The speed-torque characteristic of a three-phase induction motor is typically represented by a graph that shows the relationship between the motor's speed and torque. The graph typically consists of two curves: the torque-speed curve and the breakdown torque curve.
The torque-speed curve shows the relationship between the motor's torque output and its speed. At low speeds, the motor is able to produce a high amount of torque, which decreases as the speed of the motor increases. This curve typically follows a linear relationship until it reaches the motor's rated speed, at which point the torque output decreases rapidly.
The breakdown torque curve represents the maximum amount of torque that the motor can produce without stalling. This curve typically shows a peak value at a certain speed, known as the breakdown torque speed. Beyond this speed, the motor is unable to produce any additional torque and will stall if the load increases.
Overall, the speed-torque characteristic of a three-phase induction motor shows that the motor is able to produce a high amount of torque at low speeds, but this torque decreases as the speed of the motor increases. Additionally, there is a maximum torque limit that the motor can produce before stalling.

The speed-torque characteristic of a three-phase induction motor is a graph that shows the relationship between the speed of the motor and the torque that it produces. The graph is typically divided into four regions:
- Starting region: In this region, the motor is at rest and the torque is maximum.
- Accelerating region: In this region, the motor is accelerating and the torque is decreasing.
- Running region: In this region, the motor is running at a constant speed and the torque is constant.
- Braking region: In this region, the motor is decelerating and the torque is negative.
The speed-torque characteristic of a three-phase induction motor is important because it can be used to determine the performance of the motor under different operating conditions. For example, if the load on the motor is increased, the motor will slow down and the torque will increase. This information can be used to select the correct motor for a particular application.
The speed-torque characteristic of a three-phase induction motor can be affected by several factors, including:
- The number of poles: The number of poles in the motor affects the speed of the motor. A motor with more poles will run at a slower speed.
- The voltage applied to the motor: The voltage applied to the motor affects the torque of the motor. A motor with a higher voltage will produce more torque.
- The load on the motor: The load on the motor affects the speed and torque of the motor. A motor with a heavier load will run at a slower speed and produce more torque.
By understanding the speed-torque characteristic of a three-phase induction motor, you can select the correct motor for your application and ensure that it will perform as expected.
