Explore our top-tier micro coreless motors engineered for low inertia, minimal acoustic noise, and extreme power density.
Unlike standard permanent magnet DC motors that feature a copper-wound slotted iron core, coreless motors (also known as hollow cup motors) utilize a self-supporting skewed winding basket. This unique structural configuration completely eliminates the iron stator core from the rotor loop, leading to fundamental advantages in precision and efficiency.
By eliminating the iron core, we eliminate the physical constraints associated with iron losses, eddy currents, and cogging torque. Cogging is the mechanical hesitation caused by magnetic attraction between the stator poles and rotor slots. In surgical robots, tactile dental instruments, and aerospace optics, even minor cogging can jeopardize operational success. The hollow cup rotor ensures zero-cogging rotation, delivering exceptionally smooth performance at both ultra-low and ultra-high speeds.
Furthermore, because the rotor consists entirely of lightweight copper winding and commutating components, its moment of inertia is extremely small. This guarantees rapid responsiveness—enabling acceleration from zero to peak speeds in a fraction of a millisecond. This ultra-fast dynamic response makes coreless motors ideal for micro-robotics and high-speed precision positioning.
To help system architects choose the correct drivetrain, we outline the fundamental differences between coreless and traditional iron-core motors:
