The invention relates to the technical field of electric drive systems in power transmission, in particular to an eccentric structure electric drive system which comprises an eccentric motor, a connecting gear set and a differential mechanism, the eccentric motor comprises a shell, a rear cover, a controller module, a motor module and a speed reducer module, the controller module is installed in a cavity with the largest diameter, and the motor module is installed in the cavity with the largest diameter. The motor module and the speed reducer module are sequentially installed in the cavity located in the middle, the end of the speed reducer module penetrates through the cavity with the smallest diameter and extends out of the shell, and the differential mechanism is in power connection with the end of the speed reducer module through the connecting gear set. Compared with the prior art, the electric drive system is provided with one shell, two shafts and no connecting wire harness, the structure of the electric drive system is optimized, the number of parts of the electric drive system is reduced, the size of the electric drive system is reduced, and the problems that an existing large-speed-ratio output power system is large in size and high in cost are solved.
