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.

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 ...

When motors start across the line, they typically draw five times the running current. This temporary “inrush” is an overload condition. To handle inrush while still providing adequate overcurrent ...

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 series of three-phase induction motor softstarters prevents motors from experiencing the stress of high inrush currents (typically six to nine times nominal values) that can cause electrical and ...

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 ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Motors are rated by the output power they can produce over a given time period without overheating. These ratings are ...

The fully solid state starters are simple and easy to set up, requiring just two user adjustments: the motor ramp-up time and initial torque, which can be independently adjusted via the built-in ...
