摘要： The present invention regards an rpm-multiplier or reducer device, and in particular an rpm multiplier or reducer for machines that work by removal of stock, such as machine-tools or the like, comprising a first electrical machine (4, 104), connected to a spindle of a machine-tool, and a second electrical machine (12, 112) to which a tool can be connected, said first and second electrical machines being connected electrically to one another so as to transmit the electric power generated by the first electrical machine (4, 104) to the second electrical machine (12, 112), which sets the tool in rotation, causing the rpm of the tool to vary with respect to that of the spindle of the machine-tool.
