Rotor magnet shaping technologies for permanent magnet electrical machines Engine torque ripple is essential for the comfort of vehicle passengers. Large torque ripple may result in a harsh driving experience. Moreover, additional noise and vibration are byproducts of torque ripple. The service life of the machine and attached components can be influenced by severe vibrations. [...]
Neodymium Radially Magnetized Ring Magnets Neodymium ‘Radially Magnetized’ Ring Magnets have a specific magnetic pattern on either their inside or outside diameter and are most commonly available in three different configurations. A new technology enables the production of super strong, one piece, radially magnetized neodymium ring magnet! Magnets with Skewed Magnetization (show in image 1) [...]
What are the advantages of a radiation (multi-pole) magnetic ring sintered NdFeB The output of sintered NdFeB magnets in China has exceeded 80% of the world's total output. Permanent magnet motors are an important field for the application of rare earth permanent magnets. In recent years, with the development of permanent magnet motor design and [...]
NdFeB MAGNETS Neodymium permanent magnets (Nd-Fe-B / NdFeB MAGNETS) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks, discs and arcs. Attributes of NdFeB Magnets - Very high resistance to demagnetization High [...]
Linear Magnetic Brakes Linear permanent magnet brakes, also known as eddy current brakes, are a fail safe, power free, deceleration system that is used in conjunction with a metal reaction plate. Ceramic or rare earth magnets are bonded to a steel back iron plate. No input power is required. They are used in applications such [...]
Brushless Linear Motors The 3 phase brushless linear motors, also known as a linear servo motors, are direct drive motors that are ideal for long stroke, closed loop servo, linear motion applications. They can be used at speeds up to 240 in / sec [6 m / sec]. They are capable of very precise position, [...]
Understanding the Basics of a Voice Coil Actuator A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor. The name “voice coil” comes from one of its historically first applications: vibrating the paper cone of a loudspeaker. They are currently used for a wide range [...]
Permanent Magnet Generators Offer Improved Performance for RE Production Permanent magnets have been used to provide the magnetic field in small to medium sized generators for many years. The use of these in large renewable energy (RE)generators may offer performance advantages for future utility-scale generators. Large (MW sized) permanent magnet generators (PMGs) are mainly found [...]
What kind of magnet used in linear motor? Linear motor, mainly used in some of the automatic control system, one transmission device converting electrical energy directly into linear motion . Because it is a new and high technology, applied more and more, so the overall prospect is pretty good. A lot of people ask, linear [...]

Permanent magnet vs induction motors The low cost of induction or switched reluctance machines is attracting more and more companies to consider using them for high-speed, high-temperature generating applications. However, their use in such environments will bring about unique challenges and system level disadvantages that will keep permanent magnetic machines the overwhelming preferred choice in [...]
The Uses of Magnets Magnets, besides being fun to play with, have many uses. They are used in consumer as well as industrial goods. Let's get to know more about the uses of magnets. Magnets are materials which produce a magnetic field, and have the capability to attract ferrous components like iron, steel, cobalt, and [...]
