A stepping motor has 5 wires a, b, c, d and neutral, where the rotor is a permanent magnet N-S and is the angular displacement between the rotor axis and the stator axis as shown in the figure. The motor is digitally controlled with each winding being in logic 1 if energised and 0 otherwise. For example, the code 0101 corresponds to phases b and d are excited while phases a and c unexcited. a bas cas dog S Neutral Select the incorrect statement among the following choices The code 1000 corresponds to the angle 0 = 0 O To reach the angle of 325 degrees, the digital signal corresponds to the code 1001. O Operating in the half step mode, this motor has a step angle of 45degrees. O With a step angle of 45 degrees, the digital signal applied to the windings will change 8 times in one revolution. O The machine can be digitally controlled by using half a term, i.e., 4 bits. m elet N
