The sample is a bread segmented magnet with a height of 30mm, a width of 7mm, and a thickness of 3mm. The material is sintered neodymium, and this shape of magnet is mainly used for motors such as DC motors, stepper motors, and brushless motors. The arc design of this magnet can match the structure of the motor rotor to provide better magnetic field distribution and higher magnetic field strength. This helps to increase the output power and efficiency of the motor, and provides smoother operation.
