Pure-Python port of BOSL2's ``nema_steppers.scad``: models of NEMA-standard stepper motors and the masks that cut their mounting-hole pattern into a plate. :meth:`~bosl2.nema_steppers.NemaSteppers.nema_stepper_motor` builds a motor (body, plinth, shaft and blind screw holes) for a NEMA size; :meth:`~bosl2.nema_steppers.NemaSteppers.nema_mount_mask` is the bolt-pattern-plus-plinth cutout; :meth:`~bosl2.nema_steppers.NemaSteppers.nema_motor_info` returns the standard dimensions as a :class:`~bosl2.nema_steppers.NemaSpec`. .. autoclass:: bosl2.nema_steppers.NemaSpec :members: .. autoclass:: bosl2.nema_steppers.NemaSteppers :members: .. GENERATED-EXAMPLES (regenerate via scratchpad/gen_examples.py -- do not edit below) Examples -------- These mirror the examples in BOSL2's ``nema_steppers.scad``, rendered live through PythonSCAD. Examples that rely on BOSL2's attachment/anchor system, or on features not in this port, are omitted. .. rubric:: ``nema_stepper_motor`` NEMA 8: .. pythonscad-example:: NemaSteppers.nema_stepper_motor(size=8, height=24, shaft_len=15).show() NEMA 11: .. pythonscad-example:: NemaSteppers.nema_stepper_motor(size=11, height=24, shaft_len=20).show() NEMA 17: .. pythonscad-example:: NemaSteppers.nema_stepper_motor(size=17, height=40, shaft_len=30).show() NEMA 23: .. pythonscad-example:: NemaSteppers.nema_stepper_motor(size=23, height=50, shaft_len=40).show() .. rubric:: ``nema_mount_mask`` Bolt-pattern mask for a NEMA 14: .. pythonscad-example:: NemaSteppers.nema_mount_mask(size=14, depth=5, length=5).show() NEMA 17 with slotted holes: .. pythonscad-example:: NemaSteppers.nema_mount_mask(size=17, depth=5, length=5).show() NEMA 17 with round holes (length=0): .. pythonscad-example:: NemaSteppers.nema_mount_mask(size=17, depth=5, length=0).show()
