Abstract
In a manufacturing method of an electric motor, at a time of in-sequence arc welding each of one end of a plurality of lined-up connector terminals to each of a plurality of lined-up detection signal output terminals by a welding rod provided in a torch of an arc welding machine, the method connects each of the other ends corresponding to the respective one end of a plurality of connector terminals to each of earth terminals of the arc welding machine in sequence.
Claims4
A method for arc welding electrical connections between a stator of an electric motor and a plurality of lined up connector terminals coupled to a connector of the electric motor, comprising the steps of:
- connecting an earth connecting device between an earth terminal of an arc welding machine and the connector;
- the earth connecting device provided with a switch terminal operable to selectively interconnect one of the plurality of connector terminals with the earth terminal;
- and
- successively switching the switch terminal between each of the connector terminals and arc welding the connecting terminal then coupled to the earth terminal by a welding rod provided in a torch of the arc welding machine, until each of the connector terminals has been separately arc welded.
