Motors and their associated equipment must be protected against both overload and overcurrent (short circuit or ground fault). This function is usually split, with ...

[Editor’s Note: This is part 2 of a two-part series. For part 1, go to http://bit.ly/gSjOBf.] In the motor control system, current is a common item to be measured ...

Electronic Fuel Injection (EFI) is a solution that guarantees a low emission as well as a fuel consumption optimization, for small motors that, otherwise, can be very polluting. This fact underlines ...

A dynamometer is a testing device that helps engineers collect data for various mechanical loading conditions that a motor or engine might encounter in a particular application. Other than testing the ...

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 ...
