Halbach Arrays

1. Core Advantages

• Unilateral high magnetic field concentration, extremely low reverse-side magnetic leakage, effectively reduce magnetic interference to peripheral components
• Higher air-gap magnetic flux density, improve motor power density and energy efficiency
• Ultra-low cogging torque & torque ripple, ultra-smooth operation for precision positioning equipment
• Compact & lightweight structure, save installation space for miniaturized automation equipment
• Two mature structural forms: circular ring type for rotary motor, linear flat type for linear motor
• Multiple magnet temperature grades (M/H/SH/UH/EH) optional for different working temperature

Cylinder Halbach Arrays                                               Linear Halbach Arrays:   A Halbach Array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while reducing the field to near zero on the other side. This was achieved by having a spatially rotating of magnetization. High and uniform magnetic field will be produced by Halbach Array in a certain area, and its magnetic field can also exceed the Remanence of the magnetic material itself.
