Explanation

Universal motors are commonly used in household appliances. These motors can operate on either AC (alternating current) or DC (direct current) power, making them versatile for various applications. They are typically found in appliances such as vacuum cleaners, blenders, and power tools due to their high speed and lightweight design. While AC and DC motors are used in different applications, universal motors are particularly well-suited for the high-speed and variable load requirements of many household appliances. Stepper motors are more commonly used in precision control applications, such as printers and CNC machines.
