Motor speed is a term we often use to speak to the rotational speed of a motor. And often we talk about the speed of rotation in revolutions per minute, or RPM.

If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
What are units of rotational speed?
The rotation of an object is measured by the unit, rotation/revolutions per second. however, if the speed of a point on the rotating object has to be found, then it can be measured using the standard units of measuring speed.
Do you know what equipment is required to control the speed of motor shaft rotation angle of motor shaft and reverse the direction of motor shaft?
Variable Frequency Drive
What is the process of hybrid cars?
petrol motor gets you up and ging then electric motor maintaind the speed. batteries are charged by the rotation of the wheels
What is the purpose of a motor controller?
A motor controller is a device that controls an electric motor. Most motor controllers require a manual and automatic function, forward and reverse rotation, and speed control.
Number of bolt required to couple the flanges of a coupling depend upon factors?
Depends on motor load transmission, rotation of motor speed, frequency.
What information does a tachometer give you?
A tachometer is an instrument that measures the rotation speed of a shaft or disk, as in a motor or other machine.
What is tach?
A tach (short for tachometer) is an instrument that measures the rotation speed of a shaft or disk, as in a motor or other machine.
Why the DC motor is call as synchronous motor?
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
How do you turn up the forced air fan speed on a central air condition unit?
depends on if you have a 3 speed motor , if not its fixed on speed,
What is asynchronous motor unit?
The regulator that controls the speed at which the sexual organs produce ejaculation.
Application of feedback control system in electrical?
One application of feed back control is where the speed of a motor has to be maintained at a certain RPM and the load it drives is variable. Feedback from the load tells the VFD (Variable Frequency Drive) motor controller what to do. As the load drags the motor speed down the feedback unit sends a electrical impulse to the VFD to increases the speed of the motor. As the load drops off the feedback unit sends a electrical impulse to the VFD to decreases the speed of the motor. These interactions keep the motor RPM at a constant speed. This is a very simplified version of what happens.
