摘要： In a motor having a pawl-shaped magnetic pole, if a coil is wound like a ring shape so as to be formed, one leader line can be generally drawn out to an external portion from a position close to an outer periphery of a stator, however, the other leader line is drawn out to the external portion from an inner periphery of the stator. Accordingly, the leader line occupies a part of the inner space formed by the stator core, so that there is generated a problem that a space factor of the coil is reduced. Accordingly, an object of the present invention is to improve the space factor of the coil. In order to achieve the object mentioned above, a space passing wirings of a plurality of coils therethrough is provided in a part of the pawl-shaped magnetic pole of the stator core of the stator having the pawl-shaped magnetic pole. Accordingly, one of leader lines of the coil is drawn out from an outer peripheral portion (or an opposite side to a side facing to the rotor) of the stator, and the other is drawn out in an axial direction from the space of the claw-shaped magnetic pole of the stator. Therefore, it is possible to do away with an influence by the leader line, it is possible to increase a winding number of the coil even in the same space, and it is possible to improve a downsizing of the motor.

摘要： A composite power transmission mechanism 10, comprising the combination of a planetary gear unit 15 and a differential planetary gear mechanism 16, wherein a planetary gear is connected with a drive shaft of a vehicle, while other three gears let the shafts of the motor 12, a motor 13 and an engine 11 rotate respectively. The drive shaft of the vehicle is made to rotate by means of the planetary gear of the composite power transmission mechanism; since the rotation of different sources of a driving force, i.e., those of the motor 12, the motor 13 and the engine 11, can be transmitted to one another by only one meshing of the gears, the mechanical loss that is dependent on the number of times of the meshing of the gears can be reduced to a minimum.

摘要： A synchronous motor control system includes a synchronous motor 1, an inverter 3 and a controller 4 wherein a current differential detecting unit 13 detects a variation of a motor current when the three phases of the motor 1 is short circuited by the inverter 3, namely at the moment when a carrier wave in a PWM signal generator 9 assumes maximum or minimum value, in a calculating unit 14 a phase &ggr; from &agr; axis of a stationary coordinate system to a three phase short circuited current differential vector is calculated, a phase &dgr; is estimated from d axis to the three phase short circuited current differential vector by making use of d axis current id and q axis current iq on d-q axes coordinate system in the controller 4, thereafter the magnetic pole position &thgr; with respect to &agr; axis is calculated from the phases &ggr; and &dgr;, based on thus calculated magnetic pole position &thgr;, d-q axes control units 11, 7 and 8 are constituted to control the synchronous motor, thereby a highly reliable control system for the motor which permits a detection of the magnetic pole position without affecting a state of applied voltage thereto while performing a usual PWM control with a low cost controller.

摘要： An inverter system providing both an improvement in the voltage utilization factor and a reduction in the switching loss uses a two-phase switching method. In the inverter system, an .alpha.-axis voltage command value; v.sub..alpha.r and a .beta.-axis voltage command value v.sub..beta.r are input to a stop phase selection means. Six sections are judged based on the values v.sub..alpha.r and v.sub..beta.r to select phases for which it is allowable to stop pulse width modulation control in a two-phase switching method. Then, a phase having the largest absolute value of current is selected among the phases for which it is allowable to stop pulse width modulation control using a U-phase current i.sub.u and a V-phase current i.sub.v. This information is a control mode S. Based on these, two-phase switching calculations are performed by a dead-time compensation calculation means and a pulse width modulation generating means. By doing so, the switching loss can be reduced.

摘要： In a controller for an electric vehicle, a voltage current phase difference calculating circuit calculates a vector phase .theta..sub.c from a voltage command value and the primary current of an alternating current motor. The vector phase .theta..sub.c is input to a second voltage command circuit which calculates a second d-axis voltage command value and a second q-axis voltage command value using the vector phase .theta..sub.c and d-axis and q-axis current differences. By correcting the voltage command value using the second d-axis and second q-axis voltage command values, the stability of the current control system is improved. By controlling the electric vehicle using such a system, a stable current control can be attained even when the electric vehicle is driven under a regenerative running state or a weak magnetic field control state.
