Torque Slip Characteristics of Induction Motor
What are the factors that effect the torque slip characteristics of induction motor ?
The factors that effect the torque slip characteristics are rotor resistance, stator voltage , frequency and load conditions .
What is pull-out torque ?
It is the maximum torque that an induction motor can produce without losing synchronism.
What does the shape of torque slip curve indicates?
It shows a peak that indicates maximum torque the motor can produce at a specific slip.
Torque Slip Characteristics of Induction Motor
The torque slip characteristics of an induction motor is a plot that shows the relationship between the torque produced by the motor and the slip. Where slip is the difference between the speed of the rotating magnetic field produced by the stator and rotor speed. The torque slip characteristics are essential for optimizing the motor’s performance. The torque slip curve provides essential characteristics of the motor including its capabilities, efficiency and also operating range.
It is used to design and analyze motor systems for various applications. These are used in applications where high starting torque and high pull-up torque are required. It is used to predict motor behavioral characteristics under different load conditions and facilitates the design of control strategies to enhance performance.
Here in this article, we will discuss the definition of torque slip characteristics, torque slip characteristics in three-phase induction motors as well as single-phase induction motors, the effect of rotor resistance on torque-slip curve, advantages, disadvantages and applications of induction motors.
