variator gearbox

A lot more than 50% of the compression and pumping systems above 3 MW need a variable-speed drive. Often medium-voltage motors fed by frequency converters and parallel shaft gears are selected. Others are employing epicyclic gears with a hydrodynamic superimposition drive.

Taking benefit of the condition of the art in electric powered motors and frequency converters, the driving program for the superimposition of the earth carrier is founded on a Permanent Magnet Synchronous Superimposition (SI) motor and a dynamic Front-End Cycle Converter. So – E stands for Electric.
That is a high-speed gear drive system incorporating components that allow the use of a low-cost constant-speed (electric) Variator Gearbox driver for a variable-speed application.

It started with hydraulic liquid couplings generating slippage with results very little much better than the throttle.
The design of hydraulic clutches then improved and included a torque converter and a superimposed epicyclic drive.
Adjustable Frequency Drives (VFD) were developed and, simultaneously, the price of the shaft trains improved, and so did efficiency. The problem of THD (Total Harmonic grid Distortion) rose and kept VFD out of many applications.

Taking advantage of the state of the artwork in electric motors and frequency converters, the driving system for the superimposition of the earth carrier is founded on a Permanent Magnet Synchronous Superimposition (SI) engine and an Active Front-End Cycle Converter. So – E means Electric.
That is a high-speed gear drive system incorporating elements that allow the use of a low-cost constant-speed (electric) driver for a variable-speed application.

All of the over plots were taken by analyzing the current to the engine. In a normal circumstance, the vibration will become monitored and kept on a periodic basis. If the 360 Hz signal is present in the vibration spectrum, it isn’t normally of any concern. If, however, various other unexplained frequencies appear in the vibration spectra, after that it would be advisable to take a look at both the current waveform and the current spectrum. In the webpages that follow, a few examples of problems discovered in DC drives and motors are presented.”
