We know that direction of a split phase motor can be reversed if the connection of one of the windings is reversed with respect to the other. In an automatic starter this can be achieved by using two contactors i.e., one for forward direction of rotation and the other for reverse direction of rotation. The connections for control circuit and the power circuit diagrams have been shown in Figure. The circuit does not need any further explanation as it is a simple forward reverse starter scheme.
