Abstract: A connection ring terminal. The connection ring terminal is used for connecting to a lead-out end of a connection ring of a motor; and the connection ring terminal comprises a main body and a connection part located at one end of the main body, wherein the connection part is used for surrounding the lead-out end at least in the circumferential direction of the lead-out end, such that the connection ring terminal can be positioned relative to the lead-out end in the radial and circumferential directions of the connection ring. A connection ring and a motor is also provided.

Abstract: A dynamoelectric machine includes a rotor having a rotor core and permanent magnets, and a stator having teeth. The permanent magnets are arranged in magnet sets. Each magnet set includes one or more of the permanent magnets. The rotor core has a cylindrical periphery and slits. Each of the slits is positioned radially between one of the magnet sets and the cylindrical periphery. Each tooth includes a tooth surface facing the cylindrical periphery. The tooth surface includes an inner portion extending substantially parallel to the cylindrical periphery of the rotor core, and beveled portions positioned on opposing sides of the inner portion of the tooth surface. An air gap between each beveled portion of the tooth surface and the cylindrical periphery of the rotor core is greater than an air gap between the inner portion of the tooth surface and the cylindrical periphery of the rotor core.
