Consider the following statements about variable reluctance stepper motor used in control system The static torque acting on rotor is a function of angular misalignment between stator and rotor teethThere are two positions of zero torque i.e, . Q = 0 and where T is the number of rotor teethBoth zero torque positions are stableWhen stator is excited, rotor is pulled into minimum reluctance position Of these statements, the correct ones are

• A. 2, 3, 4
• B. 1, 2, 3
• C. 1, 2, 4
• D. 1, 3, 4
