摘要： A terminal of a motor is provided, in which a connection between a coil and an external circuit can be carried out securely and with a good workability, while saving material resources and enhancing safety relating to environmental pollution. A terminal (23) consists integrally of a magnet wire binding section (20) to connect to a magnet wire (4) of a coil (6), an external connection section (21) to connect to an external circuit and a support base section (22) to press-fit into a terminal block (19) of a bobbin (5) and hold the terminal (23), and the magnet wire (4) is plasma welded for connection through to the external connection section (21) (terminal 23). The connection of the terminal is carried out by welding (plasma welding), thus the end of the magnet wire of a motor (1) is connected without using solder containing lead. As a result, since lead is not used, material resources can be saved and safety relating to the environmental pollution can be enhanced. Since the support base section (22) press-fits into a hole of the terminal block (19) of the bobbin (5), a direction and position of the terminal (23) are settled to thereby increase the stability.

摘要： Electromagnetic conversion efficiency of an electric rotary machine is enhanced and reduction of leakage flux due to magnetic discontinuity can be realized without providing holes for positioning and fixing salient poles in a stator ring. Outer appearance and decency of the electric rotary machine as a product are also improved by not allowing lower ends of salient poles of an armature assembly to be exposed on an outer surface of the electric rotary machine. For this purpose a radial gap type electric rotary machine comprises a field magnetic pole consisting of a permanent magnet which is supported rotatably and an armature assembly consisting of a plurality of divided salient poles which oppose the field magnetic pole with a small air gap therebetween and are radially arranged with respect to a rotation axis. The armature assembly includes a first ring made of a soft magnetic member for receiving the plurality of salient poles and a second ring made of a soft magnet member for receiving the first ring.
