Introduction Whether you're in school to become an engineer, fresh out of college or a seasoned veteran of engineering, it's great to have an arsenal of tools at your disposal. Thankfully, we've created a list of our engineer's most loved and used... Keep Reading

Introduction How many times have you heard: "The windows on the school bus are foggy and there's no heat on the bus. My kids are cold!" Clearly, you know there is a problem with the mechanics of the school bus. Unfortunately, you already know the... Keep Reading

Introduction What is decubitus? How can it be prevented among loved ones and patients? These questions and other related topics will be discussed in further detail in the following blog. Learn more about decubitus and preventive treatment, with an... Keep Reading

What's the Difference between Open Loop Blowers and Closed Loop Blowers? What's the difference between open loop control and closed loop control? Simple, it's like driving a car. When you are driving your car, you give the car more gas to go up a... Keep Reading

Use of brushless dc motors is growing faster than that of any other motor type. Their application in blowers is no exception. Among the many benefits these motors offer is the ability to finely control speed — as everything from fixed speed to... Keep Reading

Brushed motors have driven blower, fan, grinder, and vacuum designs for more than 100 years. They remain more relevant than ever as their core strengths — simplicity in control, cost-effectiveness, reliability, and high peak torque outputs — are... Keep Reading

Variable-frequency drives (VFDs) are adjustable-speed ac-motor controls that increase or decrease speed on non-explosion proof motors. Where their inclusion in designs are justified, they boost design performance and efficiency, minimize maintenance... Keep Reading

1. Despite the fact that many in industry use the terms interchangeably, technically there’s a difference between compressors and fans and blowers. Keep Reading

Engineers selecting a blower for a given installation must have detailed knowledge (or at least estimates) of the application’s operating point as well as a plot of the system’s resistance curve; the prospective blower performance in response to... Keep Reading

Consider inrush current and operating current — two values relating to a blower motor’s input capacity and output profile. Inrush current (sometimes called locked-rotor amps or starting inrush, depending on the context) is the current a motor draws... Keep Reading
