STOPPING METHOD AND APPARATUS FOR MAGNETIC SUSPENSION CENTRIFUGAL MACHINE

摘要

The present application provides a method and a device for stopping a magnetic suspension centrifuge. The method comprises: a frequency-conversion cabinet connected with the magnetic suspension centrifuge judges a stopping state of the magnetic suspension centrifuge; if the stopping state is judged to satisfy a preset condition, the frequency-conversion cabinet switches a operating mode of a motor of the magnetic suspension centrifuge from an electrically-powered state mode to a power generation state mode, so as to convert the inertia mechanical energy of the motor when the motor stops into electric energy; and the frequency-conversion cabinet leads the electric energy into a power grid, so as to consume the electric energy. By means of the method and device for stopping the magnetic suspension centrifuge, the problem that the motor of the magnetic suspension centrifuge cannot be rapidly switched from an operating state to a stopping state when an exception occurs to a bearing or a bearing controller in the prior art can be solved.
