Title:
MAGNETIC ARRAY AND MAGNETIC SUSPENSION PLANAR MOTOR
Document Type and Number:
WIPO Patent Application WO/2015/101156
Kind Code:
A1
Abstract:
Provided are a magnetic array (100) and magnetic suspension planar motor, the magnetic array comprising: one-dimensional Halbach magnetic arrays (120, 130) and two-dimensional Halbach magnetic arrays (110), both forming a square magnetic array, and the two-dimensional Halbach magnetic arrays being respectively disposed on the two ends of a diagonal line in the square magnetic array. The magnetic array employs a combination of one-dimension Halbach magnetic arrays and two-dimension Halbach magnetic arrays, and increases the thrust constant of a magnetic suspension planar motor compared to the magnetic array of the same size employing only one-dimension Halbach magnetic arrays.
