Speed control of any kind of motor is important because it enable the user of the motor to restrain the motor speed to the needed or required speed to accomplish a specific task. omatycoon@gmail.com

∙ 11y agoThe slip is not something that is used to control the speed, it is just the amount by which the motor is running more slowly than the synchronous speed. With a heavier mechanical load on the shaft, the motor runs slightly slower, so the slip increases and the motor draws more current and power from the supply.
Slip is defined by 1-N/N0 where N is the actual speed and N0 is the synchronous speed, and the effective resistance presented to the flow of current is R/s, where R is the resistance of the stator.

What is vf speed control?
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.
Why most of the induction motors have 1440 RPM in India?
To calculate the speed of an induction motor use the following formula, RPM = Hz x 60 x 2/motor # of poles. To answer the question, most of the motors must have 4 poles.
How many types of 3-phase induction motors are there?
One way is to add a capacitor and some extra field windings. Starters are needed because the starting current in an motor may go as high as 6-7 times its rated current. Some of the methods used for starting motors are, Direct online starters, Auto transformers, Soft Starters, Variable Speed Drives, Intelligent Motor Controls.
Why use clutch plate in single phase motor?
induction motors have very little starting torque as the motor come up to speed it reduces the torque load until it gets near synchronous speed
Why variable speed compressor motors are more efficient than single speed motors in heat pump system?
This type of compressor uses a special drive to control The speed of the unit. Also, saves more energy than a fixed speed equivalent.
Why do you control the speed of DC motors?
because dc motor is a powerful & dangerous motor it is akiller

What are convectional and non convectional methods of speed control of a induction motor?
The flux control method is the convectional and the non-convectional method of speed control of an induction motor.

Why is the speed of synchronous motor is more then induction motor?
Synchronous motors run at synchronous speed. An induction motor that has the same number of poles must run at a sub-synchronous speed to create a second magnetic field (a field that is at a different phase angle) to generate torque.
How many Methods can be use to control the speed of Single Phase Induction Motor?
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
