NEMA 17 Stepper: A Motor for 3D Printers

Stepper motors are brushless motors that use multi-toothed electromagnets to define the position. The electromagnets are fixed around a centralized gear. NEMA numbers define the standard dimensions of a faceplate for mounting a motor.  NEMA 17 stepper motors are stepper motors with a 43.2mm x 43.2mm (1.7 inch x 1.7 inch) faceplate. They are heavier and larger than a NEMA 14, but their size is what ensures more room for higher torque. NEMA 17 is the most common size for stepper motors used in 3D printers. They can be designed and manufactured to have different mechanical and electrical specifications to suit the 3D printer that you want to build.  Continue reading

Advantages and Applications of NEMA 34 Stepper Motor

The stepper motor (and power supply voltage) that you choose should depend on what you intend to do with it. Ideally, the stepper motor must provide sufficient power at the highest speed based exactly on what the application requires. Hence, you need to make sure that it does not exceed specific speed requirements. For instance, a maximum shaft power that you can sustain with a drive that functions at 80VDC and 7A is one third of a horsepower or at 250W. In this case, you need a triple or double stacked NEMA 34 motors.  Continue reading
