A motor includes a stator to which a substrate can be stably secured without increasing the size of the substrate. An air-conditioning apparatus includes the motor. At an end portion of the stator in the axial direction thereof, a substrate on which electronic components are mounted is provided. The stator includes: a stator core formed by stacking electromagnetic steel sheets, and including a plurality of teeth; insulators provided on the stator core; and a wire wound around the teeth, the teeth being coated with the insulators. The insulators have outer walls provided on respective core backs of the stator core. In a linearly developed state of the stator, where of the teeth, an outermost tooth is a first tooth, a tooth adjacent to the first tooth is a second tooth, another tooth adjacent to the second tooth is a third tooth, another tooth adjacent to the third tooth is a fourth tooth, and another tooth adjacent to the fourth tooth is a fifth tooth, the outer walls of the first, third and fifth teeth include respective substrate attachment pins for use in attachment of the substrate, and the outer walls of the first tooth include respective power terminals for use in supplying power to the wire.

A method for manufacturing a polymeric electrical machine includes manufacturing a stator including a laminated stator core and a plurality of windings including winding overhangs; applying a surface treatment to the stator core constructed to reduce defects at an interface between a polymeric material and the stator core and enhance adherence between the polymeric material and the stator core; mounting the stator onto a mandrel; inserting the stator into an electrical machine housing mold; molding an electrical machine housing including a stator band with an integral non-drive end endplate, including overmolding the stator and winding overhangs within the stator band; molding a drive end endplate, including forming polymeric ribs in the drive end endplate and overmolding a metallic structure into the endplate, the metallic structure enhancing mechanical stiffness of the endplate; installing a rotor assembly into the electrical machine housing; and installing the endplate onto the electrical machine housing.

A terminal cover includes a cover body equipped with a curved portion and a base portion. The curved portion has formed therein a pair of claws diametrically opposed to each other. The claws are arranged at an interval away from each other. The interval is selected to be smaller than the width of the terminal and increased by elastic deformation of the cover body arising from installation of a terminal in the terminal cover, so that the claws retain the terminal. This structure enables the terminal cover to be simple and small-sized and facilitates installation of the terminal in the terminal cover without being scraped by the terminal when inserted into the terminal cover.

The invention relates to an external rotor device with a rotor housing designed to receive at least one rotor and with at least one sensor magnet provided on the rotor housing. The sensor magnet is arranged/can be arranged in sensory correlation with and in a predefinable relative position relative to the rotor. According to the invention, the external rotor device is characterised in that the external rotor device has at least one ring which is integrally formed on the rotor housing, the ring having at least one pocket which is arranged to receive the sensor magnet, the sensor magnet being arranged/arrangeable in the pocket in such a way and the ring being arranged/arrangeable in a predefinable relative position relative to the rotor on/in the rotor housing in such a way that the relative position of the sensor magnet relative to the rotor in at least one spatial direction is predefined by the materially integral formation, in particular at least with regard to the radial direction and also with regard to the circumferential direction and/or the axial direction.

A motor case has a first case portion and a second case portion coupled to the first case portion. The stator has a stator core and an insulator fixed to the stator core.
