The motor lamination stamping machine is a device specially used to manufacture motor cores. Its main function is to cut and stamp silicon steel sheets into a certain shape and size through a stamping process so as to assemble them into the stator or rotor core of the motor.
Working principle of motor lamination stamping machine
Silicon steel sheet raw material preparation:
The motor core is usually composed of multiple layers of silicon steel sheets, which have high magnetic permeability and low loss. These steel sheets are coated with a layer of insulating material to prevent current loss between layers.
Mold design:
The motor lamination stamping machine is usually equipped with specific molds, and the design of these molds is based on the actual structure of the core. The design in the mold includes stamping holes, slots, air holes, etc., which determine the shape and precision of the lamination.
Stamping process:
The motor lamination stamping machine feeds the silicon steel sheet into the mold through a press or hydraulic device, and uses a punch to stamp the steel sheet.
The movement of the punch is usually driven by a motor, which presses the steel sheet down to cut out the iron sheet of the predetermined shape.
During the stamping process, the stamping machine controls the speed, pressure and precision of the stamping to ensure that the shape and size of each lamination meet the requirements.
Multiple stamping:
In order to obtain the final shape of the motor core, multiple stamping operations are usually required. These operations may be to punch out the shape first, and then punch out the holes or slots. By accurately controlling each step of the stamping, it can be ensured that the holes, sizes and shapes of each lamination can match each other and finally be assembled into a high-precision core.
Automatic feeding and discharging:
The motor lamination stamping machine is usually equipped with an automatic feeding system, which can automatically feed the silicon steel sheet into the mold, and at the same time, the stamped iron sheet is sent out through the discharging system, reducing manual operation and improving production efficiency.
Laminated composite core:
The stamped laminations will be stacked into a complete motor core through automatic assembly or manual lamination. Usually, the laminations are fixed by special nails, clamps or insulating materials to ensure good insulation between each lamination.
Summary: The entire process of the motor lamination stamping machine involves precise stamping, layered assembly and automated feeding and discharging operations to ensure that the size and magnetic properties of the final motor core meet the standard requirements.
