Abstract: The present disclosure provides a motor stator and a motor. The motor stator comprises a core; windings wound on the core; and a three-dimensional fitted winding inner groove embedding structure which is a cage-type structure having ribs and ends, the ribs being embedded in grooves between the windings, and the ends being connected to the ribs and cover ends of stator windings; both of the rib and the end of the inner groove embedding structure comprise nonmagnetic heat-conducting glue layers and a phase-change material layer interposed as an interlayer between the heat-conducting glue layers. According to the present disclosure, the heat of each part of the motor stator can be quickly conducted, so as to rapidly reduce the temperature, quickly eliminate the instantaneous temperature peak, and improve the temperature gradient equilibrium of each part.
