The speed of a universal motor is generally reduced by using gear trains.
Answer : The speed of a universal motor is usually reduced by using gearing.
Answer : Speed control of a universal motor is achieved by varying field flux with tapped field windings, connecting rheostat in series, applying variable voltage by means of silicon controlled rectifier, applying variable voltage by means of variable auto-transformer.
Answer : The speed control of universal motor used for sewing machines is by varying the resistance.
Answer : The speed/load characteristics of a universal motor is same as that of D.C. series motor.
Answer : A universal motor can run on either A.C. or D.C.
