Embodiment 1

[0043] Such as Figure 7 Shown is the layout of the rotor damping winding 50 on the rotor iron core 60 of the turbogenerator of the present invention and the magnetic flux diagram of the magnetic field generated by it. In this embodiment, a 2-pole motor is taken as an example for illustration, and the stator has 24 slots. The first section 51 of the rotor damping winding is two coils A1 and A2, which are called group A coils, and the coils of group A are distributed in the circumferential direction. Here, the pitch of each coil is 1 / 3, spanning an electrical angle of 60 degrees, and can be set as required . The second segment 52 of the rotor damping winding is two coils B1 and B2, which are called group B coils. The coils of group B are distributed in the circumferential direction, and the span is the same as that of group A coils. The coils of group A and group B are arranged between the exciting windings 5, the coils of group A and group B with the same serial number are a...

Embodiment 2

[0053] Such as Figure 9 Shown is another form of the layout of the two-stage rotor vibration damping winding of the turbogenerator of the present invention and the magnetic field line diagram of the magnetic field generated by its electrification. Will Figure 7 The coils A1 and B1 are connected in reverse to form the coil A1, and the same axial magnetic field as the above-mentioned embodiment is generated after the current is passed through. At this time, the rotor core is still divided into two sections. The other coils are formed similarly and are arranged over the entire circumference of the motor.

[0054] In the above-mentioned embodiments, for the convenience of description and understanding, the stator core and the stator winding are not divided into sections, but they can also be divided into two sections in fact.

Description

technical field [0001] The invention relates to a motor, in particular to a steam turbine generator whose rotor arranges windings to weaken extreme frequency vibrations. Background technique [0002] Modern society cannot do without motors, and motors are used in transportation, industrial and agricultural production, information processing, and various fields of daily life. There are many types of motors with different structures, such as turbo generators, permanent magnet motors, electric excitation motors, etc. All kinds of motors will generate vibration and noise during the rotation process. Vibration noise is a kind of environmental pollution, which will have adverse effects on people's health and daily life; vibration and noise are more important in the military field. Therefore, it is of great significance to reduce the vibration and noise of the motor. [0003] The fundamental magnetic field and a series of harmonic magnetic fields exist in the air gap of the motor...
