The selection principle of permanent magnet DC motor

The selection principle of permanent magnet DC motor

2022-10-29

Selection principle (1) The choice of type should give priority to ferrite permanent magnet DC motors with high efficiency, low price and low temperature rise. Only when the performance requirements are strict, the size is small, and the ambient temperature is high, consider choosing an AlNiCo permanent magnet DC motor or a rare earth permanent magnet DC motor.

Classification of magnetic materials

Classification of magnetic materials

2022-10-29

Magnetic materials have strong magnetic substances with magnetic ordering, and in a broad sense also include weak magnetic and antiferromagnetic substances that can apply their magnetic properties and magnetic effects.

Characteristics of magnetic materials

Characteristics of magnetic materials

2022-10-29

Materials with ferromagnetic properties have the following characteristics: ① Even if there is no external magnetic field, there is still a magnetic moment in each small area (magnetic domain) inside the material. However, in the absence of an external magnetic field, the direction of the magnetic moment of each magnetic domain is arbitrarily distributed, and the vector sum is zero, so the material as a whole is non-magnetic.
