Abstract: The author defines the electronical commutated DC Motor, which has more commutation units and improved electromagnetic structure, as New DCM, and regards it as a new research field with huge potential. Taking the 9 commutation-units Motor as an example, the basic issues about the designs of New DCM such as armature windings circuit, the installation of position sensor, the logic-transformation discipline of electronically commutation, etc., are discussed in details. The prototype motor is designed and produced, and successfully applied to the electric spindle drive system of the upgraded two-for-one twister product, which has competitive technical-economic index. The case mentioned above has indicated the superiority and development potential of the New DCM. The paper points out that, the New DCM will present more advantage and will explore more widely application prospect, along with its commercialization process.
