How to choose a magnet for a PM motor
Choosing the right magnet for a permanent magnet (PM) motor is critical for optimizing performance, efficiency, and cost.

A coreless motor is a specialized type of DC electric motor that is designed to be more efficient and responsive than traditional iron-core motors. The key difference lies in the rotor (the rotating part of the motor), which in a coreless motor does not have an iron core. Instead, the rotor windings are typically wound in a self-supporting hollow cylindrical or basket-like structure.
When purchasing magnets, several aspects need to be taken care of to ensure that the magnets purchased meet the specific application needs and quality standards. Here are some key considerations:
Magnetic field lines are abstract concepts used to visualize the distribution and direction of magnetic fields, which are actually invisible.
Maglev technology is utilized across a range of commercial, military and consumer product sectors
Magnets with a 35EH rating refer to a specific classification within the NdFeB magnet series, characterized by their high maximum operating temperature and excellent temperature stability.
The applications of SmCo magent and NdFeB magent, two distinct types of rare earth permanent magnets, vary due to their unique properties.
Designing the magnetic circuit of a permanent magnet motor is a complex process, and multiple factors need to be considered to ensure the performance and efficiency of the magnetic circuit. The following are the general steps and factors to consider when designing the magnetic circuit of a permanent magnet motor:
During the production process of magnets, it is inevitable that some corners or edges will be chipped, especially due to the brittle nature of the rare earth permanent magnet material itself. No matter how meticulous the processing is, some chipped corners will appear. So do the missing corners of these magnets have a big impact on the magnetic properties? Let’s discuss it together.
As for the reasons for motor demagnetization, firstly, the motor cooling fan is abnormal, causing the motor to be high temperature, and the motor is not equipped with a temperature protection device; in addition, the ambient temperature may be too high; and finally, the motor design may be unreasonable.
Why Ndfeb magnet price fluctuates greatly? The main raw materials of NdFeb include rare earths such as praseodymium neodymium, dysprosium iron, terbium metal and pure iron, of which praseodymium neodymium accounts for a large proportion of the price.
How long does the delivery time of Ndfeb magnet take? This is a very specific problem, the delivery date and product performance requirements, specifications, quantity, surface treatment are related, we need to understand the NdFeb magnet production process and processing process, and then to analyze and discuss the delivery time needs how many days?
