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 ( ) consists integrally of a magnet wire binding section ( ) to connect to a magnet wire ( ) of a coil ( ), an external connection section ( ) to connect to an external circuit and a support base section ( ) to press-fit into a terminal block ( ) of a bobbin ( ) and hold the terminal ( ), and the magnet wire ( ) is plasma welded for connection through to the external connection section ( ) (terminal ). The connection of the terminal is carried out by welding (plasma welding), thus the end of the magnet wire of a motor ( ) 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 ( ) press-fits into a hole of the terminal block ( ) of the bobbin ( ), a direction and position of the terminal ( ) are settled to thereby increase the stability.

Terminal structure of a motor

A motor structure having an output shaft with a male screw part mating with a female screw part provided on a rotor rotated by electromagnetic interaction to move the output shaft in an axial direction. The female screw is formed of PPS resin, and the male screw part is formed of metal with a silicon nitride surface layer.
