Which two types of motors are examples of electric motors?

Induction and synchronous motors are both examples of electric motors commonly utilized in various applications.

Induction motors operate on the principle of electromagnetic induction, where the rotor is induced to turn by the rotating magnetic field produced by the stator. These motors are widely used due to their simplicity, robustness, and efficiency, making them ideal for industrial and commercial settings.

Synchronous motors, on the other hand, maintain synchronization between the rotor speed and the frequency of the supply current. This characteristic allows for precise control over speed and is particularly advantageous in applications requiring constant speed under varying loads.

Both types leverage electrical energy to generate mechanical motion, highlighting their classification as electric motors. In contrast, the other options do not accurately categorize electric motors. AC and DC refer to the type of electrical current, while single phase and three phase describe the manner in which power is supplied. Thermal and mechanical motors pertain to different energy types or mechanisms and do not specifically refer to electric motor types.
