High Speed Linear Actuator using Halbach Array

A Halbach array is a special arrangement of permanent magnets, forming a strong magnetic field on one side of the magnetic pole i.e. North pole or South pole.

This arrangement of magnet is widely used in application such as Bullet Trains, Particle accelerator, Hyperloop etc..
The most common used in asynchronous motors to increase the Speed & torque values of the motor, for varying load due to voltage & current sources. ex. BLDC motor.

Here, for analyzing the magnetic Array field the arrangement is done with the North or south pole aligned as per the clockwise or anti-clockwise direction forming a 4 -arrow loop & repeats itself for varying length of field/conductor.

The analysis is done using ANSYS Maxwell & AIM solver, to get the magnetic field intensity & the force orientation due to the Halbach array arrangement.
The results are used to build the Linear actuator which is designed to achieve the High speed continuous motion of 0.1 sec for any object with high precession accuracy of 1mm.

This project is further, under development to achieve the linear actuator with high precession accuracy of 1 mm.
