电工钢硅钢片Intro of iron core of automobile driving motor。At present, the motor technology of high-speed punching of stator and rotor iron core at home and abroad has developed rapidly. With the development of stamping equipment, new equipment with high quality, high efficiency and high precision has been provided for the production of motor punching pieces of high-speed punching of stator and rotor iron core at home and abroad, which has brought the motor punching process technology. Therefore, the design technology of new technology and equipment suitable for it has become a new research topic. The simultaneous separation of stator punching groove and stator punching groove of motor high-speed punching stator rotor iron core the simultaneous cutting of air gap between rotor punching and rotor punching groove is a new technological scheme applied to high-speed punching machine. This scheme has been widely used in foreign countries and has just begun research and application in domestic motor industry. Therefore, some discussions are made to realize the design technology of this technology according to the required technological equipment.The influence of motor high-speed punching of stator and rotor iron core: the influence of motor punching process technology of motor high-speed punching of stator and rotor iron core in new product development the traditional process of motor punching in our country is two categories: double punching and single punching, which are analyzed as follows:1) the process scheme of double punching groove: this scheme has good groove shape and uniformity, few processes and few tooling, but the tooling is complex and requires high precision, good equipment conditions, long tooling manufacturing cycle and Cheng Bengao, which is only suitable for mass production and is not conducive to new product development and small batch trial production.2) single-type punching process scheme: this scheme has poor groove shape, many processes, many tooling, many equipments, simple tooling, unstable quality, long production cycle and Cheng Bengao, and is only suitable for medium and small batch production.Requirements for high-speed punching of stator and rotor iron core of motor: 1. Positioning accuracy requirements. In this technological scheme, the two composite processes of punching groove separation and punching groove cutting air gap require the same positioning Benchmark, ensuring that the concentricity of the groove shape of the stator and rotor, the outer circular dove tail groove and shaft hole is not more than 0.02mm, the positioning of the center hole meets the technical requirements of concentricity, and the joint positioning of the small side hole and the center hole meets the requirements of circumferential orientation. 2. Precision requirements of composite process. Punching and groove separation compound process: This process has Groove-shaped convex mold and incision convex mold to complete the progressive blanking process. This process first punches and then cuts to separate the fixed and rotor punching pieces. The Two convex molds act synchronously on the same center track, and the central included angle between the two convex molds is one and a half times the central included angle of the groove. This process equipment is applied to high-speed punching machines, the groove-shaped indexing accuracy is guaranteed by the CAM stepping mechanism on the equipment；Electric vehicle is an economical and clean green vehicle based on electric drive,Environment and other aspects have ＊ competitiveness, and can conveniently use modern control technology to realize its electromechanical integration, with broad development prospects.The motor drive system of the iron core of the automobile drive motor is the power source of the electric vehicle, and is the main body and internal basis for determining various performance indexes of the automobile operation. At present, electric vehicle motors mainly include DC motors, induction motors, permanent magnet brushless motors and switched reluctance motors.Automobile drive motor iron core permanent magnet brushless motor can be divided into two categories: one is permanent magnet synchronous motor with sine wave current,The other is the BLDC motor with rectangular pulse wave current.Two kinds of motors, the rotor is magnet, the motor rotor does not need brush and excitation winding, through stator winding commutation to generate rotating torque. Because the rotor has no excitation winding, no copper consumption, small magnetic flux and very small iron consumption at low load, therefore, the permanent magnet brushless motor has a high "Power/mass" ratio and can run at high speed. At the same time, it is easy to cool down because there is no abrasion of the rotor and the stator winding is the main heat source.The characteristics of the iron core of the automobile driving motor； The permanent magnet brushless motor of the iron core of the automobile driving motor has high reliability and high output power. Compared with other motors with the same rotating speed, it has the characteristics of small volume, light weight, easy maintenance, high efficiency, high power factor, etc. The rotor has small electromagnetic time constant and good dynamic characteristics of the motor. Through adjustment and conduction angle, constant power operation can be realized, and the efficiency of the motor can also be optimized by optimizing control angle, thus obtaining wider constant power operation area and higher efficiency.Overview of motor high speed punching stator and rotor iron core
