EVALUATION AND OPTIMISATION OF THE TRACK-POLE GEOMETRY FOR A HETEROPOLAR LINEAR SYNCHRONOUS MOTOR (LSM)

The heteropolar linear synchronous motor is being considered at Nottingham for the combined propulsion and levitation of a prototype 3-t vehicle using 4 motors. The motors must accelerate the vehicle at 0.15 g with an airgap of 10 mm. Trapezoidal track poles are shown to be near optimun shape, based on finite difference field plots using the average of zero and infinite permeability boundaries. Design shows the importance of operating at a power factor of about 0.72 (lag) to satisfy the constraints and to reduce motor weight to an acceptable value.
