A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Advanced and sophisticated control of all types of motors, and especially brushless DC (BLDC) types, has been receiving lots of attention and support in recent years. This makes sense, as advanced ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

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 ...

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 ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

Racking in or out a power circuit breaker is simple, right? Although this task sounds pretty straightforward in theory, that’s not always the case. In fact, during years of field work related to ...

Genius ideas usually are so simple you start to wonder after seeing them: Why did no one think about this before? This is precisely what we felt after seeing what Infinitum Electric has created: a ...

Faced with ever-increasing cost pressures and demands for improved performance, machine builders are actively seeking new automation solutions with improved cost/performance ratios. In response to ...

Key components of the 1-MW motor. What comprises the 1-MW inverter system? A look at the channel-type heat-exchanger architecture to keep the system cool. Up to a few years ago, “flying cars”—vehicles ...
