Magnetic Rotor Assembly

Magnetic Rotor Assembly

Rotor assemblies, one of the most representative magnetic assemblies, are made up of an iron component and a permanent magnet. In reality, depending on the application, motor type, and assembly procedure, bonded magnets, sintered ferrite magnets, sintered Samarium Cobalt magnets, and sintered Neodymium magnets can all be utilized for rotor assemblies. It should be noted that assemblies are also provided with laminated magnets produced via magnet segmentation technology to reduce eddy current loss.

Structure：

The permanent magnet rotor assembly includes a rotor core and a rotor shaft. The rotor shaft passes through the shaft hole of the rotor core and is fastened together with the rotor core. It is characterized in that there are several bosses on the outer side of the rotor core. The magnetic tiles are fastened respectively between two adjacent bosses.

Since the rotor core is provided with several bosses, and the magnetic tile is buckled on the rotor iron core through the boss structure, it can ensure that the magnetic tile and the rotor core are well positioned. In addition, the inner side of the magnetic tile and the The contact surface on the outside of the rotor core is coated with adhesive, which further ensures that the assembly between the rotor core and the magnetic tile is firm and reliable; in addition, there are several through slots on the rotor core, which effectively prevent the rotor shaft from Excellent magnetic conduction and magnetic flux leakage, simple structure, easy assembly and low production cost.

Application：
The magnetic rotor assembly finds application in various industries and devices where the conversion of electrical energy to mechanical energy or vice versa is required. Some common applications of magnetic rotor assemblies include:

1. Electric Motors;
2. Generators;
3. Magnetic Levitation Systems;
4. Magnetic Bearings;
5. Magnetic Couplings: Magnetic rotor assemblies are employed in magnetic couplings, which are used to transmit torque between two rotating shafts without any physical contact. The magnetic field generated by the rotor assembly passes through a non-magnetic barrier, allowing torque transfer while maintaining a hermetic seal. Magnetic couplings are used in pumps, mixers, and other applications where leak-free operation is critical;
6. Magnetic Stirrers: Magnetic rotor assemblies are utilized in laboratory magnetic stirrers. These stirrers use a rotating magnetic field to drive a magnetic stir bar inside a container, facilitating mixing or agitation of liquids or solutions. Magnetic stirrers are commonly used in chemical laboratories, pharmaceutical research, and biological applications.
