Choose the appropriate motor magnet
Choosing the appropriate motor magnet is a complex process that requires consideration of various factors, including the type, strength, temperature stability, shape, and cost of the magnet. By taking the time to evaluate your specific needs and requirements, you can make wise decisions to help you achieve optimal motor performance.Types of motor magnetsWhen it comes to motor magnets, there are two main types to choose from, namely permanent magnets and electromagnets. Typical permanent magnets are made of materials such as neodymium iron boron permanent magnet, samarium cobalt permanent magnet, and ferrite permanent magnet, which can generate a stable magnetic field without any external power supply. On the other hand, electromagnets are made by winding a coil around a ferromagnetic core, which requires an electric current to generate a magnetic field.Temperature stability of motor magnetThe temperature stability of magnets is another important factor to consider, as it can affect the
