The fixed part of the motor is called the stator, on which pairs of DC-excited stationary main magnetic poles are installed; while the rotating part (rotor-rotor) is called the armature core, on which the armature winding is installed. After being energized, an induced electromotive force is generated, which acts as a rotating magnetic field and generates electromagnetic torque for energy conversion. Distinguished by the shape and embedded wiring method of the stator winding, the stator winding can be divided into centralized and distributed types according to the shape of the coil winding and the embedded wiring method.
To put it simply: the fixed part of the motor is called the stator, on which a pair of DC-excited stationary main magnetic poles are installed; and the rotating part (rotor-rotor) is called the armature core, on which a pair of DC-excited stationary main magnetic poles is installed. The armature winding generates an induced electromotive force after being energized, which acts as a rotating magnetic field. It then generates electromagnetic torque for energy conversion. It is distinguished by the shape of the stator winding and the embedded wiring method. The stator winding can be distinguished according to the shape of the coil winding and the embedded wiring method. Divided into two categories: centralized and distributed.
Performance characteristics of stator and rotor coreThe stator and rotor core is a commonly used anti-interference component in electronic circuits. It has a good suppression effect on high-frequency noise and is generally made of ferrite materials. Many people do not know about the stator and rotor cores. In order to let you know more about our products and increase your knowledge, the editor will introduce to you the performance characteristics of the stator and rotor cores.1. Low coercivity and high initial magnetic permeability: can reduce the operating current of the leakage switch.2. High saturation magnetic induction intensity: it is helpful to select a higher working magnetic induction point.3. High magnetic permeability of the stator and rotor core: greatly improves the accuracy of the transformer and reduces the ratio difference.4. Light weight and low cost: the price is obviously better than that of permalloy.5. It has good overload resistance and good temperature stability: it can work for a long time at 55-130℃. Factors affecting stator and rotor core layoutAs a typical mold with high efficiency, high precision and long life, the stator and rotor core progressive mold has an increasingly wide range of applications. Strip layout is the key to the success of mold design. It basically determines the structure of the entire mold and directly affects the production quality of parts. There are many factors that affect strip layout in actual production. Generally, the stator and rotor core progressive molds are summarized as follows:(1) Product structure. It is the most important factor affecting layout . Generally include: ① The shape, size and accuracy requirements of the stator, rotor and auxiliary stator; ② Whether the stator and rotor require loose pieces or iron cores (divided into stator and rotor, both need to be stacked riveted, one stacked riveted and one loose piece, both are loose) (piece), which will affect the design of the forming process and blanking process; ③Whether the rotor needs to be twisted, if so, the position of the twisting mechanism needs to be considered, and an empty station may need to be added during layout.
(2) Layout type. Layout usually uses single row, double row, and sometimes three rows. The material utilization rate is a main criterion for selection.(3) Mold structural factors. For products that require torsion and stack riveting, the space for the torsion mechanism must be considered, and empty workstations often need to be added. In the motor core progressive die, a pressure plate is generally used to fix the punch on the punch fixing plate. The pressure plate is connected by screws. When arranging, it is necessary to consider whether there is enough space for the pressure plate. Whether the iron core discharging method uses a belt or a guide cage will affect the mold structure.(4)Customer’s special requirements. It is mainly based on the requirements put forward by customers based on their own production conditions. For example, in order to reduce costs, when the silicon steel sheet material used for blanking has thickness uniformity errors, the customer usually requires a 180-degree rotation during the stacking riveting process to ensure the core height tolerance, which will affect the layout.
