Embodiment Construction

[0022] A specific implementation of the dual mechanical port motor of the present invention is as follows: figure 1 As shown, this is a disc motor with axial flux, mainly composed of four components with a disc structure, which are the first stator 1, the first rotor 2, the second stator 23 and the second rotor in sequence 3. After assembly and molding, the two stators 1, 23 are located on the outer side, and the two rotors 2, 3 are located on the inner side of the two stators 1, 23, such as Figure 7 shown. Wherein, the second rotor 3 is connected with the output shaft 25 of the engine, and the first rotor 2 is connected with the drive shaft 26 of the vehicle. There is no mechanical connection between the two rotors 2 , 3 , and they are electromagnetically coupled entirely by the electromagnetic field in the second air gap 18 .

[0023] Assuming that the engine output speed is n1, the torque is T1, the output shaft speed is n2, and the torque is T2, the current frequency i...

Abstract

A brushless double-mechanical port electric machine comprises a first stator 1, a first rotor 2, a second stator 23 and a second rotor 3. The stators 1, 23 and the stator 2, 3 are all disk type structure. The two stators 1, 23 are positioned in outside of the two rotor 2, 3. The second rotor 3 is connected with an engine output shaft 25, the first rotor is connected with the vehical driving axle 26; the two rotors 2, 3 are coupled in electromagnetism depending on the electromagnetic field in the second air gap 18; armature windings are mounted on the two stators 1, 23, the power supply mode of the armature is random phase; a magnetic steel is adhered on the first rotor 2, the second rotor 3 is composed of a series of tooth structures; the second stator 23 and the second rotor 3 generate electromagnetic action to transfer the engine power to the first stator 2. The armature windings of the stator need not rotate avoiding the deficiency of power supply by the brush and the slip ring.

Description

technical field [0001] The invention relates to a motor, in particular to a motor with double mechanical ports. Background technique [0002] A dual mechanical port motor is an electric motor with two mechanical ports, the main field of application is hybrid vehicle drive. One of the mechanical ports is connected to the engine and the other mechanical port is connected to the vehicle drive shaft. Because the two mechanical ports of this motor are independent, the road load changes of a hybrid vehicle equipped with this motor are not directly transmitted to the engine. The engine can be controlled to always work in its high-efficiency zone, which effectively improves the efficiency of the entire power system and reduces emissions at the same time. It is of great significance in both energy saving and environmental protection. [0003] In invention patent CN1929243, CN1738163, CN1945939 and CN1694339 all relate to this motor. Although these motors have different specific i...
