Half stepping a stepper motor is achieved by

  • A.doubling the frequency of the pulse train supplied to the driver
  • B.energising one phase and then two phases alternately
  • C.halving the current in every phase throughout
  • D.reversing the direction of one phase at each step

Answer: B

With two phases on, the rotor settles between two full-step positions, so the sequence gives twice as many positions per revolution. The torque alternates between the one-phase and two-phase values, which is a drawback.
