In industrial applications, choosing the type of magnet has important implications for motor design, project costs, and overall performance. Therefore, it is important to know that, before making any decision, knowing why NdFeB magnets in a motor may be the right choice.
Having clarified that point, it should be noted that of the four main types of magnets, NdFeB magnets are among the most used in engines for hybrid and electric vehicles. NdFeB magnets have higher remanence, along with higher coercitivity and energy production, but often a lower Curie temperature than other types.
Special alloys have been developed in NdFeB magnets in an engine that includes terbium and dysprosium with a higher Curie temperature, allowing them to tolerate temperatures up to 200 ° C. Because of this, no other magnetic material can match their high-strength performance, so their application in vehicles, for example, has increased considerably.
NdFeB magnets are the strongest magnets in the world. Due to their strength, even small magnets can be effective and this also makes them incredibly versatile. This type of magnet has been used for many purposes and without it, many of the advances in the last 30 years would not have been possible.
The use of NdFeB magnets in a motor, in this case, electric motors, depends on a combination of an electromagnet and a permanent magnet, usually, a NdFeB magnet to convert electrical energy into mechanical energy.
The use of NdFeB magnets in a motor is one of the most promising applications because they include the latest electric and hybrid vehicles, which are often based on rare earth magnets. There are some special reasons available for people to use NdFeB magnets instead of other types of magnets such as ceramic permanent magnets and ferrite.
When it comes to industrial applications, almost all are looking for higher performance with maximum efficiency. For example, when we take electric vehicles, a lightweight, high-performance engine reduces the amount of energy that needs to be transported in the form of hydrogen, gasoline, or batteries.
NdFeB magnets were developed in response to expensive samarium cobalt magnets. At this time, neodymium is considered to be the cheapest and strongest of the earth magnets as a result of these efforts.
