A Universal Motor is a type of electric motor that can operate on both alternating current (AC) and direct current (DC). It is commonly used in household appliances like vacuum cleaners and power tools due to its high speed and efficiency. The design typically includes a series-wound configuration, allowing it to produce a high starting torque. These motors are compact and lightweight, making them ideal for portable devices. However, they can be noisy and may require maintenance over time. The versatility of a universal motor makes it a popular choice in various applications, from small gadgets to larger machinery.
