics, 48 ​​(11): 2961-2964) it is known to equip a rotor configured as a rotor disc with only ferrite magnets in order to thereby form permanent magnet poles to create torque. Thus, the...
