Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

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 ...

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 ...

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 ...

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 ...

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 ...

In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a custom circuit for them. Join us as we explore the challenges and ...

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 ...
