Problems solved by technology

On the other hand, as mentioned above, the magnetic modulation element is placed in the path of the magnetic flux going and returning between the armature and the field element, thereby causing the generation of eddy current
Such generation of eddy currents makes it difficult to support the magnetic modulation element by using metal members
[0032] Also, in the configuration disclosed in JP-B2-4505524, two inverters called PDUs (Power Drive Units) are required, so in the second case where the first rotary machine and the second rotary machine are arranged radially It is equally difficult to realize the two rotors described above in

Abstract

A magnetic modulation motor includes an armature, a magnetic induction rotor, and a magnet rotor. The armature is provided with a multi-phase winding with m pole pairs. The magnetic induction rotor includes k magnetic paths. In the magnet rotor, 2n permanent magnets forming a polarity region with n pole pairs are separately and annularly placed. The armature, the magnet rotor, and the magnetic induction rotor are arranged in the order from a radially outer side to a radially inner side. In the magnetic induction rotor, the magnetic path has two ends projecting toward a magnetic flux entry and exit located at an outer diameter face of the magnetic induction rotor, and forms a magnetic flux path between the magnetic flux entry and exit. The magnet rotor includes magnetic flux penetration region magnetically penetrated by magnetic flux between each circumferentially adjacent two permanent magnets.

Description

technical field [0001] The present invention relates to a magnetically modulated motor and electric transmission suitable for use in a powerplant for a hybrid vehicle driven by mechanical power from an internal combustion engine and electric power from a battery. Background technique [0002] As a related technology of a power transmission device for a hybrid vehicle, there is a common device that transmits power between an output shaft of an internal combustion engine and an input shaft of a gear through a motor and a CVT (Continuously Variable Transmission) Toggles between deceleration and back and forth motion. Recently, new techniques combining these functions have been proposed. [0003] For example, there is known a motor having a hybrid function that includes an armature corresponding to a stator, a magnet rotor fixed to a first rotation shaft, and a magnetic induction rotor fixed to a second rotation shaft. Based on the principle of magnetic modulation, the motor s...
