How to install the motor magnet?

As an important internal component of brushless motors, the assembly process of the rotor is crucial, especially the assembly of magnetic steel. Today, we will introduce how to install the motor magnet and some details and precautions for the assembly of motor magnetic steel.Brushless electric motor rotor magnetic steel for electric tools, many require only 4 magnets to be inserted, and can be easily configured with a cylinder, which is relatively simple.Our daily electric vehicles and new energy electric vehicles have relatively complex magnetic steel, which is often distributed around the inner surface. There are many magnetic plates, and if one is not properly inserted, it may affect the performance of the electric vehicle. New energy electric vehicles come in various V-shaped products or other shapes of magnetic steel, with complex design structures and high requirements for magnetic insertion equipment.Whether it is a new installation or a replacement installation, it is important

How to Choose a Magnet Supplier for Customized Injection Molded Magnetic Rotors

Nowadays, various types of motors are applied in various fields such as machines, home appliances, and smart homes, and are also widely used in our daily lives. As one of the indispensable magnet accessories for motors, the demand for injection molded magnetic rotors has greatly increased. As is well known, when developing a new motor product, it is necessary to find a suitable magnet supplier. So, how to choose a supplier for purchasing customized injection molded magnetic rotors for motors?By 2016, due to strict environmental inspections, there was a shortage of magnetic raw materials, which led to an increase in prices and instability. The validity period was sometimes only a few days, or a different price per day. The payment method was also changed from monthly settlement to cash settlement, and payment was made before delivery. This is a serious challenge for magnet factories, and many magnet factories have also been concerned about not receiving orders at the door, which is a vo

How are injection molded magnets made

Injection molded magnets are magnets produced by mixing magnetic powder, resin (PA6, PA8, PA12, PPS, etc.), additives, and other materials using a dedicated injection molding machine through injection molding. The magnetic force of injection molding magnet is slightly lower than that of sintered magnet, but it has the advantages of precise size, light weight, thin wall, complex shape, and stable magnetic properties, which can be bonded and formed with other metal components. In many precision, lightweight, and high-performance electronic products nowadays, injection molded magnets can meet their requirements, which is a difficult condition for sintered magnets to achieve. During the molding process, if an axial or radial external magnetic field is applied to the injection molded magnet, a magnet with higher magnetic properties can be obtained.Mainly used for high-performance micro motors (stepper motors, brushless motors), automotive motors, copiers, laser printers, magnetic sensors, p

Magnet machining is mainly divided into these three types

Magnet mechanical processing is mainly divided into three types, namely cutting processing, shape processing, and drilling processing. Below, we will introduce each of them one by one.Cutting processing: If the magnet is of regular shape, the magnet manufacturer will have a specialized slicing machine. If the magnet is of irregular shape, wire cutting processing must be used;Shape processing: Process circular and square magnets into fan-shaped, tile shaped, slotted, polygonal, or other complex shaped magnets. Shape processing includes grinding slicing, inner circle slicing machine slicing, multi wire cutting slicing, and wire cutting irregular processing.Punching processing: Usually, magnet punching is mainly used to punch countersunk holes, and there are also straight holes. The processing method for countersunk hole circular ring magnets is to cut or drill holes again after slicing, and the processing process requirements are relatively particular.Give a few examples of commonly used

Introduction to Performance Parameters of Multipole Bonded Magnetic Rings for Floor Fan Motors

Regarding this bonded neodymium iron boron D55.85 * d52.85 * 10, some customers have reported a magnetic ring specification of D56 * 53 * 14. Currently, there are various performance and magnetization methods available on the market, and some customers use height 14 and some use height 10. Regarding the magnetization method, there are 8-pole and 10-pole magnets that need to be filled internally. Some magnets require 950gs, while others require 1300gs, depending on the actual usage requirements of the customers.At present, our company has completed its own mold and provided samples for testing regarding the specifications, performance, and surface magnetism of the bonded neodymium iron boron magnetic ring mentioned above. Welcome to inquire!How much is a bonded neodymium iron boron magnetic ring D55.85 * d52.85 * 10?The price of this magnetic ring is approximately 3 yuan per item, and the specific cost depends on your actual needs, payment method, and purchase quantity.If you have custo

How to detect magnets? Inspection items and contents of neodymium iron boron strong magnets

Some customers, before customizing magnets, need to send samples to the magnet manufacturer for testing in order to produce qualified samples due to their own unclear understanding of the material, performance grade, and surface Gaussian of the magnets used by their company.The detection of finished neodymium iron boron magnets generally uses measuring tools such as micrometers, vernier calipers, Gauss gauges, fluxmeters, and film thickness gauges.The film thickness gauge mainly measures the thickness of the electroplating layer of finished neodymium iron boron magnets. The use of a film thickness gauge can effectively monitor the quality of electroplating, and flexible adjustments can be made during magnet electroplating.Micrometers and vernier calipers mainly measure the tolerance and size of magnets, in millimeters.The Gauss meter mainly measures the magnetic force at a point on the surface of a magnet, measured in Gauss. As the magnetic force at each point on the surface of the mag
