Abstract: An electrically driven vehicle comprises a motor, a power storage device, a charging device configured to charge the power storage device by using electric power from an external AC power supply, and a control device configured to control the motor and the charging device. When execution of a drive-ready process is required during a charging termination process that is performed on termination of charging of the power storage device by the charging device, the control device interrupts the charging termination process, performs the drive-ready process and resumes the charging termination process after completion of the drive-ready process. This configuration enables the drive-ready process to be completed promptly even in the case of a start request during the charging termination process.

Said electric motor is constructed and arranged to provide at rest and at low rotational speeds a maximum torque higher than the resisting torque of the thermal engine at rest, and than about one third of the maximum torque of the thermal engine, in order to perform safely the starter function down to the lowest forecast temperature. Said electric motor is constructed and arranged to provide a maximum volumic torque of active parts of at least about 10 Nm/dm.sup.3. The controls associated with said electric motor are capable of providing the power corresponding to the maximum torque.

Abstract: In a starter having a planetary gear reduction mechanism and a shock absorbing device, a first friction plate of the shock absorbing device is engaged with an internal gear of the reduction mechanism to restrict the internal gear from rotating. A space is provided radially between the internal gear and a housing to allow rotation of the internal gear upon application of an impact shock. A cylindrical member which is harder than the housing is disposed between the space relatively movably against the housing and the internal gear so that the internal gear is restricted from directly contacting the housing.

Abstract: In a starter, a planetary gear reduction mechanism has pins supporting planetary gears and directly fitted into an outer member of a one-way clutch. The outer member rotates with the revolution of the planetary gear. An internal gear engaged with the planetary gears is connected with a rotary disk of a shock absorbing device disposed on the outer periphery of the one-way clutch through a connecting member and an elastic member. The connecting member has engaging projections engaged with the elastic member within the connecting recess of the internal gear. The engagement projections are housed within the connecting recess with some clearance provided in the radial direction. The internal gear is thus held radially movably with respect to the rotary disk via the connecting member.

Abstract: A particularly advantageous power converter, suitable for use in an engine powered generator system. A signal simulating a desired AC waveform is produced by a converter circuit at first and second converter output terminals. The converter circuit, responsive to respective switching signals applied thereto, selectively effects current paths between a juncture node and one of the first and second converter output terminals and between a common rail and the other of the first and second converter output terminals. A controller selectively generates control signals to the converter circuit and to a mechanism for varying the magnitude of the juncture node voltage, to create a predetermined waveform at the converter output terminals simulating the desired AC waveform. A number of alternative embodiments for producing a simulated sine wave are described, as well as accommodations for inductive loads, and mechanisms for minimizing power dissipation during the switching interval.

The limiting portion may be replaced by another limiting plate. Through holes for the through holes are formed at locations where the outer member is radially thick, e.g., between circumferentially adjacent two of the cam chambers.

Preferably, the tubular housing is an iron casting.

Abstract: Method and apparatus for accelerating a large inertia load from rest to a predetermined speed of rotation by means of a synchronous dynamoelectric machine. A synchronous dynamoelectric machine, such as a turbine generator, which is mechanically coupled to a gas turbine prime mover, is started synchronously to bring the gas turbine up to a speed which exceeds its stall speed under load. The rotor field winding of the synchronous dynamoelectric machine is connected to receive direct current excitation from a rotatable rectifier assembly of a brushless exciter. During starting, a quadrature axis winding disposed around the stator of the brushless exciter is energized by single phase alternating current. Alternating current excitation is induced by transformer action within the rotor armature winding of the exciter and is applied to the rotor field winding after being rectified by the rotatable rectifier assembly.
