The commonly used permanent magnet materials in motors include sintered magnets and bonded magnets, the main types are AlNiCo, ferrite, SmCo, NdFeB, etc.
permanent magnetic materials are widely used in the energy field and have made important contributions to improving energy efficiency.
The number of turns of the coil will have a certain impact on the motor because the winding in the motor is similar to an inductor.
PMSM and synchronous motors are both members of the AC motor family and both use stator windings.
