What is Coreless Motor
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.

Do the missing corners of magnets have a big impact on the magnetic properties?
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.

How to prevent demagnetization of permanent magnet motors
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.
