Description
技术领域technical field
本发明涉及电磁感应式角度位置传感器技术领域，尤其是涉及一种旋转变压器定子冲片。The invention relates to the technical field of electromagnetic induction angle position sensors, in particular to a rotary transformer stator stamping.
背景技术Background technique
旋转变压器是一种电磁式传感器，又称同步分解器。它是一种测量角度用的小型交流电动机，用来测量旋转物体的转轴角位移和角速度，由定子和转子组成。A resolver is an electromagnetic sensor, also known as a synchronous resolver. It is a small AC motor for measuring angles, used to measure the angular displacement and angular velocity of the rotating object, and consists of a stator and a rotor.
传统旋转变压器冲片设有齿部和槽部，槽部呈梨形槽或圆形槽，底部呈圆形，极靴部靴面线与极身线呈钝角，这样设计的目的更有利于磁力线的流动，降低极靴部磁密，防止极靴部磁密饱和。但实际上旋转变压器为信号元件，工作时磁密最高部分的为极靴部，磁密也仅为毫特级，远低于硅钢片的饱和工作点。这样的结构不仅没有达到防止极靴部磁密饱和的目的，相反还极靴部靴面线与极身线呈钝角、底部呈圆形降低了槽的有效面积，不利于旋转变压器的小型化。The traditional rotary transformer stamping is equipped with teeth and grooves, the grooves are pear-shaped grooves or circular grooves, the bottom is round, and the surface line of the pole shoe and the pole body line form an obtuse angle. The flow of the pole shoe reduces the magnetic density of the pole shoe and prevents the saturation of the magnetic density of the pole shoe. But in fact, the resolver is a signal component, and the part with the highest magnetic density during operation is the pole shoe, and the magnetic density is only milliter level, which is far lower than the saturation operating point of the silicon steel sheet. Such a structure not only fails to prevent the magnetic density saturation of the pole shoe, but on the contrary, the obtuse angle between the surface line of the pole shoe and the pole body line, and the round bottom reduce the effective area of the slot, which is not conducive to the miniaturization of the resolver.
