Description
Solenoids are classified based on the type of Voltage (AC or DC), Action (Linear or Rotational) and Electrical Duty Cycle (EDC). Solenoid consists of a coil wound on a bobbin encapsulated in a frame of suitable size. The bobbin has a through hole in which the plunger operates. When the coil is energized magneto motive force develops, forcing the plunger to minimize the path of magnetic reluctance. While in a Linear Solenoid this motion of the plunger is converted to either the Pull or Push based on the type of end style of the plunger; in case of Rotary Solenoid the motion is rotational. The stroke length and force developed by the pulling or pushing action of the plunger is intelligently used to perform predetermined work (similarly, the angular rotation and the torque of the Rotary Solenoid). These find applications in machineries like textile, pharmaceutical,security,office and robotics.
