Problems solved by technology

[0006] However, in such a rotating electrical machine having an armature coil (motor pole coil), the output characteristics of torque and rotation speed are determined by the induced voltage corresponding to the number of turns of the armature coil, so it is possible to obtain a high-efficiency area in advance. However, in order to obtain driving force even in a region out of this region, it is necessary to intervene the transmission

Abstract

Provided is an electrical rotating machine of the double-rotor type adjustable to any desired output characteristic with a limited efficiency drop in energy transmission. The electrical rotating machine comprises a stator including armature coils (14) capable of generating magnetic flux when energized, an inner rotor driven to rotate when the magnetic flux passes therethough, and an outer rotor driven to rotate in a magnetic path of the magnetic flux that passes through the first rotor, the outer rotor having portions of different materials, in permeability, which are situated along the periphery of the outer rotor, the inner rotor having a plurality of rotor teeth situated along the periphery of the inner rotor and wound by winding coils (34) which generate induced current when linked by the magnetic flux generated by the armature coils, the stator including the armature coils therein, a plurality of winding coils (51, 52, 53) winding around each of poles to constitute the armature coil. And the number and circuit of the energized winding coils can be changeable.

Description

technical field [0001] The present invention relates to a rotating electric machine of the double rotor type. Background technique [0002] A rotating electrical machine is installed in various devices as a power source. For example, in the case of a vehicle, it is mounted alone to function as a power source for an electric vehicle, or is mounted together with an internal combustion engine to function as a power source for a hybrid vehicle. Especially in the case of a hybrid vehicle, high power transmission efficiency is required, and high torque is also required to ensure acceleration performance and step-crossing performance. [0003] Specifically, for example, as a power transmission path that connects an internal combustion engine, a rotating electric machine, and a driving wheel in series (series type), the following so-called range-extending method is sometimes used: the driving wheel is driven to rotate by the rotating electric machine, and the power of the internal c...
