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 ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...

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 ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system, particularly sags that trip loads.

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 ...

A soft starter has thyristors in its main circuit by which it adjusts motor voltage. Motors that run typical industrial applications employing conveyors, pumps, blowers, and compressors all have one ...

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 ...
