A schematic diagram is a drawing that shows physical components in their proper positions within a system, but not necessarily in their actual physical location. Electrical diagrams are the most commonly used drawings. The block diagram, one-line diagram, elementary diagram, and wiring diagram follow an order from very broad to very specific. These diagrams are [...]
The use of prints is the most efficient way to convey information about systems and equipment that cannot be expressed by words alone. By using symbols and notes, a large amount of information […]
There are three types of standard DC motors: series, shunt, and compound (cumulative). The selection of the proper type of motor is based on the type of load that the motor […]
Conveyor belt systems have been responsible for over 80 serious or fatal accidents in the U.S. over the last 20 or so years. According to a report featured by the American Society of Safety Engineers, […]
DC generators are widely used to produce a DC voltage. The amount of voltage produced depends on a variety of factors. A basic DC generator has four basic parts: a magnetic field; a single conductor, or loop; a commutator; and brushes. The magnetic field may be supplied by either a permanent magnet or an electromagnet. [...]
Belt drives for power transmissions are classified as frictional drives since the belt transmits power via friction between the belt and the driving and driven pulleys. Flat belts and V-belts transmit power by their grip on the pulley. The three major factors that determine the potential of grip are […]
In an industrial facility, motors and turbines use energy to produce rotational mechanical motion. In order to harness this motion to perform useful work, there must be a way to transmit […]
