This paper presents the bridge design method of rotor of interior permanent magnet (IPM) motor. To optimize torque characteristics of IPM motor, the bridge is one of important factors among design param eters because it affects a mechanical cracking and electrical performa nces. When we design the bridge of IPM motor, a mechanical stress anal ysis should consider a centrifugal force and electromagnetic forces. A total force of above forces is a stress source of the bridge. Electro motive force (EMF), cogging torque, and torque are calculated by finit e element method with Maxwell stress tensor method. The Von Mises criterion is applied to the mechanical stress. As the electroma gnetic forces are considered, the bridge width can be reduced 43% comp ared with the bridge width considering only the centrifugal force.
