Abstract :
Usually the most significant problem encountered by a reluctance-motor designer is to obtain a motor which will satisfy a prescribed pull-out torque and at the same time pull in a specified load torque and load inertia. He also is faced with the situation that different sizes of stator laminations which he would like to use are already available. With a maximum flux density in the stator teeth and maximum current density in the stator conductors, the designer then would want to obtain systematically for each available size of stator laminations the solution for the following quantities which would constitute the optimum synthesis of the reluctance motor: 1. the ratio of minimum to maximum equivalent air gap, which is actually a measure of the geometry of the machine; 2. the equivalent length of stack; 3. the rotor resistance which, together with the desired starting torque, would make the choice of the number, size, and shape of rotor bars possible; 4. the minimum equivalent air gap; and 5. the number of stator conductors.
