This magnet is a hollow cylindrical/rod magnet made of sintered neodymium material, coated with bright nickel on the surface, with high concentricity and radial magnetization. It is mainly used for hollow cup motors. Different customers have different requirements for the size of the magnet, and the magnetic performance level is usually N42M or higher. It has super strong magnetic energy product and permeability, and can provide strong magnetic fields.
The magnet of a hollow cup motor interacts with the rotor by generating a magnetic field, converting electrical energy into mechanical energy. The selection and arrangement of magnets directly affect the performance of the motor, such as output torque, speed range, and efficiency. Therefore, in the design and application of hollow cup motors, the selection and optimization of magnets are crucial.
