Embodiment Construction

[0013] specific implementation plan

[0014] The three-phase motor system and structural details of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] As shown in Figure 1, two single-motor rotors (B) are fixed in series on the rotor shaft (A), and two single-motor stators (C) are concentrically fixed in series in the motor housing (D).

[0016] In Figure 2, the circuit connection method of the two stator windings is: U of the first stator (1) winding 2 terminal and the second stator (2) winding V 1 End connection; V of the first stator (1) winding 2 End second stator (2) winding W 1 end connection; W of the first stator (1) winding 2 terminal and the second stator (2) winding U 1 end connection.

[0017] W of the a, b, c three-phase windings of the second stator (2) 2 , V 2 , U 2 connected side by side.

Abstract

The invention relates to a proposal for combining two three-phase motors by electricity, but both the mechanical structure and the electric apparatus structure have not achieved the optimal level; thereby two simplex three-phase motors which have same control power in a same point through mechanical joint, the improvement of the electric construction and electric series combination is capable of forming a new integrative motor, and the volume is reduced, and the function is more reliable, and the two simplex three-phase motors are capable of being connected in series and combined to be an integrative motor, and running simultaneity.

Description

technical field [0001] The invention relates to an electric machine, especially a three-phase motor. Background technique [0002] There has been a scheme of combining two three-phase motors through electrical connection, as described in "A Combination and Manufacturing Method of Energy-Saving Motors" (CN200410017157.1). This scheme has a certain power-saving effect, but the mechanical structure and the electrical structure have not yet reached the optimum level, so there is still room for improvement. Contents of the invention [0003] In order to solve the problem that the combined structure level of two three-phase motors with the same power controlled at the same point is not high, the present invention provides a three-phase motor, which can solve the problem of two motors with the same power controlled at the same point The problem of low level of combined structure of three-phase motors. [0004] The technical scheme that the present invention solves the problem t...
