What Are Magnetic Motor Assemblies?

Permanent magnet (PM) motors are one of the most important application areas for permanent magnets. By using permanent magnets for excitation, these motors can reduce power consumption while offering strong efficiency and performance advantages.

The magnetic assemblies used in PM motors are commonly called magnetic motor assemblies.

Magnetic motor assemblies mainly include magnetic rotor assemblies, which are built with permanent magnets together with shafts and cores, and magnetic stator assemblies, which combine permanent magnets with housings or related structural parts. These assemblies work with other motor components to achieve the speed, stability, and torque required for different PM motor designs.

Two Main Types of Magnetic Motor Assemblies

Magnetic motor assemblies are mainly divided into two categories: magnetic rotor assemblies and magnetic stator assemblies.

These two assembly types play different roles in PM motor design and may involve different structures, materials, and assembly considerations. Explore the two categories below to learn more about the related solutions we support.

From Magnet Supply to Assembly Support

Beyond supplying permanent magnets, we also support selected PM motor projects at the assembly level. Depending on the motor structure and project stage, our support may extend to magnetic rotor or stator subassemblies, together with material selection, structural discussion, prototyping, and related engineering coordination.

For certain projects involving controlled rare earth magnet materials, some customers prefer to discuss delivery scope, export licensing requirements, and other project-specific considerations at an earlier stage rather than sourcing magnets alone. This can help define a more suitable delivery scope and project support path from the beginning.

Discuss Your Magnetic Motor Assemblies Project

Whether you are developing a new PM motor design or improving an existing one, early discussion can help define a more suitable support path for the project. SDM can support magnetic motor assemblies projects from magnet supply to selected rotor or stator subassembly work, depending on the application, structure, and project requirements.

If you already have drawings, performance targets, or preliminary assembly concepts, feel free to share them with us for evaluation.
