Are rotor embedded magnets the same as surface-mounted magnets? Can they be used for universal devices?

The loading of brushless motor rotor magnets is very important. In the past, it was commonly used to load the magnets manually, but with the coming of the automation era, the automated magnet loading machine became popular and was well received by the customers.

Rotor magnet distribution, common surface distribution, is distributed in the rotor’s inner table or exterior, the magnet is generally uniform distribution of a circle, of course, there are multi-layer distribution; another is embedded magnets, magnets uniformly distributed in the rotor slot, generally have a regular distribution, of course, there are also some shaped distribution.

Are embedded magnets and surface-mounted magnets the same? Can they be used in common equipment?

It can be seen that the distribution of the two types of magnets is different, the structure of the rotor is also different, so the magnet loading method is also different, the equipment used is also different, for the loading of rotor magnets, generally more custom-made equipment, the universality is not good control.

Of course, some rotors with the same outer diameter and different heights can also be used for universal magnet machine, and more than one set of molds can be made.

From the above, we can see that the rotor, whether embedded or surface-mounted magnets, need special equipment, which can improve both production efficiency and quality.
