IPM vs SPM Electric Motors

IPM vs SPM Electric Motors A PM motor can be separated into two main categories: surface permanent magnet motors (SPM) and interior permanent magnet motors (IPM) . Neither motor design type contains rotor bars. Both types generate magnetic flux by the permanent magnets affixed to or inside of the rotor. SPM motors have the magnets [...]

Effects of Magnetic Parameters on Permanent Magnet PM Motors

Effects of Magnetic Parameters on Permanent Magnet PM Motors How to measure the magnetic properties of magnet? Almost all magnet manufacturers use B-H curve testing equipment to get the demagnetization curve of magnet. This method is a closed circuit measurement, and an uniform cross-section sample is clamped between the faces of electromagnet. The testing sample [...]

The “Center” of Permanent Magnet Motors

The “Center” of Permanent Magnet Motors – Permanent Magnets The development of permanent magnet motors is closely related to the development of permanent magnet materials. China is the first country in the world to discover the magnetic properties of permanent magnetic materials and apply them to practice. More than 2000 years ago, China made a [...]

  • What is SmFeN Magnet

What is SmFeN Magnet

What is SmFeN Magnet SmFeN magnetic material uses abundant rare-earth Sm element instead of expensive elements of Nd, Dy, Co, etc, and is the most cost-effective rare earth permanent magnetic material. Compared with the bonded neodymium magnet, the bonded SmFeN magnet has higher magnetic properties and lower prices. Moreover, curie temperature, corrosion resistance, and thermal [...]

Permanent Magnets in a Changing World Market

Permanent Magnets in a Changing World Market There are several commercially available permanent magnets. In sequence of invention they are: alnico, ferrite, SmCo (samarium cobalt), NdFeB (neodymium iron boron, Neo), and SmFeN (samarium iron nitride). The last three types are considered “rare earth” magnets because they contain one or more rare earth elements. In terms [...]
