Constructional features

They have several useful properties, including:
(1) combined reluctance and magnet alignment torque;
(2) field-weakening capability;
(3) under-excited operation for most load conditions;
(4) high inductance;
(5) high speed capability; and
(6) high temperature capability.

The synchronous reluctance motor is completely free of magnets and their operational problems. (EE6703 Special Electrical Machines Notes)

It is inexpensive to make, and can operate at extremely high speeds and at higher temperatures than PM motors. However, its power factor and efficiency are not as high as those of a PM motor, and the converter kVA requirement is higher.

The synchronous reluctance motor offers many of the advantages of the switched reluctance motor discussed in Chapter 7, but with the two added advantages that it can operate from essentially standard p.w.m. a.c. inverters and has lower torque ripple. It can also be built with a standard induction-motor stator and winding. (EE6703 Special Electrical Machines Notes)
