Motor Magnets: Magnets and assemblies from BESTEN Magnet can be found in many types of motors, generators, and actuators.

Neodymium magnets are widely used in magnetic motor and vehicle magnet applications. Neodymium magnets are typically two to three times stronger than ferrite or ceramic permanent magnets. In electric motors, that results in greater performance from smaller, lighter motors. 


Motor Magnets – Magnetic technology for the motor / VCM market delivers the ability to push the limits on miniaturization, efficiency and performance. Our customers wish to achieve extreme performance in devices such as a wire bonding machines and missile guidance systems. Our customers challenge us to design motors and actuators with features such as:

High force to mass ratio

High speed moving coil designs

Harsh environment withstand capability

The types of motor using permanent magnet such as :

DC motor magnets

Brushless motor magnets

Servo motor magnets

Stepper motor magnets

Linear motor magnets

PM motor magnets

Irregular motor magnets

Automobile motor magnets /Car motor magnets

High performance actuator and motor design requires the use of materials that push the limits of material science. Magnet material selection is critical and we can assist in the selection of the best material. Tradeoffs in the selection include temperature, residual induction, coercivity and environment.

Neodymium Magnets used in Magnetic Motor Applications

Operating temperature: A low coercivity grade Neodymium magnet may begin to lose strength if heated above 176°F (80°C). High coercivity grade Neodymium Magnets have been developed to function at temperatures up to 428°F (220°C) with little irreversible loss. The need for low temperature coefficient in neodymium magnet applications has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade.Ndymium Motor Permanent Magnets for Magnetic Motor Applications

Corrosion: Neodymium magnets are vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles. This vulnerability is addressed by adding a protective coating to prevent exposure to the atmosphere. Nickel plating or two-layered copper-nickel plating are the standard methods, although plating with other metals or polymer and lacquer protective coatings are also available.
