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

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

In bypass motors the work is independent from the cooling air. A separate fan directly cools the motor armature and field. Usually the cooling air enters and exists through slots in the equipment housing. Bypass blowers are electric-motor-driven... 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. In short, compressors pressurized gases within controlled volumes to ultimately facilitate some type... 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

Blower performance depends on dozens of electromagnetic and geometric design features. Stack-up of tolerances heightens blower-to-blower performance disparities — even between those supposedly made of identical parts. Keep Reading

Lamb® Electric vacuum motors have been a staple in the commercial market for many years. Whether it’s for scrubbers, extractors or central vacuum systems, these motors are considered critical because of their durability and dependability. Keep Reading

AMETEK Dynamic Fluid Solutions (DFS), the global leader in brushed and brushless blowers/motors and regenerative blower technology, will be exhibiting at THE EXPERIENCE Convention and Trade Show 2019, which takes place this year from September 18-20... Keep Reading

Finding the part you need online can be a cold, confusing experience if you’re not 100 percent sure what you’re looking for. Sifting through webpages and filters is time consuming, and even clunky, just to narrow your search from thousands of SKUs... Keep Reading

In the world of motors, one of the most-used designs is called the universal motor. Basically, these motors are wound-field DC motors, where the armature and field are in series and the current is switched via a commutator and brushes. But what... Keep Reading
