Design criteria of high performance synchronous reluctance motors

The main problems related to the design of a synchronous reluctance servomotor are examined. The most suitable rotor structure is identified among different alternatives. A simplified but general algorithm is found for calculating the internal optimized anisotropy ratio. Optimization algorithms are given regarding minimization of the q-axis magnetic flux and maximization of torque for given outside diameter and power dissipation capability. A maximum torque design is illustrated in the general case, practical involvements of this design are pointed out and discussed.<>
