Many single-phase motors used with refrigeration-duty, semi-hermetic and hermetic compressors require an external relay to assist in starting. How much do you know about these necessary products? An ...

Due to the wide variety characteristics of the induction motor, it plays the premier role in the industrial sector. Some of those are self starting, rugged construction, high efficiency, good power ...

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

Sometimes the hardest part is getting started. Choose the best motor starting method for a particular application by keeping a few guidelines in mind. For example, while across-the-line starting is ...

Compressor hard-start devices are a luxury item for service technicians to use in rectifying a myriad of compressor start problems. It is true that the majority of hard-start device applications ...

You hop in your Dodge diesel and turn the key only to be greeted with a click-click sound, instead of the more familiar whirring of your starter motor. Something is wrong. You somehow knew that the ...

The project is designed to provide low voltage start to induction motors. This is achieved by using star to delta conversion. Star/Delta starters are probably the most common reduced voltage starters ...
