Which type of motor is commonly used in household applications?

The selection of an AC Induction Motor as the correct answer is based on its prevalent use in household applications. These motors are favored due to their robustness, reliability, and efficiency in converting electrical energy into mechanical energy. They operate on the principle of electromagnetic induction, which allows them to have a simple construction and minimal maintenance needs.

In household settings, you will frequently find AC Induction Motors powering essential appliances such as refrigerators, washing machines, and fans. Their design is well-suited for these applications, as they can easily handle varying loads and operate continuously over extended periods without significant wear.

While DC Motors, Stepper Motors, and Synchronous Motors do have their applications, they are less commonly used in general household environments. DC Motors are often found in smaller devices or toys due to their simplicity and ability to control speed and direction. Stepper Motors are more specialized and typically used in applications that require precise control, such as printers and CNC machines. Synchronous Motors, while efficient, are often used in industrial settings and less frequently found in common household appliances. Thus, AC Induction Motors remain the go-to choice for everyday use in homes.
