Currently there exist several asynchronous measurement fusion algorithms, namely, firstly strict synchronizing sensors asynchronous data and deal with them with parallel or pseudo-sequential filter.

The paper descirbes several methods for the measurement of the stray loss of thee-phase asynchronous motor, and analyzes the amount of thray loss by using different measuring ways.

It is introduced that series capacitors may arouse self-excitation while online winding resistance measurement of an asynchronous motor.
