  • Terminal connection of rotary electromagnetic device
    Patent number: 10938281
    Abstract: A terminal connection of a rotary electromagnetic device and a method of connecting a terminal to an aluminum stator wire of the rotary electromagnetic device without changing stator configuration is described. A de-insulated portion at one of ends of the stator wire is connected to a small connection wire made of copper by ultrasonic welding to form a mutually welded stator wire and connection wire portion. The mutually welded stator wire and connection wire portion are soldered to the terminal to, therefore, form an electric connection between the stator wire and the terminal.
