In Marusaku's dual-hydrostatic hobbing machine, the hob spindle (B-axis) uses a 220 N·m direct-drive torque motor (1450 r/min rated, 5000 r/min max), and the workpiece table (C-axis) a 1200 N·m motor (45 r/min rated, 80 r/min max). The hob taper is Morse No.5.
Резание ведут два прямоприводных мотора по оси, без ремней и редукторов.

The machine's cutting motion is driven by two direct-drive torque motors, one per axis, eliminating belts and gearboxes that would add backlash and vibration.
The hob spindle is driven by a direct-drive torque motor rated at 220 N·m, with a rated speed of 1450 r/min and a maximum of 5000 r/min. The hob is held in a Morse No.5 taper.
The workpiece table uses a direct-drive torque motor rated at 1200 N·m, with a rated speed of 45 r/min and a maximum of 80 r/min. Together with the B-axis and an electronic gearbox, the 6-axis 4-linkage CNC keeps the hob and table precisely synchronized through the cut.
