Abstract
A production method for a rotor core for a VR type resolver has a structure in which one protrusion is formed on an inner edge thereof in which the rotor cores can be rotated and laminated without increasing cost. In a production method of a rotor core for a VR type resolver, a plurality of tabular rotor core pieces are laminated. In this case, in the rotor core pieces, four protrusions are simultaneously formed, one of them is left, the remainder thereof is removed, and rotating lamination is carried out.
