What are the advantages and disadvantages of squirrel cage motor?
What are the advantages and disadvantages of squirrel cage motor?
Squirrel Cage Induction Motors requires less conductor material than slip ring motor, hence copper losses in squirrel cage motors are less results in higher efficiency compared to slip ring induction motor.
What are the advantages and disadvantages of wound rotor over squirrel cage rotor in case of induction motor?
As a result the inrush current is reduced. Another important advantage over squirrel-cage motors is higher starting torque. The speed and torque characteristics of a wound-rotor motor can be adjusted by changing the external resistance, unlike a squirrel cage motor which has a fixed characteristic.
What is advantage and disadvantage of induction motor?
Induction motors always operate under lagging power factor and during light load conditions they operate at very worst power factor (0.2 to 0.4 lagging). Some of the disadvantages of poor power are increase in I2R losses in the system, reduction in the efficiency of the system.
What are the advantages and disadvantages of slip ring induction motor over squirrel cage induction motor?
Initial and maintenance cost is more compared to squirrel cage motor because presence of slip rings, brushes, short circuiting devices etc. Speed regulation is poor when operated with external resistances in rotor circuit. Efficiency and power factor of slip ring motor is lower compared to squirrel cage induction motor.
Which of the following is disadvantages of squirrel cage induction motor?
Some disadvantages of squirrel cage induction motors are: Very poor speed control. Although they are energy efficient while running at full load current, they consume a lot of energy on startup. They are more sensitive to fluctuations in the supply voltage.
What are the advantages of squirrel cage motor?
Some advantages of squirrel cage induction motors are:
- Simple and rugged construction.
- The low initial as well as the maintenance cost.
- Maintains constant speed.
- The overload capacity is high.
- Simple starting arrangement.
- High power factor.
- Low rotor copper loss.
What are the advantages of squirrel cage induction motor?
What are the disadvantages of squirrel cage induction?
Some of disadvantages or demerits of squirrel cage induction motors are listed below: Main disadvantage of squirrel cage induction motor is that they have poor starting torque and high starting currents.
What are the advantages of a squirrel cage motor?
Advantages of Squirrel Cage Induction Motor: Squirrel Cage Induction motors are cheaper in cost compared to Slip Ring Induction motors. Requires less maintenance and rugged construction. Squirrel cage motors are explosion proof due to the absence of brushes slip rings and brushes which eliminates the risks of sparking.
What kind of motor looks like a cage?
These motors are a type of induction motors, which harness electromagnetism to generate motion. They are so-called squirrel cage motors because the shape of their rotor looks like a cage.
