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.

Abstract: The present disclosure provides a robot joint member, a dynamic joint and a robot with a heat dissipation structure. The joint member has a hollow barrel structure disposed to sleeve a heat source component, and a plurality of phase change heat dissipation units; the phase change heat dissipation unit comprises a phase change working medium, a capillary material and a sealed phase change cavity; heat dissipation auxiliary ribs are arranged on a periphery of the barrel wall of the joint member and a side of the phase change heat dissipation unit away from the heat source component; and the heat dissipation auxiliary ribs define a plurality of gas flow channels with cross sections gradually reduced along a gas flow direction. The joint member has can quickly eliminate the heat accumulation of the joint power source, and can keep a compact structure of the dynamic joint of the robot.
