A universal motor is one of the single-phase motors that can be operated on either direct current or single-phase alternating current at approximately the same speed. This motor is most popular in the fractional-horsepower size and is used in appliances such as vacuum cleaners, food mixers, drills, sewing machines, and power handsaws.
