    摘要: An inverter circuit for a brushless motor utilizes an IPM integrated circuit module. The module includes insulated gate bipolar transistors and has outputs for providing driving signals to the brushless motor based on control signals received at inputs from a microcontroller. A sensing circuit measures the current at the lines from the outputs of the IPM integrated circuit module to the motor. A feedback circuit processes the current measurements and provides signals corresponding to the measured current to the microcontroller.

    摘要: A computer-implemented method of design of ruled surfaces may comprise the step of accessing data defining guiding curves P(u) and Q(v) and a cost function ƒ(t,w). Given P(u) and Q(v), the unknown coupling is a parameterized curve s(t(s),w(s)). The method further comprises defining an objective function of the type J=J(ƒ,t,w), involving both ƒ(t,w) and coordinates t, w of the coupling curve. Then, optimizing the objective function J makes it possible to obtain the target coupling curve. Finally, a ruled surface S(s,λ)=λQ(w(s))+(1−λ)P(t(s))is provided, according to the guiding curves P(t(s)) and Q(w(s)), composed with the coordinates t,w of the coupling curve previously obtained. In addition, the objective function is further constrained at the optimization step such that arguments t,w of the cost function ƒ(t,w) are regulated by a regulation function μ.
