  • DC Controllers
    Dc motors are energized or started by manually operated switches or magnetically operated contactors. Manually operated switches handle a modest range of motor currents. Magnetically operated contactors usually provide a safer and more convenient means for controlling motor power circuits
  • Motor Starters
    : a three-pole starter for the ac stator circuit, a contactor for the dc field circuit, an automatic synchronizing device to control the dc field contactor, and a cage-winding protective relay to open the ac circuit if the motor operates too long without synchronizing. Synchronous motors require ac power
