[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0019] Referring to Figs. 1-3The utility model provides a kind of amorphous stator core for new energy motor, including stator core 1, stator core 1 is made of amorphous synthetic material, stator core 1 includes multiple core laminations 7, multiple core laminations 7 overlap and form stator core 1, the inside center of stator core 1 is provided with rotor support 2, stator core 1 is made of high-performance amorphous synthetic material, core lamination 7 is thin layer amorphous strip, amorphous material has lower hysteresis loss, lower eddy current loss and higher permeability, can significantly improve the efficiency and performance of motor, especially suitable for new energy motor in the application requiring high efficiency and low energy consumption;
[0020] Further, the left and right outer sides of the core laminations 7 are provided with electromagnetic isolation layers, and the outer sides of the electromagnetic isolation layers are coated with ceramic coatings. The thickness of the core laminations 7 is between 10-50 μm. The core laminations 7 are annular, optimizing the magnetic flux path and reducing the edge effect. In order to further reduce the eddy current loss and heat loss, the amorphous stator core can use a special coating or isolation layer, which can effectively prevent the generation of eddy current and enhance the thermal stability. The laminated design of the amorphous stator core is usually more delicate and compact than the traditional silicon steel core, which can effectively reduce the hysteresis loss and eddy current loss. The thin layer design helps to reduce the eddy current loss. By thinning the core, the generation of eddy current can be limited, thereby reducing the loss. Especially in high-speed rotating motors, the overall efficiency of the motor can be improved. The main function of the electromagnetic isolation layer is to reduce electromagnetic interference between the core laminations and prevent the mutual influence of eddy currents between different laminations. The ceramic material has good high-temperature resistance and low thermal conductivity, which helps to improve the working stability of the core at high temperature and slow down the performance degradation or material aging caused by excessive temperature.
[0021] Further, the stator core 1 is provided with multiple winding supports outside. The winding supports are provided with stator windings 3 outside. The material of the stator windings 3 is copper. The stator windings 3 adopt a double-layer winding structure, which helps to reduce harmonics and iron loss, increase the electrical symmetry of the winding, and the rotor support 2 is provided with multiple through holes 4 on the side. The through holes 4 are arranged in an annular array. The inner and outer ends of the winding supports of the stator core 1 are provided with through holes 5 and through holes 6, respectively. The diameter of the through holes 4 is 10 mm. The diameter of the through holes 5 is 14 mm. The diameter of the through holes 6 is 8 mm. Better ventilation and heat dissipation ensure good airflow channels and meet the requirements of fixation or sealing. The smaller diameter of the through holes 4 is suitable for areas with high fixation or sealing requirements, but can provide certain airflow channels to optimize the cooling efficiency of the stator core 1. The diameter of the through holes 5 is relatively large, mainly used to provide larger airflow channels to help speed up the heat dissipation process of the stator windings 3 and the core around, thereby improving the working efficiency of the motor and prolonging the service life. The diameter of the through holes 6 is small, usually used for ventilation and heat dissipation while providing certain sealing performance or preventing external debris from entering the motor interior to maintain the cleanliness of the motor interior.
