This collection includes neodymium arc magnets, rectangular block magnets, and square magnets—each optimized for different motor configurations and prototyping needs.

Neodymium (NdFeB) provides the highest magnetic strength in the smallest size, making it ideal for compact, high-efficiency motors. Ferrite is lower cost but weaker, while SmCo excels in high-temperature environments. Selecting the proper magnet all depends on your specific application. We’re here to help if you need further assistance, contact us.

Most stock motor magnets feature nickel plating for durability and corrosion resistance. Custom coatings (epoxy, Parylene, gold, etc.) are available for specialized applications.

Yes. Neodymium motor magnets are widely used in brushless DC motors, high-torque servo motors, and robotics drive systems due to their superior torque density and reliability.

Yes. We stock select sizes of arc, block, and square motor magnets for rapid prototyping, and their proven strength and durability make them equally reliable for production-scale applications.

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
