MAGNETIC LEVITATION TRAIN
STUDENTS: TONY PEDERSON & TOBY MILLER
ADVISOR: DR. WINFRED ANAKWA
TABLE OF CONTENTS
The goal of the project is to design a model size train to will be levitated and propelled by electromagnetism. A special magnet array called a Halbach array will be utilized along with a linear synchronous motor to make this train operate.
TRAIN WITH SPEED SENSOR
FREQUENCY REFERENCE SIGNAL FOR SPEED CONTROL
THREE-PHASE POWER INPUT
TRAIN AND TRACK
Halbach Array’s are a special arrangement that cancels the magnetic field above the magnets, but still allows a field below the magnets. The permanent magnets that will be using are made out of Neodymium Iron Boron (NdFeB)
LINEAR SYNCHRONOUS MOTOR
OPTIMUM MAGNET THICKNESS =.2*wavelength (lambda)
Optimum wavelength = 4*pi*y1 (m)
y1 = levitation height (lambda)
Br = (Tesla) remanent field of the permanent magnet
