The speed of a universal motor is usually reduced by using gearing.
Answer : The speed of a universal motor is generally reduced by using gear trains.
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 : The direction of rotation of universal motor can be reversed the by reversing the flow of current through either armature winding or field winding.
