Stepper motors for robotics
Stepper motors are a class of widely used engines in many applications such as 3D printers or robotics. They convert an electrical pulse in a defined angular movement called steps. Their advantage is that they have a potentially high torque and are quite accurate.
There are 5 products.
The NEMA 17 unipolar/bipolar stepper motor (200 steps/rev) proposed here by Pololu has a holding torque of 3.2 kg.cm and can be controlled in two different modes by compatible stepper motor drivers.
This Pololu hybrid bipolar stepper motor is ideal for all projects requiring precise motor position control.
This high-torque hybrid stepper motor can operate in bipolar or unipolar mode depending on the motor controller used.
The Sanyo Pancake Stepper Motor is an ultra-flat (pancake-shaped) stepper motor distributed by Pololu.
