FIELD: electrical engineering; general-purpose motors. ^ SUBSTANCE: sheet-steel rolled frame of motor has only one welded joint. In order to obtain rigid stator-frame structure eliminating press fit, welded joint is made with frame fitted onto stator, on ends of high-strength rolled frame aligned in a spaced relation to prevent stator deformation. For strengthening welded joint, cover plate is placed on joint and welded to frame. Legs are welded to cover plate to prevent deformation of frame. ^ EFFECT: reduced vibrations during motor running. ^ 1 cl, 2 dwg |
