China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Neodymium magnets (rare-earth permanent magnets) are very popular in motor design, especially in the pursuit of high-efficiency, miniaturized designs due to their high magnetic energy product and high coercive force, etc. The following are some common types of motors that use neodymium magnets.
Permanent magnet synchronous motors (PMSMs) are widely used in electric vehicle drive systems, industrial automation equipment, wind turbines, etc. Neodymium magnets are often used to build permanent magnets in the motor rotor to provide a constant magnetic field.
Brushless DC motors are commonly used in drones, power tools, household appliances, etc. They primarily use high-performance neodymium magnets to increase efficiency and reduce the physical size of the motor.
Servo motors are common in precision control applications such as robotics and CNC machine tools, where neodymium magnets can help achieve high torque density and fast response characteristics.

Linear motors are used in linear motion applications such as high-speed trains, automatic door systems, etc. Neodymium magnets (bars) help achieve high acceleration and smooth motion control.
Commonly used magnet shapes for linear motors: neodymium block bar magnets
Hybrid excitation motors combine the advantages of permanent magnets and electromagnetism to adjust the magnetic field strength, and neodymium magnets are usually used in the permanent magnet section.
Hub motors are mounted directly inside the wheel hub of a vehicle and are used in, for example, electric vehicles. The use of neodymium magnets makes the motor more compact and easier to integrate.
Maglev motors are mainly used in maglev trains and some high-precision instruments. Neodymium magnets are used to provide a strong magnetic field to realize the maglev effect, reduce mechanical friction and improve the stability of the system.
Neodymium magnets are also frequently used in the permanent magnet generator portion of large wind turbines.
Each of these motor types utilizes the powerful magnetic field of neodymium magnets to increase efficiency and reduce size and weight for specific applications. As technology advances, the range of applications for neodymium magnets continues to expand.
