ABSTRACT OF THE DISCLOSURE A feeding system for a linear motor transporta- tion system in which a number of discrete drive coil units or linear motor units are arranged along a track to generate a moving magnetic field for driving trains is disclosed. In the present feeding system, a number of feeding sections extend contiguously along the track and each of the feeding sections includes at least one power converter. Each feeding section is divided into at least two linear motor blocks each having feeder means. The linear motor units in each of the linear motor blocks are connected through associated ones of first switch means to the associated feeder means which is connected to the power converter of the associ- ated feeding section through associated ones of second switch means. Preferably, those adjacent two feeder means which belong to adjacent different feeding sections respectively are coupled together through third switch means. Preferably, the second switch means are corre- spondingly connected to the power converters through fourth switch means. Preferably, in each of the feeding sections, dynamic brake means is coupled to the junction of the second switch means and the feeder means or the junction of the second and fourth switch means through fifth switch means.
