Nema17 Linear Stepper Motor with lead screw 4.0kg.Cm 42HS40-1004YAL 295mm length for 3D printer
a linear stepper motor is essentially a variation of the rotary design, cut radially and laid out flat. Similar to their rotary counterparts in operation and performance, a linear stepper motor is typically run as open-loop systems and are capable of providing high resolution at high speeds and accelerations.
