SOT Regarding Air Compressor


justinevert

Recommended Posts

In my fortress of manhood known as the mancave where Lola sleeps, the motor to my 60 gal. V-Twin compressor has siezed. Looking around for a replacement I see the rpm on new 5 hp single phase 220v 20 amp motors to run either 1,750 or 3,400. Which one is the proper speed?

The motor plate on the old is missing and I am at a loss to which one to choose. Would someone be able to help?

Thanks in advance!!

Justin

The question is not that we broke a few rules or took certain liberties with our female guests.

We did ;)

does you compressor pump have a plate with rpm? You could figure it out from the pulleys then. You might be able to figure it out just by looking at the size of the pulleys and deducing the rpm difference between the two.

Please excuse my ignorance, but as the pump is belt driven it really would not matter. The 3400rpm motor will have double the CFM output to that of the 1750rpm one - you can never have too much air.

The root of why you can't just double the rpm not work is that the motor must have the torque to be able to turn the load (and the compressor pump must be able to handle the rpm too). In electric motors, low torque motors turn at a higher rpm and through gearing (pulleys) you wind up at the same hp and rpm at the pump.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
