How much do you know about the servo motor magnetic ring? What is its main function? What kind of magnet material? Where is it usually installed? With everyone's question, led to this paper servo motor multipole magnetic ring function and installation position.
The main function of servo motor multipole magnetic ring;
The main function of the multipole magnetic ring of servo motor is to generate a static magnetic field to control the rotation of the motor. The multipole magnetic ring is usually made of permanent magnet or electromagnet. The more poles it has, the greater the rotational torque it can provide and the lower the rotational speed.
The material of servo motor multipole magnet ring;
Magnetic ring materials usually use high-quality magnetic materials, such as Ndfeb, samarium cobalt, in order to ensure its high magnetic energy product and stable magnetic properties.

Installation position of servo motor multipole magnetic ring;
During the installation of the servo motor, the multi-pole magnetic ring needs to be installed on the rotor of the motor. The specific installation position and method can be determined according to the design and requirements of the specific servo motor.
For permanent magnet servomotors, the multipole magnetic ring is usually attached to the outside of the rotor and can be installed using bolts, glues, or adhesives.
For electromagnetic servomotors, a multipole magnetic ring is usually fixed to the armature, creating a rotating magnetic field in the electromagnet that turns the rotor.
The installation position and method of the multipole magnetic ring may vary for different servomotors of different models and applications. Therefore, it is necessary to understand the specific design requirements of the motor before installation, and then install and debug it correctly. Please be careful when installing and using the servo motor to ensure safety.
