There is provided a technique for improving the efficiency of a generation system of a series hybrid electric vehicle The series hybrid electric vehicle is composed of: an engine; an n-phase generator driven by the engine; a rectifier generating a DC voltage from an n-phase AC voltage received from the n-phase generator; a battery charged with the DC voltage generated; a motor driving drive wheels; an inverter driving the motor on the DC voltage received from the rectifier and/or a DC voltage supplied from the battery; and a switch. The n-phase generator has n armature windings each having one end connected to a common neutral point. The rectifier has a negative terminal, a positive terminal on which a higher potential is generated than on the negative terminal, and n rectifying arms. Each of the n rectifying arms includes; a first diode connected between an intermediated node connected to the other end of the corresponding armature windings and the negative terminal; and a second diode connected between the intermediate node and the positive terminal. The switch is connected between the neutral point and the negative terminal.

The present invention provides a technique for enabling permanent magnets constituting the field magnet system of an IPM electric rotating machine to be embedded in a rotor core in a shallower depth. The IPM electric rotating machine is composed of a stator and a rotor. The rotor includes a rotor core and permanent magnets constituting the field magnet system. The rotor core has a side face opposed to the stator, and the permanent magnets are shallowly embedded so that the distance between the pole face thereof and the rotor side face is reduced. Furthermore, two adjacent permanent magnets are intensively spaced so that the following formula holds:0.3&#x3c;()/,where Lis the q-axis inductance of the rotor, and Lis the d-axis inductance thereof.

The stator () comprises a plurality of radially extending iron cores () and a plurality of windings () for generating a magnetic field in each iron core (). The rotor () comprises a plurality of permanent magnets () and a magnetic field line inducing body disposed between each permanent magnet () and the lateral surface.

Brushless motor

A battery operated, capacitor discharge type electronic, photoflash system having an electro-mechanical switching means for automatically disconnecting the battery to minimize unnecessary discharge of the battery. The system causes the battery to be disconnected at a predetermined time interval after a charge cycle has been started for a discharged main capacitor or after the main capacitor has been fully charged for a predetermined period of time.
