Calculating the Voltage Drop in An Electrical Circuit is Critical to the Success of Any Electrical Design!

Voltage drop is defined as the amount of voltage loss that occurs through all or part of a circuit due to impedance. Understanding voltage drop is the key to a successful circuit design. A common analogy used to explain voltage, current and voltage drop is a garden hose. Voltage is like the water pressure supplied […]

Bigger Isn’t Always Better When It Comes to Motor Design

Contrary to popular opinion, bigger isn’t always better—especially when it comes to electric motors. Plant maintenance and engineering departments like having a little extra power available “just in case,” so they sometimes specify larger motors than applications require.  But oversized motors cost more to operate—sometimes a lot more. Fortunately, there’s a simple procedure for determining […]

DC Motors are Still Relevant in Today’s Modern Industries

While some may claim that direct-current (DC) motors are no longer relevant, that is definitely not the case. DC motors and DC converters/drives are alive and well in industry, driven by many applications in which they are the best option. Alternating-current (AC) motors have certainly decreased DC motor sales, and they do have advantages in […]
