Summary:The invention discloses a motor commutation device and a processing method, which particularly relate to a large-sized DC motor commutation device and belong to the technical field of motor devices. The device comprises a commutation piece which is arranged on a motor rotor through a sleeve and is provided with a rising piece; two end parts of the commutation piece are equipped with pressing ringmechanisms; insulated mechanisms are arranged between the commutation piece and the pressing ring mechanisms to realize insulated effects; the commutation piece is sleeved with a metal hoop insulatedwith the commutation piece; and the metal hoop is used to enhance the strength of the commutation piece. The problem that the commutation piece in a large-sized DC motor commutation device does not have enough strength and can not reach the standard can be solved; through additionally arranging the metal hoop and combining interference fit, the assembly fastening of the commutation piece is improved thoroughly; and besides
