Problems solved by technology

However, due to the low insulation level of non-stacked DC motors, it is difficult to withstand the rapid changes in the current and voltage of the digital electric transmission device. Therefore, effective suppression measures must be taken to not only suppress the rapid changes, but also ensure the dynamics required by the machine. response

Description

technical field [0001] The invention relates to the technology of numerical control machine tools, in particular to a technology for controlling a non-laminated direct-current motor with a digital direct-current speed regulating device. Background technique [0002] The traditional non-laminated DC motor is powered by a generator set, which has high energy consumption, high noise, and simple electrical functions, which cannot meet the requirements of modern numerical control control. The new digital DC speed regulating device is controlled by computer technology, with fast response speed, energy saving and various control functions. However, due to the low insulation level of non-stacked DC motors, it is difficult to withstand the rapid changes in the current and voltage of the digital electric transmission device. Therefore, effective suppression measures must be taken to not only suppress the rapid changes, but also ensure the dynamics required by the machine. response. ...
