Taking the motor rotor workshop of an enterprise as the experimental environment and taking the whole process of producing YX3-90L-2 rotor as the object, the process analysis method is used to analyze and record each process flow in the workshop, and simulation research is carried out for the workshop plane layout. A rotor workshop plane layout method is proposed, which saves 2 process flows and shortens the rotor handling distance from 546.10 m to 198.38 m. The transportation time of rotor is shortened from 1 053 s to 736 s, avoiding 5 times of cross transportation. The rotor handling distance and time are reduced, so that the rotor production efficiency as well as the production capacity of the enterprise is improved.
