G 4. Consider a stepper motor with two phases. Phase 1 is wound with two identical coils. Phase 2 is also wound with two identical coils. Therefore, there are eight wires that come out from the stator winding, four for each phase. (a) Connect the phase terminal wires in such a way that the motor can be used as a unipolar wound motor and draw a schematics for the amplifier circuit of the motor windings. (b) Connect the phase terminal wires in such a way that the motor can be used as a bipolar wound motor with series connected windings (two identical windings for each phase are connected in series). Draw the amplifier circuit and its connections to motor windings. (c) Connect the phase terminal wires in such a way that the motor can be used as a bipolar wound motor with parallel connected windings (two identical windings for each phase are connected in parallel). Draw the amplifier circuit and its connections to motor windings
