The invention relates to the field of motor assembling, in particular to motor synchronous wheel assembling equipment. The motor synchronous wheel assembling equipment comprises a control cabinet anda machine frame arranged on the control cabinet. A motor conveying device and a pressing wheel mechanism which are matched with each other are arranged on the machine frame. A synchronous wheel feeding device matched with the pressing wheel mechanism is arranged on the part, on the machine frame, of the rear side of the pressing wheel mechanism. The motor conveying device, the pressing wheel mechanism and the synchronous wheel feeding device are connected with the control cabinet. A motor is limited through a positioning device of the pressing wheel mechanism, meanwhile, a synchronous wheel ispositioned by the positioning device, the positioning device is pressed by a slow pressing head to drive a motor product on the positioning device to push downwards, the synchronous wheel on the positioning device is arranged on a shaft of the motor in a sleeving mode, and the problem that cracks of the synchronous wheel are caused during press-assembling due to the fact that the synchronous wheel is placed obliquely is solved, so that the motor assembling quality is greatly improved.
