Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

A synchronous and synchronous motors are the two main categories of ac motors. A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power ...

What consumes more than half of the world's electricity and supports nearly every facet of industrial production? The answer is the AC induction motor. Although these motors typically tolerate ...

Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, now that technology can make it possible and economy ...

When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions. For motor applications, engineers have several ...

Though MOVs are relatively simple devices, choosing the right one requires some knowledge. Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...
