The radial pressure straight down born is relevant, and unrelated with the level of torque of mechanical rotary load load and power transmission shaft, once should
Pressure reduces even zero, will substantially reduce frictional resistance when bearing rotates, while can reduce vibrations and noise.
This plain bearing adds rotor and the frame mode of antigravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure
The gravity for bearing bearing radial direction reduces even to zero, and equivalent under weightlessness, acquisition is similar to magnetic suspension shaft
The effect held.Due to using motor and heat power machine and the direct cascaded structure of mechanical rotary load, now whole motor not only into
The power transmission shaft and flywheel of connection heat power machine and mechanical rotary load, coupling device is using when being rigidly connected, or when motor, heat
When engine and mechanical rotary load use same power transmission shaft, heat power machine and mechanical rotary load itself can be supported by also turning into
The antigravity bearing of power transmission shaft, thus the entirety of this generation antigravity effect is named as antigravity bearing.
Motor becomes bearing, and antigravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but in fact and need not be on motor body again
Extra increase part, bearing, rotor and stator are all that motor itself is existing, and simply by optimization stator winding, increase is drawn
Wire, produce unique antigravity Exciting Windings for Transverse Differential Protection structure, existing motor is turned into a huge antigravity bearing, and one more
High-quality zero-g inertial flywheel, and cost only has some thousandths of of magnetic suspension bearing, this is exactly the ingenious part of the present invention.When
Motor needs to make in electric motor mode or generator mode, by the switch unit in antigravity control module, to antigravity
The lead of Exciting Windings for Transverse Differential Protection switches over, and antigravity Exciting Windings for Transverse Differential Protection is returned to immediately in the stator winding of motor or generator.
Further, the present invention also has a variety of operating conditions, and therefore, flexibility is extremely strong.
In summary, serial power device of the invention and serial power apparatus control method are easy to implement, simple in construction.
Operation is flexible, and energy utilization rate is high, is adapted to popularization and application.
