Effects of uncompensated vector control on synchronous reluctance motor performance

The performance of a synchronous reluctance motor digital controller based on a saturated dq model without compensation for slotting and iron loss influences is investigated. The model predictions for the machine torque characteristics at various speeds including standstill, and the effects of using simplified control strategies are verified by experimental results. Issues related to the low cost software implementation of the control algorithm are discussed. Quality speed control of an axially-laminated machine has been achieved.
