Can a 2800 rpm motor replace a 1400 rpm motor for air compressor?
No
Which spins faster a two or four blade propeller?
spin rate depends on the RPM of the entire device turning it. If both are turning at the same RPM, they both spin the same speed.
What is the advantage by using 8 pole motor instead of 6 pole motor?
The number of poles in a motor will determine the speed of that motor. n=speed, f=frequency, p=# of poles. n=(120f)/p So a 6 pole motor is rated to operate at n=(120*60)/6=1200 rpm. assuming 60Hz frequency Or a 8 pole motor is rated to operate at 900 rpm. Of course due to slip the rotor will always spin slightly slower.
What is the maximum RPM does a 3 phase motor run at?
The formula for RPM is ; RPM = Hz x (120 (constant)) divided by the # of poles. Number of poles a motor has; # of poles = Hz x (120 (constant)) / RPM.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
Concrete mixer whose motor got following configuration 5.5 KW 380v 1140 RPM 3 phase what is the suitable size of generator to run this motor?
You should get a 3 phase generator that has 8-12 KW. If you had to you could use a 3 phase 5.5-6 kw but it may wear out faster because you are using 100% power. The 3 phase gen will allow you to select 480 volt which can be converted to 380 for the mixer. The rpm of the motor in irrelevant because the generator is the power source in this situation, once the gen powers the motor it will produce 1140 to power the mixer.
Why 2900 rpm motor is less price than 1450 rpm motor?
Materials for producing 2900 rpm motor is less than 1450 rpm one
Can a 2800 rpm motor replace a 1400 rpm motor for air compressor?
No
What is the relationship between motor POLE and RPM?
Relationship between motor rpm and no of poles
What causes the d100 with a v6 to die at a stoplight?
you should raise the rpm of the motor (not too much though) and when at the light, put the car in neutral. this reduces the drivetrain resistance, allowing the motor to spin more freely
How do you calculate the rpm of a motor with a known number of poles and a frequency of 60 Hrtz?
A synchronous motor will spin at the system frequency. 60 Hz translates into 60*60 = 3600 direction changes per minute. If this is a two pole motor (one north and one south), it will spin 1 rotation per direction change. If it is a four pole motor (two north and two south), it will spin 1/2 rotation per direction change. If this is an induction motor, it will spin at a frequency slightly less than an equivalent synchronous motor; this frequency difference is referred to as slip.
How fast would a person have to spin to be knocked out?
figure skater, and circus artist can spin by themself about 360 rpm, so we think they have a 35 cms diameters torso, so they will withstand about 0,40 g per revolution, so if you make a little research over internet you will find the fastest human spin is about 420 rpm, but this is not confirmed, but let supouse that, so is very tolerbale to spin 420 rpm, I think you can spin 500 rpm with no problem, but passing this speed you posibly redout, and explode vessel at eyes, about 700 rpm the blood can damage the brain.
What RPM does a helicopter blade spin at?
Ranges from 250 to 450 rpm.. If there is need to increase the speed then the rpm is eventually increased as per the need
Which spins faster a two or four blade propeller?
spin rate depends on the RPM of the entire device turning it. If both are turning at the same RPM, they both spin the same speed.
What RPM can you get out of a 440 cu in motor?
I believe redline is 5,000 RPM.

How can you determine if an electric motor is 50HZ or 60HZ if there is no name plate?
One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
