NEOMAX® Series Neodymium Magnets / Radially Anisotropic Ring Magnets

NEOMAX® Series Neodymium Magnets, Radially Anisotropic Ring Magnets

DESCRIPTION

At Proterial, we not only support typical block and arc-shaped magnets, but also radially anisotropic ring magnets that have a radial anisotropy direction. These magnets provide a high degree of freedom in setting the number of poles, and can also be magnetized at a skewed angle relative to the axis of rotation (skewed magnetization) to reduce cogging torque (rotation unevenness). They are used in electric power steering (EPS) and exhaust gas recirculation (EGR) systems, which require downsizing and better efficiency, as well as in servo motors for power tools and factory automation.

Radial Anisotropic Magnet

A magnet in which the easy direction of magnetization is radially distributed from the center of the ring cross section.

Multi-pole Anisotropic Magnet

A magnet in which the easy direction of magnetization is controlled in a special distribution so that a magnetic path is formed inside the magnet corresponding to the number of poles in the product.

Features:

<Common>

  1. The cylindrical shape easily ensures dimensional accuracy of the outer diameter facing the stator.
  2. Variations in magnetic flux density distribution between poles are easily reduced because the rotor can be composed of a single magnet.
  3. Easy magnet fixation contributes to reduction of assembly man-hours and integrated molding by resin molding.
  4. The rotor can be composed of a single magnet, which provides high reliability at high speeds, etc.

<Radial anisotropic magnet>

  1. The number of poles can be set arbitrarily, and skew magnetization is possible.

<Multi-pole anisotropic magnet>

  1. A surface flux density close to a sinusoidal wave can be obtained without special magnetization such as skew.
  2. The peak value of the magnetic flux density distribution is higher than that of radial anisotropic magnets.
  3. Since the amount of magnetic flux leakage from the bore side is sufficiently small, non-magnetic materials such as resin can be used for rotor components other than magnets.

Main Applications:

  1. Servo motors for industrial equipment (robots, machine tools, etc.)
  2. Automotive electrical motors (electric power steering, etc.)
  3. Various actuators
