Description

Rotor structure of series excited machine Technical Field The utility model relates to the technical field of motors, in particular to a rotor structure of a series excited motor. Background The series excited motor is commonly referred to as a series excited motor, and is named as an exciting winding and an exciting winding are connected in series to work, so that the single-phase series excited motor belongs to an alternating current/direct current dual-purpose motor, and can work by using an alternating current power supply or a direct current power supply. The rotor is one of the important components in a series motor. The existing rotor generally comprises a rotor core and a rotating shaft, wherein a shaft hole is formed in the center of the rotor core, and the rotating shaft is in interference fit in the shaft hole, so that the fixed connection between the rotating shaft and the rotor core is realized. However, when assembling the rotor core with the pivot, generally adopt the press-in method to assemble, too big assembly force can lead to the shaft hole local deformation for the interference of mating surface is inhomogeneous, thereby appears the clearance between pivot and shaft hole, reduces complex compactness, then at motor operation in-process, the pivot can produce not hard up, leads to the assembly insecure, influences the result of use of rotor. Disclosure of utility model The present utility model aims to provide a rotor structure of a series motor for solving the above problems. The rotor structure of the series excited motor comprises a rotor core and a rotating shaft, wherein a shaft hole is formed in the center of the rotor core, a plurality of clamping grooves are formed in the side wall of the shaft hole, a plurality of clamping blocks used for being clamped into the clamping grooves are arranged on the side wall of the rotating shaft, an installation groove communicated with the shaft hole is formed in the rotor core, a sealing cover is detachably connected in the installation groove, and the sealing cover is used for abutting against the clamping blocks to enable the clamping blocks to be fixed in the clamping grooves. As a further arrangement of the utility model, the cover comprises an insert, the side wall of the insert is provided with an external thread structure, and the side wall of the mounting groove is provided with an internal thread structure matched with the external thread structure. As a further arrangement of the utility model, the inner bottom wall of the clamping groove is provided with the elastic block, and the total height of the elastic block and the clamping block is larger than the groove depth of the clamping groove. As a further arrangement of the utility model, the resilient block is made of a rubber material. As a further arrangement of the utility model, the cover also comprises a cover plate arranged on the embedded block, the rotor core is provided with an embedded groove for embedding the cover plate, and the cover plate is provided with a plurality of grooves.
