Abstract
PURPOSE:To prevent overcurrent, by reducing output voltage from an inverter based on an output from a detector for detecting missing of a reaction plate. CONSTITUTION:When an electrical vehicle 11 is driven forward and a missing portion detector 15 arrives at point (a) where a reaction plate 14 is missed, a missing portion detection signal is fed to a subtracter 7 so as to subtract an inverter voltage command. Subsequently, the electrical vehicle 11 is driven further and the primary coil 13 in a front linear motor passes through the reaction plate 14 missing portion (a) followed by passage of the primary coil 13 in a rear linear motor. Since exciting voltage is reduced previously. exciting current for single motor does not increase significantly at the reaction plate 14 missing point (a).
