Pancake Stepper Motor
Pancake motors are generally used for lightweight applications, such as direct drive extruders, or in places where a larger motor won’t fit, for instance in a small, portable 3D printer. The advantages of such motors are generally attributed to their small sizes. This allows them to be put places where a larger motor would get in the way or cause too many inertial problems. One of popular uses of this size motor is for direct drive extruders on high-speed printers. Additionally, for smaller printers, this variety of motor are favored over their beefier counterparts. This is because they cost less, but still have a suitable amount of torque for moving small gantries.
