Wind Turbine Module Magnetic Assembly During the mounting process of MW-grade Motor/Generator’s magnetic rotor, the NdFeB magnets can be easily damaged during assembly. In this circumstance, the magnet fragment and dust are easily stick and attached to the contact surface between magnet and yoke, which would increase the gap distance and even more, lead to [...]
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. [...]

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 [...]
Fermilab achieves world-record field strength for accelerator magnet To build the next generation of powerful proton accelerators, scientists need the strongest magnets possible to steer particles close to the speed of light around a ring. For a given ring size, the higher the beam's energy, the stronger the accelerator's magnets need to be to keep [...]
Magnetic Badge Holder Attachments Magnetic badge is consist of two parts, the outer part is a nickel-plated steel bar, it is with double-sided foam tape attached. Peel the release paper from the tape, attach it to your name badge, business card, jewelry, or anything else which you plan to attach to your clothing. The inner [...]
Magnetic Theory and Design 1. Can you explain the difference between coercive force and intrinsic coercive force? The intrinsic coercive force is the coercivity of a magnet material in a closed circuit configuration. A closed circuit configuration means the magnet does not have any exposed poles. Some examples of a closed circuit configuration are a [...]
Useful Teacher Magnets in the Classroom As teachers head back to the classroom, a variety of magnets make the grade helping teachers to hold, post, decorate, label, secure and even become the basis of memorable experiments. Taking a page from student supply lists, here’s our recommendation for useful magnets for teachers. 1. Magnetic Pouches: Keeping [...]
Scientists 3D Printed First Ever Permanent Liquid Magnets 3D printed liquid magnets - Scientists at Berkeley Lab have created a new material that is both liquid and magnetic, opening the door to a new area of science in magnetic soft matter. Among other possible applications (such as liquid robots and even 3D entertainment), a 3D [...]
