Abstract
A method and a device for stopping a magnetic suspension centrifuge includes: 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. Accordingly, 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.
