Superconducting Magnetic Levitation and Linear Synchronous Motor Development—The Canadian Program
The Canadian Maglev program has been reviewed previously [1–4]. We are investigating superconducting magnetic levitation, linear synchronous motor (LSM) propulsion, and guidance for 480 km/hr intercity transit along the Toronto-Ottawa-Montreal corridor for the 1990’s. Single 100-passenger vehicles weighing 300 kN are levitated with 15 cm clearance by eight vehicle-borne superconducting magnets (each 1.0 m long × 0.3 m wide, with 3.85 × 105 A turns) interacting with eddy currents induced in 80-cm-wide aluminum strips on an elevated flat-topped guideway. The aluminum strip thickness is graded from 1 cm in high-speed to 3 cm in low-speed sections to maintain total drag (magnetic and aerodynamic) almost speed independent, while minimizing the combined costs of energy requirements and aluminum amortization.
