The zero and pole designations stem from the fact if we plot the magnitude |Z ( s )| versus s , the resulting curve appears as a tent pitched on the s plane and such that it touches the s plane at the zeros, and its height becomes infinite at the poles. After entering the required data from the nameplate, click on the "Calculate" button to find out the number of poles. Step 2: In this case, zeros are z = 3 and z = 7, cause if you put z = 3 or z = 7, the numerator will be zero, that means the whole transfer function will be zero. Zeros are the values of z for which the transfer function will be zero. In order to find out the synchronous speed roundup the values mentioned on the nameplate to the nearest value in the table below: Speed at 50Hz. the zeros and poles are found by using the cZeros( ) command (screens 20 and 21).
