Introduction to Hollow Cup Motor Magnets

Hollow cup motors, also known as coreless or ironless motors, are at the forefront of micro-motor technology innovation. These motors differ significantly from conventional motors by utilizing slotless and coreless coils in their armature windings. This design innovation not only revolutionizes the traditional rotor structure but also substantially reduces the motor’s weight and rotational inertia. By eliminating the iron core, these motors drastically reduce the energy losses typically associated with eddy currents. Their low energy consumption, coupled with high sensitivity

Introduction to Axial Flux Motor Magnets

Motors are typically classified based on the orientation of their magnetic flux, with radial and axial flux motors being the predominant types. The axial flux motor, first conceptualized by Michael Faraday in 1821, represents a significant milestone in the evolution of motor technology. Despite its early inception, the axial flux motor’s development was initially overshadowed by the radial flux motor, invented by Tomas Davenport in 1834. This was largely due to the material and technological constraints of the era. Resurgence
