The present invention provides a drive control system, which uses diver in an information controller to control part of the linear induction motor to disconnect from the main circuit and the residual energizing linear induction motor to burden the thrust/ brake force required for constituting whole body, when the thrust/ brake force required for constituting whole body is low. Accordingly the invention resolves the reduced power efficiency problem under lower thrust/ brake force required for constituting whole body when an information controller controlled by a drive for constituting whole body is applied to a linear induction motor electric car.
