Dynamic models of electrical machines and their associated drive-train mechanics have had limited experimental validation to-date, due, primarily, to the difficulty in the dynamic measurement of torque. This paper presents results from a study investigating the feasibility of utilising a novel, non-contact, torque measurement system, based on surface acoustic wave (SAW) technology, for application in brushless machine-based, servo drive systems. Simulation of the drive system is facilitated via the implementation of a linear d-q axis induction machine model, coupled with a multi-mass model of the driven mechanical system. Experimental validation of the simulation models is augmented via a test facility comprising of a direct-on-line (DOL) squirrel cage induction machine coupled to an induction generator which provides an electromagnetic and inertial load. The results presented show a good correlation between simulation models and experimental test data previously not acheivable prior to the SAW technology due to the absence of a torque measuring system having suitable bandwidth.
