The application relates to the field of electric machines, and discloses a quick-
assembly type
electric machine which comprises a
machine shell, one end of which is provided with an end cover, and the inner side of the end cover is provided with a bearing chamber; a rotor
assembly which has an output shaft rotatably connected between the
machine shell and the bearing chamber, the end of the output shaft away from the bearing chamber extends out of the
machine shell, and the position of the output shaft close to the bearing chamber is provided with a
commutator; a
stator assembly which is arranged in the machine shell and is located outside the rotor assembly; and an
electricity connection unit which comprises a fixing shell, a transmission column, a transmission assembly, an elastic member and an electric
brush, the fixing shell is connected to the inner side of the end cover, the transmission column is movably arranged in the fixing shell along the up-down direction, one end of the transmission column penetrates through the fixing shell and extends out of the end cover, and the transmission assembly is transmissionally connected between the electric
brush and the transmission column; when the
electric machine is assembled, the electric
brush can be driven to move from the outside of the end cover, an avoiding space is provided for the installation of the
commutator, and therefore the quick assembly of the end cover and the machine shell is realized.
