Design and optimization of a low-cost direct-drive motor intendedfor low-duty CNC machines: Design and optimization of tubular linear motor

Nowadays, low-duty CNC machines use the conventional belt-driven system, which works well for relatively small machines. However this design brings several complications the engineer has to account for: creep; backlash; complex assembly and more importantly the limited stiffness of the belt. This limited stiffness results in belt stretch and...
