What are the disadvantages of a three phase induction motor?

The primary disadvantage of the three phase induction motor is that speed control is a challenge. But new technology in the form of VFDs (variable speed drives) is now rectifying this situation very effectively. Another disadvantage is that single phase power is common while three phase power is less commonly available.


why we use variable speed drivers in motor control units?

Variable speed drivers are necessary to be able to have different speed settings in a motor.


Why variable voltage and variable frequency control is used instead of variable voltage?

variable voltage control has some limitations as you decrease the voltage corresponding phase current will increase lead to increase of flux which lead to saturation of motor core and heating of motor to make flux constant and vary speed of motor v/f ratio need to be maintained constant


What is the function of vfd?

It is a variable frequency drive, used to control the speed of a 3-phase motor all the way from stopped to full speed, and anywhere in between. Also called VSD, for variable speed drive, they are used to control pumps, fans, conveyor belt drives, anywhere a motor needs to be controlled to a precise speed other than the normal nameplate full speed, or where the speed needs to change to meet different operating conditions.


How do you reduce the speed of a single phase digital meter 1600mp or kWh 50HZ without reducing the consumer load?

The speed of a single phase digital meter 1600mp or kWh 50HZ can be reduced. By decreasing the voltage to reduce the speed of the single phase digital meter the motor is to decreased in speed meaning the consumer load will be decreased as well.


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.

How do you reduce the speed of a 15 kW 3 phase motor without using variable speed control?

If the load is connected to the motor via belts, you can change the speed the load is turning by changing the pulley sizes. To get the load to slow down, increase the size of the pulley on the load; to get it to speed up, increase the size of the pulley on the motor. To reduce the speed of the motor itself, you'll have to alter the line frequency, which you can't do without a variable frequency drive attached to the motor.

Speed control of motor using SCR?

An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.


How do variable speed motors work?

A variable sped drive is sometimes also known as a variable frequency drive. These drives are used in electro-mechanical drive systems to control AC motor speed and torque.
