Single phase DC drives

  • Electric drive is a combination of the various system combined together for the purpose of motion control, so it is many more benefits of electric drive to motion control.
  • Some basic features of single-phase DC drives is that speed single output, control fuses fitted,  and it can provide stability adjustment etc.
  • The general circuit arrangement for single phase dc drives as shown in the figure.
  • The arrangement for the speed control of a separately excited for dc motor from single phase source.
  • In this circuit to shown in the figure, it can insert inductor in series with the armature circuit to reduce the ripple in the armature current and also to make the armature current continuous for low values of motor speed to shown in the figure.
