To provide a perfectly pollution-free engine through a motor of the generator having the semiconductor with an armature of continuously generating an eddy-current, without running short by a support of the semiconductor (thyristor).

The armature (1) and a brush (3) are provided in a circular field (6), a magnetic field is always continuously generated by the semiconductor (4), the eddy current is generated, the generator with the semiconductor (5) generates electricity by rotating the armature. For stopping this operation, a gate turn-off thyrister (7) which can cutoff main current by a gate is installed in the generator having semiconductor.
