Problems solved by technology

[0005] In addition, in the electric motor in an example of the above-mentioned prior art, for example, in the case of controlling the phase difference between the first and second rotors according to the rotational speed of the motor, only in the operating state of the motor, that is, the state in which the centrifugal force acts according to the rotational speed The phase difference between the first and second rotors can be controlled, but there is a problem that the phase difference cannot be controlled at an appropriate moment including the stop state of the motor
In addition, as in the case where the electric motor is used as a drive source and mounted on a vehicle, in a state where external vibrations tend to act on the electric motor, it may be difficult to properly control the first and second rotors only by the action of centrifugal force. Phase difference problem
Also, in this case, since the phase difference is not limited to the control of the power supply voltage fluctuation in the power supply of the motor, for example, there may be a problem that the magnitude relationship between the power supply voltage and the reverse voltage of the motor is reversed.
[0006] In addition, for example, in the case of controlling the phase difference between the first and second rotors based on the speed of the rotating magnetic field generated in the stator, the speed of the rotating magnetic field is changed, so the problem of complicated control processing of the motor occurs.

Abstract

A motor includes rotation means having a first member arranged as a rotatable unitary block with an outer circumference side rotor and a second member arranged as a rotatable unitary block with an inner circumference side rotor. The first member and the second member forms a pressure chamber inside the inner circumference side rotor. By supplying a work fluid into the pressure chamber, it is possible to change the relative phase between the inner circumference side rotor and the outer circumference side rotor.

Description

technical field [0001] The present invention relates to electric motors. [0002] This application takes Japanese Patent Application Nos. 2006-060064, 2006-060065, 2006-060066, and 2006-060067 as basic applications, and incorporates the contents thereof. Background technique [0003] Conventionally, a motor is known that includes, for example, first and second rotors arranged concentrically around a rotation axis of the motor, and controls the first and second rotors according to the rotational speed of the motor or the speed of the rotating magnetic field generated by the stator. The relative position in the circumferential direction of the second rotor is a phase difference (for example, refer to Patent Document 1). [0004] In this motor, for example, when the phase difference between the first and second rotors is controlled according to the rotational speed of the motor, the circumferential directions of the first and second rotors are changed through a member that is ...
