Abstract: A brushless electric motor with an outer rotor on which permanent magnet elements are arranged, and a stator which has electromagnetic stator poles, wherein the electromagnetic stator poles each have a pole foot, a pole tooth and a pole shoe made of iron materials, and with an insulation layer about the iron elements of the stator poles, and with an electric coil winding which is arranged on the insulation layer, characterized in that the pole shoes have in cross section a free-form rounded portion, preferably in the direction of their end regions, and become narrower running away outward toward the ends at an angle >90° with respect to the pole tooth on the underside of the pole shoe at the location where the insulation layer is applied, wherein the insulation layer on the pole shoe extends on the surface for the coil winding receptacle, that is to say on the basically opposite surface of the insulation layer on the pole shoe, at a right angle with respect to the pole tooth.
Abstract translation: 一种具有永磁体的外转子的无刷电动机和具有电磁定子极的定子，其中，电磁定子极各具有极脚，极齿和由铁材制成的极靴， 围绕定子极的铁元件的绝缘层，以及布置在绝缘层上的电线圈绕组，其特征在于，极靴的横截面为自由形状的圆形部分，优选地在其端部的方向上 并且在施加绝缘层的位置处相对于在极靴的底侧上的极齿以> 90°的角度朝向端部朝向端部变窄，其中极靴上的绝缘层延伸到 线圈绕组容器的表面，也就是说在极靴上的绝缘层的基本相对的表面上，相对于极齿成直角。

Abstract: Pump arrangement (20) for conveying a fluid, with a housing (22), with a first rotatably mounted pump member (24), and with a second rotatably mounted pump member (26), wherein a fluid-conveying effect is produced by means of a relative rotary movement between the first and the second pump member (24, 26), wherein the first pump member (24) can be driven by an electric motor (42) which is arranged concentrically to the first pump member (24) and which has a stator (44) and a rotor (46), wherein the rotor (46) is fixed to the first pump member (24) and wherein the pump arrangement (20) is constructed in such a way that fluid is present in an annular gap (58) between the rotor (46) and the stator (44). In this case, the pump arrangement has temperature control means for heating the fluid in the annular gap (58).
