This paper presents design analysis and improvement of the proposed high speed hybrid excitation motor (HEM) for main spindle drive in machine tools based on experimental results obtained using prototype motor. The proposed HEM is intentionally designed using 3D-FEA for target application taking into account of practical design constraints. The basic working principle and the unique field weakening...
This paper reports design refinements to make a trial manufacturing of hybrid excitation motor (HEM) for high speed spindle drive in machine tools. The proposed HEM is intentionally designed using 3D-FEA for the target application taking into account of practical design constraints. In accordance with the redesigned specifications, a test machine with 4-pole HEM is manufactured and tested. Some experimental...
