Method of manufacturing a molding with a core

The present invention provides a method for manufacturing a molding with a core by using compression molding means having upper and lower double-structured punches; the method comprising the steps of supplying molding material for the core and molding material for the outer layer respectively, the step of compression-molding the molding material for the core and / or the molding material for the outer layer, and the step of compression-molding the whole molding with a core, wherein: the step of supplying the molding material for the outer layer posterior to the step of supplying the molding material for the core is performed until a tip of the lower center punch finally takes a position protruding from a tip of the lower outer punch; and the step of compression-molding the whole molding with a core is performed with the tips of the lower center punch and the lower outer punch aligned with each other. This method can be expected to bring about the effect of enhancing the strength of a portion of outer layer forming the sidewall of the molding and / or the effect of allowing the molding material for the outer layer supplied after the step of supplying the molding material for the core to be led to under the temporary molding of the core thereby making it possible to manufacture a molding with a core through the molding material supply step performed twice.

Torque and power fluctuation suppression method of variable frequency transformer

The invention relates to a torque and power fluctuation suppression method of a variable-frequency transformer. The method comprises the steps of S1, collecting related signals; S2, processing the related signals to obtain a stator side power grid positive sequence voltage direct current component, a stator voltage direct current component and a current direct current component; S3, processing according to a preset voltage control equation to obtain direct-current components of all voltage reference values of a series three-phase converter; S4, carrying out coordinate transformation processingto obtain voltage reference values of the series three-phase converter, and adding the voltage reference values of the series three-phase converter to obtainthe voltage reference value of the seriesthree-phase converter in a two-phase static coordinate system; and S5, carrying out space vector modulation on the voltage reference value of the series three-phase converter to obtain a control signal of a switch of the series three-phase converter, and inputting the control signal into a controller to realize suppression of a torque and a power fluctuation of the variablefrequency transformer. In the invention, the variable frequency transformer has a capability of operating under bilateral imbalance and a harmonic power grid voltage.
