The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the… ...

Stepper motors are great for projects that require accurate control of motion. 3D printers, CNC machines and plotters are often built using these useful devices. [InventorArtist] built a stepper-ba… ...

For example, a motor with a torque of 2.3 N m at 500 rpm when used with a 3:1 gearbox will have a 6.9 N m output, but the motor’s rpm will climb to 1,500 rpm to drive the gearbox.

Stepper motors have simple designs and controls, and don’t require tuning or adjustment. They provide excellent torque at speeds under 1,000 rpm and are one-half to one-third the cost of ...
