Abstract: | In this paper a sensorless closed-loop speed control for the synchronous reluctance motor is presented. The sensorless control is based on the torque vector control algorithm. It has been implemented using a high-speed digital processor DSP96002. Experimental results for a 120 W axially-laminated synchronous reluctance motor are presented and compared with operation with a speed sensor and simulations. A base speed range of 400-1500 RPM has been achieved. The top speed was extended to 2750 RPM using flux-weakening. The drive can be applied a full-load step-change within this speed range without losing synchronism |
