A drive system for a vehicle moving along a trackway, particularly a magnetic levitation train, includes a linear motor which has a stator extending along the trackway, and can be connected to a three-phase output voltage of an output transformer. An electrical power supply supplies a three-phase supply voltage which is converted into a three-phase alternating voltage of predeterminable frequency and amplitude by a converter unit. The alternating voltage being connected to the primary winding of an output transformer. To provide for more differentiated power adaptation it is proposed that the secondary winding of the common output transformer be provided with taps which, in transformer mode, can be connected and disconnected by a stepping switch for adjusting and correcting the desired output voltage.
