The invention discloses a dual-motor-body stacking motor and a food processer thereof. A large shaft of a first motor body on the upper portion is manufactured to be hollow and sleeves a small shaft of a second motor body on the lower portion, the two motor bodies are connected through a first bearing base and a second bearing base, the coaxiality of the large shaft and the small shaft during rotation can be guaranteed, and the operation noise of the whole motor is reduced; due to independence of the first motor body and the second motor body, according to different performance requirements, the motor bodies can be manufactured to be different in stacking thickness; the two motor bodies can have different rotation speeds and rotation directions, double motor bodies rotate at the same timeor a single motor body rotates, the whole motor is reasonable in structural design, in this way, the manufacturing technology is simple, and the motor is high in applicability and can be applied to various application occasions.
