This is the method I use.I use 9mm wire and shove the wire against the tabs,using the o ring and plastic ferrule shown below.As the insulator is screwed into the mag plate the ferrule compresses and holds the wire firmly in place.I’ve done this several motors and never had a wire come loose.The plastic ferrule is a 3/8 od plastic pipe insert with a small section cut out so it will fully compress.
