Module 12 Lecture Outline: Introduction to Motion Controls Feedback Devices

  1. Motion Control Parameters
    1. Position
      1. Used in open and closed loop systems
      2. Closed loop: Move load from one fixed position to another fixed position. Feedback is the key to using this control.
      3. Open loop: Position is controlled by an Indexer that provides pulses to a stepper motor. This motor moves in precise, small incremental steps equal to the number of pulses.
    2. Velocity
      1. Motion that takes place with respect to time
      2. Manufacturing applications determine the type of speed that is required to complete the task.
    3. Acceleration
      1. Changes in speed in respect to time
      2. 3 factors are Inertia, Friction, and gravity
    4. Torque
      1. This is the force that causes an object to rotate
      2. Used with motors and hydraulics
  2. Motion Control Elements
