A highly integrated comprehensive management platform for the smart manufacturing of electric machines was proposed , the industry of which had been commercialized for long but yet in a phase of transitioning and rapid evolution due to the impact of the 4th industry revolution. With a review of electric machine manufacturing process and investigation of operation of motor manufacturers, suggestions are made on the modelling and system integration of electric machine smart manufacturing. The platform presented was intended for the reference of the development of electric motor digital factory and the optimization of its management.
