There are many application of motor speed control. Mixer in a food process application needs to run at different speeds. Machine needs to run at different speeds according to required production speed. There are plenty of such application for energy saving etc.

It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.

The speed is varied by throttling the air flow into the motor.
This motor is able to work from the battery. The speed is less complicated to use and you do not need much voltage.
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.
To vary the speed of a permanent magnet synchronous motor, you need to vary the frequency of the AC power source. Of course, this also means you need to vary the voltage because the power factor is going to change, and you need to compensate for that or you might damage the motor.
in some cases we need a desired speed, like in cassette stereo system we need the proper speed so that we can listen the song in a proper manner so we need to control the speed of motor. more example-lift,elevator
slip speed control refers to induction machines s=(synchronous speed-motor speed)/synchronous speed by varying slip the machine can be either be operate in generated mode or motor mode
Ramp up speed in a motor refers to the rate at which the motor accelerates from rest to its operating speed. Ramp down speed is the rate at which the motor decelerates from its operating speed to a stop. These settings are commonly used in motor control systems to control the motor's acceleration and deceleration rates for smoother operation and to reduce stress on the motor and connected equipment.
