When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Symbols and Diagrams for Motors introduces different diagrams used to represent motor circuits and symbols that circuit diagrams commonly contain. Pictorial diagrams are the simplest and use ...

Explains electric current, highlighting that it originates from a battery and requires a complete circuit to flow. It compares electric current to water flowing through pipes, using meters to ...

In order for the solenoid point motor to throw the point we need to apply current briefly to an electromagnetic coil. A capacitor discharge unit greatly improves reliability in that it builds up and ...

When grounding exposed non-current-carrying metal parts of motors and controller frames to prevent a voltage above ground in the event of accidental contact between energized parts and frames, what ...

Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described. A map of brainstem ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
