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
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.
The device used to measure the speed of the car is known as speedometer.
Transmission output sensor is usually used as the input sensor for the speedometer, also the braking system uses the wheel speed sensor to determine if a wheel is slowing faster(locking up).
What else can I help you with?
How do you measure the RPM of motor shaft?
you need a tachometer
Can a 2800 rpm motor replace a 1400 rpm motor for air compressor?
No
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.
How can you measure electric motor RPM without a strobe?
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.
How do you reduce rpm of an electric motor from 1200 rpm to 240 rpm?
You would use a worm drive meshed with a gear that has 130 teeth.
How do you measure the RPM of motor shaft?
you need a tachometer
Efficiency of motor?
I measure the efficiency of an internal combustian engine by doing (bhp)/((displacement)*(rpm))
What is acceleration in a three phase motor?
It is a measure of how many rpm the motor gains in one second while running up after being switched on.
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 calculated speed of a four-pole split-phase motor is 1800 RPM. However if you measure the shaft speed you will find it to be 1725 RPM. What causes this loss of rotational speed?
The loss of rotational speed is due to slip in the motor. Slip is a natural characteristic of induction motors and is necessary for torque production. The difference between the synchronous speed (1800 RPM) and actual shaft speed (1725 RPM) represents the slip in the motor.
What is the formula for horsepower?
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.
What RPM can you get out of a 440 cu in motor?
I believe redline is 5,000 RPM.
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.
Can 2800 rpm motor replace 1400 rpm motor for centrifugal water pump?
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.
How do you build an electric motor with over 2000 RPM?
an electric motor can be build with over 2000 rpm,by increasing the supply frequency.
