Abstract
The use of an integrated, low cost, non-contact, SAW torque sensor to improve the dynamic performance of permanent magnet servo drive systems has been reported previously. This paper reports on an extension to this research that proposes the use of the SAW device for rotor mechanical position detection. A start-up procedure that enables machine control at and from zero speed is presented.
