A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetisation.
Halbach linear array combines the radial and parallel arrangement of magnets to form one-sided field, which is an obvious characteristic of Halbach. This feature indicates that Halbach magnet has very good application value in linear motor.

This paper proposes the design of a weighted-rotor energy harvester (WREH) in which the oscillation is caused by the periodic change of the tangential component of gravity, to harvest kinetic energy from a rotating wheel. When a WREH is designed with a suitable characteristic length, the rotor’s natural frequency changes according to the wheel rotation speed and the rotor oscillates at a wide angle and high angular velocity to generate a large amount of power. The magnetic disk is designed according to an optimized circular Halbach array. The optimized circular Halbach array magnetic disk provides the largest induced EMF for different sector-angle ratios for the same magnetic disk volume. This study examined the output voltage and power by considering the constant and accelerating plate-rotation speeds, respectively. This paper discusses the effects of the angular acceleration speed of a rotating wheel corresponding to the dynamic behaviors of a weighted rotor. The average output power is 399 to 535 microwatts at plate-rotation speeds from 300 to 500 rpm, enabling the WREH to be a suitable power source for a tire-pressure monitoring system.

• Custom Magnets. We produce custom magnets with quick and accurate lead time. Custom sizes and grades are available in Bonded or Sintered Neodymium, AlNiCo, Ferrite (Ceramic), Rubberized, and many more materials. We provide design & engineering assistance, and rapid plastic prototypes. If your application consists of a magnet embedded into a plastic or metal part, we can usually produce the entire assembly. If you need large production runs of magnets or assemblies, we can help.
• Licensed Magnets. All magnets bought through Amazing Magnets are guaranteed to be legal. Many neodymium magnet production processes are patented, and neodymium manufacturers are required to pay a license fee in order to legally sell NdFeB magnets (covered by patent protection) in the World.
