The invention discloses a power speed change system of coupling driving of dual-motor rotating speed and rotating torque of an electric automobile. The problems that in the prior art, the number of work modes is small, power of a motor is large, a device structure is complicated, and cost is high are solved. According to a dual-motor power coupling speed change system, a main motor is connected with the middle position of an electromagnetic reverser; an auxiliary motor is connected with a left work station of the electromagnetic reverser while being directly connected with a planetary mechanism gear ring; and a right work station of the electromagnetic reverser is directly connected with a planetary mechanism sun wheel. The planetary mechanism gear ring and a box body are connected through a first check bearing, and the sun wheel and the box body are connected through a second check bearing. A planet carrier serves as output and is connected with a second-level dual gear, and a second-stage connection differential mechanism input gear of the dual gear outputs power.
