Optimising Start-Up of a Crankshaft Press Drive

OPTIMISING THE START-UP OF A 10Hz BOOSTER POWER SUPPLY

The Synchrotron Radiation Source (SRS) at Daresbury Laboratory has a 600MeV Booster, fed by an energy storage power supply configuration (White Circuit). The design consists of two power supplies : an AC source to supply the losses to the parallel resonant circuits and a DC supply to fully bias the AC sinewave. In a recent modernisation of the control electronics, different methods of achieving...

A start-up method for a speed sensorless stator-flux-oriented vector-controlled induction motor drive

This letter describes a zero-speed start-up method of a speed sensorless stator-flux-oriented direct vector-controlled induction motor drive with the help of a machine current model that does not use any speed signal. The machine starts smoothly with vector control at finite developed torque and then transitions to the standard direct vector-control mode with the voltage model signals as the sp...

Studying the process of transformation of the start-up to the academic spin off

At todaychr('39')s universities, we are witnessing the emergence of startup companies by the startup teams by student and academic teams; unfortunately, most startups face barriers to success. On the one hand, one of the new topics entering the fourth-generation universities and can be a good target for the future of the startups; the existence of academic spin-offs, centered around scholars...

Calculation of Optimal Value of Taper for the Drive Pin of the Scroll Compressor Crankshaft

A New Start-up Demonstration Test

In this paper, we introduce and study a new acceptance / rejection rule suitable for use in start up demonstration tests. According to this rule, the equipment is accepted if k consecutive successes occur, while the equipment is rejected if two failures separated by at most 2 − r successes are observed. General formulae and analytic expressions are given for the probability mass function, the m...
