Rotor and assembly tool

The rotor comprises a spoke, the spoke is sleeved with an iron core assembly, the iron core assembly comprises a first iron core end plate, an iron core and a second iron core end plate, the first iron core end plate, the iron core and the second iron core end plate are sequentially arranged in the axial direction of the spoke, and the outer wall of the spoke is provided with a first clamping groove concaved inwards in the radial direction of the spoke. A limiting piece is clamped in the first clamping groove and abuts against the first iron core end plate. According to the rotor, the limiting piece is clamped in the first clamping groove to limit the first iron core end plate, and it can be understood that the limiting piece abuts against the side, away from the iron core, of the first iron core end plate, so that the assembly structure of the rotor can be simplified, the assembly procedure of the limiting piece is simplified, and the assembly efficiency is improved. Therefore, the raw material cost and the
