An in-wheel motor system can drive an in-wheel motor stably, and also allows power feeding from the road surface, even when transmission and reception coils are misaligned. An in-wheel motor system (1) includes a power transmitter (100) that utilizes a resonance phenomenon using a magnetic field. The power transmitter (100) transmits power (P) wirelessly from the vehicle body to an in-wheel motor (10) mounted in a wheel. The in-wheel motor system (1) may also include a communication interface (110) that communicates between the vehicle body and the wheel, and the communication interface (110) may transmit a control signal (CTL) for driving the in-wheel motor.

A slider is slightly moved in a direction in which both side surfaces of the slider come in contact with inclined surfaces of impact mitigating parts of neighboring contact strip pieces. For this reason, the inclined surface of the impact mitigating part of the contact strip piece which the slider approaches is relatively downwardly slid with respect to one side surface of the slider. In addition, the inclined surface of the impact mitigating part of the contact strip piece from which the slider moves away is relatively upwardly slid with respect to the other side surface of the slider. As a result, since an impact generated between the contact strip piece and the slider is mitigated by the impact mitigating part without fitting the slider into a stepped section between the neighboring contact strip pieces, the slider is smoothly transferred from the one contact strip piece of the neighboring contact strip pieces to the other contact strip piece.

Main circuit of an electric power generating apparatus for dispersed power supply, having a permanent magnet type electric power generator driven by windmill or waterwheel and having three windings, each inducing a different value of induced voltage, AC outputs of the generator rectified by rectifiers, and DC outputs of the rectifiers summed in parallel for output. First and second reactors are respectively connected in series between first and second rectifiers and output terminals of first and second windings, the first winding inducing the lowest induced voltage among the three windings, the second winding inducing the second lowest. A capacitor is connected between a third rectifier and an output terminal of a third winding inducing the highest induced voltage. The sum of inductive impedance by internal inductance of the third winding and capacitive impedance by the capacitor is capacitive impedance within a range of rotational speed of the generator.
