Abstract: The present disclosure provides a rotor unit, a rotor, and a motor structure. The rotor unit includes: a rotor punching sheet; a plurality of magnet units comprising a magnet and arranged on the rotor punching sheet; and a hole structure arranged in the magnet. The rotor includes a plurality of rotor units. The motor structure includes: the rotor, a first flow guide plate having a central hole and arranged between two adjacent rotor units, and a central shaft passing through a center of the rotor and the central hole. The present disclosure can effectively reduce the cost of the magnets, and can achieve a direct cooling of the magnets, the rotor and the stator, reduce the eddy current effect, reduce costs, and greatly expand an optimization and use range of the motors when applied in the motors.
