Electromagnets use electric current to generate a magnetic field which can be turned on or off as needed. They are made from a softer iron which quickly dissipates the induced magnetism after the current is switched off.

  • The Switch to Switched Reluctance
    A quest for energy efficiency has fostered development of switched reluctance motors that are inherently simple and can supply variable speeds. They can be more efficient than induction motors and work at variable speeds. They are also inherently simple. For a time, they powered Switched-reluctance...
  • Linear Motors Offer Precise Positioning and Highly Dynamic Response for Many Motion-Control Task
    motors are simple. Two main components, the primary containing electromagnets and the secondary either with permanent magnets or magnet-free, drive the moving member. This eliminates servomotors, resolvers, tachometers, couplings, pulleys, timing belts, ball screws and nuts, support bearings...
  • Mechanical Switches
    available. Membrane switches are simple devices in which conductive leads on the underside of a flexible membrane are, at a keystroke, pushed through a hole in a spacer to make contact with conductive leads on a base. Most membrane switches handle loads up to about 1.5 VA at 5 to 15 V. Want to use...

  • AC Induction Motor Fundamentals
    AC induction motors are the most common motors used in industrial motion control systems, as well as in main powered home appliances. Simple and rugged design, low-cost, low maintenance and direct connection to an AC power source are the main advantages of AC induction motors. Various types of AC...
  • Basic Types
    Definitions of motion control vary widely in industry today. Depending on the application, motion control can refer to simple on-off control or a sequencing of events, controlling the speed of a motor, moving objects from one point to another, or precisely constraining the speed, acceleration...
  • Clutches
    Driveline components transmit and control power and motion. As simple as this sounds, it is necessary on every machine. Brakes are basically a clutch with one member held stationary. The objective with both classes of hardware is to take two shafts rotating independently at different speeds...
  • Smart Computing Article - How Drives Store Files
    . The principles underlying hard drive technology are fairly simple. Most of us have toyed around with magnets at one time or another. Many people have also seen that a magnet can magnetize material that previously had no magnetic qualities. Now imagine an electromagnet, basically a coil of wire with an electric...
