ABSTRACT:
A method of connecting an end portion of a stator coil of a motor to a terminal, including the steps of locating an insulating plate on one end surface of a stator; positioning the terminal on one side of the insulating plate opposite to the other side where the insulating plate contacts the stator; positioning the end portion of the stator coil on one side of the terminal opposite to the other side where the terminal contacts the insulating plate; pressing the end portion of the stator coil against the terminal with a contact end portion of a source electrode and a first earth electrode which are in contact with each other; contacting a second earth electrode with the terminal from the opposite side of the insulating plate; and supplying a welding current to the source electrode under the conditions that the contact end portion of the source electrode and the first earth electrode are pressed against the terminal and the end portion of the stator coil and that the second earth electrode is in contact with the terminal. With this method, the deformation of the terminal in conducting welding can be prevented, and it is not necessary to define a space for inserting the welding electrodes in the inside of the stator.
