Impact of cross saturation in synchronous reluctance motors of the transverse-laminated type

The cross-saturation phenomenon in synchronous reluctance motors is extensively analyzed, with a main reference to motors of the transverse-laminated type. A mixed theoretical and experimental approach is adopted, aiming at definition of the motor's behavior when large overload currents are driven up to ten times the rated current. As a consequence, a special test and measuring procedure has been adopted. The obtained results are used to check the validity of the adopted model and to prove the unexpected overload performance of this motor.
