If going for the smaller NEMA 14 motors, aim for the high torque option. You need approximately 1400 g.cm of holding torque or more to be safe. NEMA 14s are neater, lighter and smaller, but can be hard to get hold of. NEMA 17s are quite easy to get in the specification that Mendel needs, but are bulkier and less neat. NEMA 14s are running near the edge of their envelope: they will get warm. NEMA 17s are well inside what they can do, and will run cool.
Below is a list of possible suppliers and motors. Please add to it. If you have built a Mendel successfully with a given motor, remember to put Yes in the tested field.
