Here are three merits of the Ward-Leonard speed-control method:

  • It provides very smooth and wide range of speed control from zero to above normal speed in both directions (forward and reverse).
  • It offers excellent speed regulation under varying load conditions, maintaining a stable speed.
  • It allows for regenerative braking, where energy is fed back to the supply during deceleration, improving overall efficiency.
