The structure includes stator and rotor. The stator is composed of stator core, stator winding and base. The stator core is equiangular divided into at least two areas along circumferencial direction. There is a set of integrated three phases winding with independent connection terminal in each area. Thus, failure occurred in a set of stator winding affects only local function, the motor can be running continuously so as to prevent serious damage of relevant system caused by stopping running motor. The invention realizes motor running under malfunction and 'compensation' mode running so as toraise reliability and security.
