This paper proposes an analytical approach to reconstruct the air gap torque waveform of an electrical motor from its stator voltages and currents. This approach is consistent with practical implementation requirements of large variable frequency drives, where a direct measurement of the air gap torque is generally not possible. The method is based on an analytical reconstruction of the air gap torque in stationary and orthogonal coordinates. The proposed approach can be used as a design tool… CONTINUE READING
