The reason it is too vague is anything motor related requires load calculations and the power devices used must be chosen to accommodate the desired load. The mass and size of the load effects the torque and power requirements since the larger the load,
the greater the inertia and resulting start-up current. Please post a photo of a hand drawing taken with your cell phone or some other type of illustration with dimensions and mass specifications. In addition we would need to know more about the speed or
nature of the motion. For example, would you need to do micro-stepping ?
