The SCR controls to impose different break-over voltage onto the stator to control
the size of rotation speed, and when the rotation speed increases up to a null
value (600rpm, the complete machine), switch off the high-speed tap via K1 to
reach 1400rpm, the maximum rotation machine of complete machine; adjust the
rotation direction of rotator via K2 and K3 so as to make the complete machine to
revolve clockwise and anti-clockwise.
