While software and other advanced technologies often capture the automation technology spotlight, the fact remains that not much happens in the manufacturing or processing industries without motors.

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

In Part 1, we saw why we must separate overload protection from fault and short circuit protection for motor circuits. But correctly sizing these different devices can be confusing. And if you follow ...
