Traditional processing: the mechanical cutting speed is slow, the noise is big, the chip quantity is large, and the efficiency is low, and the use of the blanking process requires a large number of dies. In the process of processing a product, it usually needs to be equipped with dozens or even hundreds of sets of moulds. The mold itself needs a certain design and manufacturing cycle, and the product also has a certain trial cycle, and the economic cost and benefit are often very low. Cutting laser cutting machine is the energy even to the small space, laser cutting method of non-contact, high speed and high precision by using the high density of energy, is a processing method of laser processing technology is widely used in industrial production. Compared with traditional mechanical cutting, laser cutting has higher cutting accuracy, lower roughness and higher production efficiency. Especially in the field of fine cutting, laser cutting has more advantages than traditional cutting. In the sheet metal operation, laser cutting and blanking are omitted, which greatly reduces production time and product cost. Laser cutting machine has significant cost effectiveness in many kinds of small batch production or later mass production.

Coreless motor is a new type of special motor represents the future direction of motor industry, divided into coreless motor and generator without iron core, the iron core coil, brush, no magnetic damping, rare earth permanent magnet electric technology, has changed the traditional motor using silicon steel plate and the stator winding structure, combined with intelligent electronic frequency conversion technology. The motor system efficiency is increased to more than 95%. No iron core motor has three major technical advantages. First, compared with the traditional radial magnetic field structure design, the axial magnetic field structure is designed, and the power density and the torque volume ratio are greatly improved. The two is to use the new winding process, high pressure precision die casting and polymer materials to effectively reduce the copper loss of winding. The three is that the silicon steel sheet is not used as the stator and rotor core material, which eliminates the magnetic damping and iron loss, reduces the driving power and reduces the heat loss of iron loss. The core less motor power covers 1KW-5500KW, which can be applied to a wide range of fans, pumps, compressors and other general equipment. It can also be used in electric vehicles, wind power generation, CNC machine tools, oil field control units, mobile power plants and other fields. Coreless motor deficiencies: 1, large air gap (usually copper winding, and the air permeability, resulting in almost) required excitation magnetic potential, magnet high cost; 2, 3 winding complex manufacturing process; carbon brush coil, easy to damage, easy maintenance.

Why is the stator core of the DC motor made of a whole piece of steel, while the rotor core is stacked with silicon steel sheets? The magnetic field (main magnetic field) in the stator core is a DC magnetic field with constant size and direction. The flux in the iron core is constant, and the induced electromotive force and eddy current are not produced. The whole steel is made from the aspects of process convenience and magnetic conductivity. Although the main magnetic field size and direction are constant, but the rotor is rotating, the local iron core of the rotor is rotating at different positions of the magnetic field, its flux is alternating, will produce induction electromotive force and eddy current, in order to reduce the eddy current, the rotor core must be laminated with silicon steel sheet.

The commonly used motor core is made of silicon steel sheet. Silicon steel is a silicon containing steel with silicon content ranging from 0.8 to 4.8%. The iron core is composed of silicon steel transformers, because silicon itself is a magnetic material magnetic ability is very strong, in the coil, it can produce large magnetic strength, which can reduce the volume of the transformer. As we know, the actual transformer always works in AC state, the power loss is not only on the resistance of the coil, but also in the iron core under the magnetization of alternating current. Usually the power loss in the core is called "iron loss", the iron loss is caused by two reasons, one is "hysteresis loss", and the other is "eddy current loss"". Hysteresis loss is the iron loss caused by hysteresis in the process of magnetization, which is proportional to the area of the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of the iron core of the transformer is smaller, which can greatly reduce the heating degree of the steel.

Yuyao yuanzhong motor punching co.,ltd, most of the motor stator and rotor lamination such as DC motor stack, AC motor lamination, Servo motor stamping, etc, are produced by high speed punch. . High speed punch is an integrated special cast iron alloy with high rigidity and seismic resistance. The slider is designed with long guide way and equipped with slider balance device to ensure the precision and stability of operation. All wear resistant components are electronic timing automatic lubrication system, such as the lack of lubricating oil, the punch will automatically stop. Advanced and simple control system to ensure the accuracy of slider running and stopping. It can match any automation production requirement, improve production efficiency and reduce cost. High speed punching machine is widely used in precision electronic, communication, computer, household appliances, auto parts, Ma Dading rotor and other small precision parts stamping processing. The design principle of punch is the circular motion into linear motion, by the main motor output, drives the flywheel, clutch driven by gear, crankshaft, connecting rod (or eccentric gear) operation, to achieve the linear motion of the slider, from the main motor to the connecting rod motion to circular motion. A transfer point circular motion and linear motion between a connecting rod and a slide block, the design of roughly two institutions, a ball, a pin type (cylindrical), through this mechanism will transform the circular motion into linear motion of the slider. Punch pressure on the material, the plastic deformation, and the shape and precision required, therefore must match a set of mould (upper die and lower die), the material therebetween, under pressure from the machine, the deformation processing is applied to the material force caused by the reaction.

Motor core, as the core component of the motor, iron core is the non professional terms in the electrical industry, the core is the magnetic core. The magnetic core plays an important role in the whole motor. It is used to increase the magnetic flux of inductance coil, and the maximum conversion of electromagnetic power has been realized. The motor core is usually made up of a stator and a rotor. The iron core plays an important role in the whole motor. It is used to increase the magnetic flux of the inductance coil, and the maximum conversion of the electromagnetic power has been realized. The motor core is usually made up of a stator and a rotor. The stator is usually used as a non rotating part, and the rotor is usually embedded in the stator's internal position. Motor iron core has a wide range of application, stepper motor, AC and DC motor, deceleration motor, external rotor motor, shaded pole motor, synchronous asynchronous motor and so on are more widely used.

How is the motor stator core made? Production process of motor core: 1. Silicon steel slitting 2. High speed punch press silicon steel stator rotor lamination 3. Casting aluminum rotor 4. Die casting 5. Surface treatment 6. Packing The basic requirements of stator core: (1) Good permeability and low loss (2) Good rigidity, good vibration (3) It has good ventilation effect in structure layout (4) The inner diameter and groove size should meet the design precision

Because the motor rotor length is different from the stator length, the magnetic cutting line of the motor is different, which leads to shaft leaping. Minor damage will require a change of bearings, serious damage will cause the motor to burn down. Motor rotor: it is a rotating component in the motor. The motor consists of two parts, rotor and stator. It is used to realize the conversion between electrical energy and mechanical energy, mechanical energy and electrical energy.
