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 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 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 [...]
Permanent Magnet Motor Operation Tips Key technical points for maintaining normal operation of permanent magnet motors Once the permanent magnet motor is demagnetized, basically the only option is to replace the motor; the cost of repair and a large amount of how to determine the permanent magnet motor demagnetized it, we go on to see. [...]
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 [...]
Soft Magnetic Composite SMC Material In recent decades, trends in automotive and other industries have spiked demand for new magnetic materials. As a result, in the mid-1990s the very first components made from soft magnetic composite were born. And the trend of using these soft magnetic composites (SMCs) only continues to grow. Those first SMC [...]
SOFT MAGNETIC POWDER VS LAMINATE MATERIAL for Electric Motor Efficiency Which is easier to trust -- a 1,300-component assembly with shaky performance, or a 10-component one with reliable data? Many manufacturers have worked with the standard, stamped lamination steels for decades. Engineers know the obstacles associated with them, and they accept them as law. But [...]
Permanent Magnets for Electric & Hybrid Vehicle Motors It's hardly surprising that electric and hybrid car' motors differ significantly from typical internal-combustion engines. The rare-earth magnets that help power electric and hybrid vehicles can be rather complex to fabricate, despite having fewer moving parts. We specialize in permanent magnets and their numerous applications here at [...]

Various types of magnets are encased in plated or other surface coated steel cups, channels, plates or customer designed shapes. The magnetized magnet components can create 25 times or more pull force than an individual magnet. VERSATILITY [...]
What is a Magnetic Coupling Magnetic couplings are known by professionals as magnetic drives and are widely used in a variety of general mechanical components. At present, magnetic couplings are used to connect two shafts, namely the motor shaft and the work shaft, and make them rotate together, eventually achieving the effect of transmitting torque.The [...]
Amazing! Bonded NdFeB Magnets are Applied to Permanent Magnet Stepping Motors Permanent magnet stepping motor, also known as PM stepping motor, the rotor uses permanent magnets. The stator of this stepping motor is processed into claw-shaped tooth poles by stamping, and the rotor is made of bonded NdFeB magnets with radial multi-pole magnetization. This kind [...]
