  • IPM vs SPM Electric Motors

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 [...]

Difference Between Inline and Surface Mount NdFeB Magnets in PM Motors

Difference Between Inline and Surface Mount NdFeB Magnets in PM Motors What is the difference between inline and surface mount design of NdFeB magnets for permanent magnet motors? A permanent magnet (PM) motor is a type of AC motor that uses permanent magnets embedded or attached to the surface of the motor rotor. Electric vehicles [...]

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 [...]

  • Magnetization Dynamics

Magnetization Dynamics

Magnetization Dynamics 1 Introduction Magnetization dynamics, where one investigates the time-dependent motion of the magnetization rather than its equilibrium behavior, are fundamental to the properties of magnetic materials. It is worthwhile remembering that the concept of spin waves was introduced by Bloch  in 1930 in order to calculate the magnetic contribution to the specific heat [...]

Permanent Magnet Magnetic Field Strength

Permanent Magnet Magnetic Field Strength For magnet users, how to confirm the grade and magnetic properties are still a long standing issue. Most of users can’t get the value of main magnetic parameters by themselves. In this case, the relative measurement of magnetic properties is the best solution. The relative measurement of magnetic properties includes [...]
