How to enhance motor performance by optimization of Neodymium Arc Magnet

The vast majority of Neodymium arc magnets are used in applications such as voice coil motor, generators, specific electronic devices and permanent magnet motors. Both shape and structure of the magnet significantly impacts the motor performance as these applications require high tolerance of heat and stress usage. Hence, the practical implementation of the arc magnet must be manufactured to maintain no substantial energy loss during its cycle. One challenge that comes with using arc magnets in permanent magnet motors is the cogging of a slotted motor due to interaction of torque between the magnet and the stator tooth. Due to the Eddy current; also known as Foucault`s current, the temperature rises in the permanent magnet which causes demagnetization hence decreasing the working efficiency of the motor. One solution that worked best to suppress torque ripple, vibration, and noise generated by cogging was to modify the radial flux motor or axial flux motor into a sk

How to distinguish between sintered neodymium magnets and bonded neodymium magnets?

Neodymium magnets are the strongest permanent magnets in the magnet family. It`s grade ranges from N35 to N52, and shape can be customized into round, block, countersunk, arc, cylinder, triangular and so on through various machining process. How do we distinguish between bonded and sintered neodymium magnets? In fact, as both types are made from neodymium magnets, the major difference between bonded and sintered is from the production process. Bonded magnets are manufactured through molding while sintered magnets are produced through vacuuming and high-temperature sintering. Bonded magnets contain binding agents since it is molded and pressed into shape, so its density is only 80% of what it could be in theory. On the other hand, sintered magnets are produced through a more complex process under high temperature, so its magnetic strength is 30% higher than that of bonded magnets. Sintered neody
