  1. Small-Scale Implementation of Magnetic Levitation Train Nathan Black Ben James Greg Koo Vivek Kumar Preston Rhea Wednesday, April 22, 2009 1

  2. Overview • Objectives: • Levitation • Stabilization • Propulsion • Proof-of-concept • Build awareness • Project cost: $523 2

  3. State-of-the-Art: AMT 4

  4. System Components AC Drive • AC Drive • LSM • Track rails AC Reactor LSM Power Resistors Track Rails

  5. Design Changes – Levitation, Stabilization Track rails with magnets • Magnets spin along one rail • Ball bearings • Spacers • Optimal rail spacing

  6. Design Changes - Propulsion • LSM Windings • 5 wires per phase (18 gauge) to increase magnetic field strength of LSM • Provide uniform propulsion • Train Car • Halbach array 4 disc magnets

  7. Performance – AC Drive Sinusoidal output current desired AC reactor utilized to smooth drive output Peak output current: 10 A Output Voltage: 208Vrms Frequency range used: 2.7 Hz – 5.5 Hz 7

  8. Performance – LSM Secondary Secondary Primary • Lorentz Force I= 10 A, B= 1.2 T, L= 0.0195m • Max Force (single wire) • Force (5 wires) = 0.051*5 = 0.255lbf 8

  9. Performance – LSM Optimal air gap: 2 mm Max air gap: 4 mm Current: 9.1 A Frequency: 5.5 Hz 11
