PMD Mission Statement

“Increase the understanding, promotion and effective utilization of magnetic materials, assemblies and systems for the benefit of the Permanent Magnet Division members and all users of permanent magnet products.”

PMD History

This group was originally founded in 1959 and operated as the Magnetic Materials Producers Association (MMPA). In 2001, PMD became the International Magnetics Association (IMA) and IMA replaced MMPA, expanding its scope and operations in recognition of the global nature of the magnetic industry. In 2007, PMD became a part of SMMA, the motor and motion trade group. In 2015, SMMA merged with the Motion Control & Motor Association (MCMA) – which is now A3 Motion Control & Motors. PMD is now an active part of A3, which supports the work of the PMD and the greater good it brings to the industry.

A Practical Approach To Magnetic Assemblies

Rare earth magnets are becoming increasingly popular for torque coupling and rotors to improve efficiencies, reduce weight and power consumption. The design of the product, proper magnet installation and manufacturing of the final assemblies offer a unique set of challenges. Dangers, safety considerations and best practices are often overlooked until an accident occurs.
