  The transformer core is an important part of the transformer, and its quality and performance directly affect the efficiency and stability of the transformer. The following will introduce the process and technology for manufacturing transformer laminations: 1. Raw material preparation: First, silicon steel strips need to be prepared as raw materials for transformer laminations. Silicon steel strip has low magnetic permeability and low loss, which can effectively reduce the eddy current loss of the iron sheet during operation. 2. Cutting: The raw material silicon steel strip needs to be cut accurately according to the design requirements. Equipment such as CNC punch machines or flying shears are usually used to ensure that the cut iron sheets are accurate in size and have smooth edges. 3. Forming: The cut silicon steel strips are formed into iron sheets with specific shapes through lamination and pressing. The molding process needs to control the temperature a

  EI lamination is an important component used to manufacture the core of electric motors. It consists of two parts, the E and I shaped pieces, which are stacked on top of each other to form a complete core. EI lamination is closely related to the power and efficiency of electric motors and therefore plays a key role in the design and manufacture of electric motors. First of all, the design and quality of EI lamination directly affect the core loss of the motor. Core loss is the loss caused by the magnetization of the iron core around the magnet when the motor is running. As the main material of the motor core, EI lamination’s design needs to consider factors such as magnetic flux density, copper loss and eddy current loss to reduce core losses and improve motor efficiency. Secondly, the quality of EI lamination also affects the noise and vibration of the motor. When the motor is running, the iron core generates magnetism, which causes vibration and noise. High
