Abstract	Five basic methods of synchronous motor torque measurement are described. The first method is the traditional mechanical measurement using an accelerator; the second method involves an electrical technique using search coils as flux sensors; the remaining techniques employ either terminal voltage and current or input power and speed. Measurements of instantaneous electromagnetic torques of a medium-size 25 HP salient pole synchronous motor using these methods are compared with simulation results obtained from a full-order model as well as with a quasi-linear algebraic approximation. It is shown that torque measurement using search coils in the stator windings gives the best correlation with the simulation results, followed by a modified terminal measurement based on terminal voltage and current. The accelerometer method give the poorest results in that it is unable to capture the low-frequency components of the electromagnetic torques. It is also demonstrated by simulation that the approximate method for calculation of pulsating torques based on a quasi-linear model of the motor gives an estimate comparable to that of the full-order model, particularly for large machines.<>
