Problems solved by technology

Note that in the above description, when the rotary electric machine 10 is used as an electric motor in the range where the rotation speed is low, the motor torque decreases, however, when the rotary electric machine 10 is also used as a generator, for the same reason, in In the low rotation speed range, regenerative torque may be significantly reduced

Abstract

A stator has multi-phase stator coils that are wound around a stator core by concentrated winding. A rotor has rotor coils that are wound at multiple portions of a rotor core in the circumferential direction and diodes that serve as rectifier unit that is connected to the rotor coils and that varies the magnetic characteristics of the respective rotor coils alternately in the circumferential direction. A rotary electric machine driving system includes a decreasing / increasing pulse superimposing unit that superimposes decreasing pulse current for a pulse-shaped decrease on a q-axis current command for passing currents through the stator coils and that superimposes increasing pulse current for a pulse-shaped increase on a d-axis current command.

Description

technical field [0001] The present invention relates to a rotary electric machine drive system including a rotary electric machine having a stator and a rotor arranged to face each other, a drive unit that drives the rotary electric machine, and a control unit that controls the drive unit. Background technique [0002] As described in Japanese Patent Application Laid-Open No. 2009-112091 (JP-A-2009-112091), there is known a rotating electrical machine in which a rotor is provided with a rotor coil and an induced current is generated in the rotor coil by a rotating magnetic field , so that the rotor generates torque. The rotating magnetic field is generated by the stator and includes space harmonics. Furthermore, with this rotor motor, an induced current is efficiently generated in the rotor coil, so that it can obtain an effect of effectively increasing the torque acting on the rotor. Figure 23 to Figure 25 A schematic configuration of a rotating electrical machine describ...
