Abstract： In order to calculate the revolution locus and speed of arcs inside a coaxial plasma generator，a numerical model and method was proposed. The channel model was used to decide the radius of the arc，while the revolution speed of the arc was determined form the mathematical model based on the balance of damping and driving electromagnetic torques of a rigid body using a tabu search algorithm. Numerical results indicate that the trajectory of the plasma arcs in 3D is formed by the rotation of a 2-D parabola locus. Also，the proposed work is validated by the primary tested results．
