The speedometer and speedometer cable tells the driver how fast the vehicle is going. What's called a Hall-Effect sensor is used. It uses the principle of magnetic inductance. When a magnetic flux passes through coils of wire, voltage is generated. To use this effect, a magnet is placed in the cars differential. The sensor then can tell when the magnet comes around by a spike in voltage. Since there is a constant amount the car moves with each differential rotation, and with the time between voltage spikes, you can easily divide to get the speed. This is why changing your cars tires will affect your speedometer. Your car assumes that car moves a certain amount with each differential rotation. If you have larger tires on, then each differential rotation (and axle rotation) your car moves further, and you'll move faster than indicated.

speedometer.
A speedometer or Machmeter.
The instrument that is used to measure speed is called a Speedometer. This may sound obvious, but it is the correct name for the instrument. All motor vehicles by law will have this.
If by 'RPM' you mean 'Revolutions Per Minute,' that would be a 'tachometer.'
A speedometer or Mach-meter is used to measure speed.
With a tachometer.
you need a tachometer
No
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.
Two methods, one uses a dial that is held in the center of the revolving shaft and is directly read off of the dial face. The second method uses a strobe light. The light is focused on the shaft and the dial on the strobe is turned until it looks like the shaft has come to a stand still. The RPM is read off of the meter face of the strobe light.
You would use a worm drive meshed with a gear that has 130 teeth.

I measure the efficiency of an internal combustian engine by doing (bhp)/((displacement)*(rpm))
It is a measure of how many rpm the motor gains in one second while running up after being switched on.
Materials for producing 2900 rpm motor is less than 1450 rpm one
No
Relationship between motor rpm and no of poles
Horsepower = (Torque X RPM) / 5252Horsepower - A measure used to describe a motor's power. 1 horsepower is equal to about 746 watts.Watts - A measure of energy power.
I believe redline is 5,000 RPM.
No. The water pump is designed for a specific RPM. It will not operate correctly, and will probably be damaged, if you attempt to operate it at twice the design RPM.
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.
an electric motor can be build with over 2000 rpm,by increasing the supply frequency.
The formula for RPM is, RPM = Hz x 60 x 2/# of poles the motor has. To answer this question more information needs to be stated.
