Design of New Type Synchronous Motor Based on the Stability
New type synchronous motor is made of a permanent magnet part and a reluctance part, there are import influence for the motor performance by the variable k, the fraction length of the permanent magnet part, and α, the displaced angle between the two part d-axis. The math model is derived based on Lyapunov stability, searching the appropriate k and α value, plotting stability regions, giving the simulation results. The calculation results are verified by simulation results.
