Problems solved by technology

[0008] According to the above-mentioned conventional power plant, two soft magnetic body arrays are indispensable in the first rotary machine. Therefore, the size of the first rotary machine increases and the manufacturing cost increases. As a result, the power plant itself increases in size and increase in manufacturing costs
Furthermore, due to the structural characteristics of the first rotating machine, only the rotational difference between the first rotor and the second rotor and the speed relationship in which the rotating magnetic field is equal to the rotational difference between the second rotor are established, so there is a degree of freedom in design low problem

Abstract

The present invention provides a power device which is reduced in size, is produced at reduced cost, and has increased degree of design freedom. The power device (1) is provided with an engine (3) and first and second rotating machines (10, 20) and drives front wheels (4) by power of the first and second rotating machines. The first rotating machine (10) is provided with first and second rotors (14, 15) and a stator (16). The ratio between the number of armature magnetic poles occurring in the stator (16), the number of magnetic poles of the first rotor (14), and the number of soft magnetic body cores (15a) of the second rotor (15) is set to satisfy the relationship of 1 : m : (1 + m) / 2 (where m <> 1).

Description

technical field [0001] The present invention relates to a power plant that drives a driven part with power, and particularly relates to a power plant that includes a heat engine and a rotating machine as a power source. Background technique [0002] The present applicant has already proposed a power plant described in Patent Document 1 as a conventional power plant. This power unit is a device that drives the drive wheels of a hybrid vehicle, and is described in Patent Document 1 figure 2 , 3 In the illustrated example, an engine, a first rotating machine, and a second rotating machine are provided as power sources. [0003] The first rotating machine includes a cylindrical case, an input shaft and an output shaft rotatably supported by the case; a stator provided on the inner wall of the case along the circumferential direction; a first rotor accommodated in the case; The second rotor and the like between the rotor and the stator, the stator, the first rotor, and the sec...
