This sample is an arc-shaped samarium cobalt magnet with characteristics such as high temperature resistance and corrosion resistance, which plays an important role in motors, especially in permanent magnet DC motors and permanent magnet synchronous motors.
In permanent magnet DC motors, curved samarium cobalt magnets are commonly used as permanent magnet excitation sources on the rotor. When the current passes through the stator winding of the motor, the generated magnetic field interacts with the permanent magnetic field on the rotor, resulting in torque. The curved samarium cobalt magnet provides a strong magnetic field, enabling the motor to generate high torque and have good dynamic response and efficiency.
In permanent magnet synchronous motors, curved samarium cobalt magnets are used as permanent magnet excitation sources on the rotor. Similar to permanent magnet DC motors, arc-shaped samarium cobalt magnets generate torque by interacting with the magnetic field generated by the stator winding, driving the motor to operate. Permanent magnet synchronous motors are widely used in industrial and automotive fields due to their excellent power density, high efficiency, and high dynamic response.
