- Characteristics of an induction motor include:
- Uses alternating current (AC) and operates based on electromagnetic induction1.
- Commonly used in industrial drives due to its cost-effectiveness, reliability, and high overloading capacity2.
- Efficiency can be optimized by adjusting rotor impedance: reducing impedance increases efficiency at high speeds, while increasing impedance provides more torque at low speeds3.

They are made up of a rotor, a stator and coils that convert electrical energy into mechanical energy using electromagnetic induction.www.dukeelectric.com/blog/all-about-induction-mot…It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable. It is also called asynchronous motor because it does not run at a synchronous speed. The induction motor requires very little maintenance and also it has high overloading capacity.circuitglobe.com/construction-of-induction-motor.htmlFig. 2.40 shows the characteristics of induction motors. When a motor is designed in such a way that impedance of the aluminum conductor of the rotor is reduced, its efficiency is increased in a high-speed range. And on the other hand, when designed to have a high impedance, the motor has an increased amount of torque in a low-speed range.www.nidec.com/en/technology/motor/basic/00027/ - See more
