Various applications need an electric machine that can provide a wide range of torque over a broad range of rotation speed and temperature. Dynamic testing, where the machine acceleration is compared to the deceleration slope, allows to scan through a wide scope of operation points with insignificant temperature rise. Therefore, the goal of this paper is to analyse the consistency of the rapid experimental evaluation method when comparing the torque derived from the electric input to the one derived from the mechanic output. The paper shows that the electromagnetic torque is estimated within 0.5% expected difference between the two ways of calculating the torque, depending on the selected operation points.
