The invention discloses a coupler for an electric bus motor. The coupler comprises a body (1), a flange (2) and a step-shaped through hole. A shaft fastener containing cavity (3) is formed in one end of the through hole, a conical hole (4) with the inner diameter gradually decreasing in the direction from outside to inside is formed in the other end of the through hole, and two key grooves (5) formed in the axial direction are symmetrically formed in the surface of the conical hole (4). The invention further discloses manufacturing process. The coupler for the electric bus motor and the manufacturing process thereof have the advantages that the conical hole structure further improves the coaxiality of a connecting shaft and the coupler, balance performance is good, and the rotating stability of the connecting part is enhanced. A key groove structure further reinforces the coaxiality of the connecting shaft in the conical hole and a connecting shaft fixedly connected with the flange. In the manufacturing proce
