A part of the motor in simple terms: fixed stator (called定子)And installed on the top of the main pole pairs of dc excitation to stop; And the rotating part (The rotor -rotor)Call the armature iron core, in the above, to furnish the armature winding induction electromotive force, in the aftermath of the electricity act as electromagnetic torque in the aftermath of the rotating magnetic field energy. With built-in method difference in the shape of stator winding, stator winding based on the shape of a coil winding with built-in wiring method is different, can be divided into two categories, centralized and distributed. In simple terms: fixed part of the motor stator (called定子)And installed on the top of the main pole pairs of dc excitation to stop; And the rotating part (The rotor -rotor)Call the armature iron core, in the above, to furnish the armature winding induction electromotive force, in the aftermath of the electricity act as a rotating magnetic field. After the electromagnetic torque of energy conversion. With built-in method difference in the shape of stator winding, stator winding based on the shape of a coil winding with built-in wiring method is different, can be divided into two categories, centralized and distributed. The functions and characteristics of the stator core, stator iron core is commonly used in electronic circuit anti-interference components, have very good inhibitory effect to high frequency noise, the general use of ferrite materials. A lot of people don't know for stator iron core, in order to let you know more about our products, also in order to increase your knowledge, small make up to introduce you to a decision the functions and characteristics of the rotor iron core. 1, the initial high magnetic permeability, low coercive force can reduce the leakage current action of the switch. 2, high saturation magnetic induction intensity, is conducive to choose higher operation point of magnetic induction. 3, the stator iron core high permeability: greatly improve the accuracy of transformer, reduce the contrast. 4, light weight, low cost: the price is significantly better than that of the permalloy. 5, have good resistance to overload capacity and good temperature stability, can be in 55 --130 ℃ homework for a long time. Affect the stator iron core progressive die layout elements of stator iron core as a typical form of high efficiency, high precision, high transient mold, its scale is more and more widely used. Strip layout in the planning the key of success or failure mould and basically concluded that the structure of the whole vice mold, and directly affect the quality of parts produced. In practical production there are many factors of affect stock layout, general progressive die of stator core is summarized as follows: (1)Products structure. It is the most main factors affect the layout. Generally include: (1) of the stator, rotor, deputy shape, size and precision of the stator requirements; (2) the stator pieces is still the core (All needs to fold the riveting is divided into fixed, rotor, a pile of riveting pieces, both pieces)And this will affect the forming process and blanking process planning; (3) whether the rotor demand change, if you need to change, need to consider changing mechanism of bearing, may demand the empty station layout. (2)Layout type. Layout generally choose single row, double row, also has chosen three rows, the utilization ratio of materials bump is one of the main specifications. (3)The mould structure elements. On demand change fold riveting products, should consider to change the space agency, often demand empty station. Pressure plate is generally selected in the motor iron core progressive die to punch and fixed on the fixed plate punch, linking piece through the screw connection, row ignore to consider whether there is enough space linking piece. Core belt is used to derive the discharge method is still the guide cage output, will affect the mould structure. (4)The special requirements of customers. Mainly customers on the basis of itself produces situation demands. Customers to reduce costs, for example, used for blanking of silicon steel sheet material with thickness uniformity of error, the general requirements in the process of riveting stack for 180 g highly public service to ensure that the iron core, this will affect the layout.
