It is small, at 1.6 inches (40 mm) square, and provides up to 2 amps drive current for one axis and up to 1 amp for the second, with an optional second stepper or bi-directional dc driver daughtercard ...

He’s also done a nice job packaging the Arduino, stepper motor driver boards, and the discrete components all onto a single custom surface mount PCB. Wire straightener and feeder ...

Some might complain that the 3+Pi doesn’t allow for easily swapping out the stepper drivers if you manage to cook one like on the Arduino CNC shield, but realistically you could say the same ...

The αSTEP AZ Series stepper motor driver offers superior high speed open loop performance with closed loop control. It incorporates a battery-free, absolute mechanical encoder for absolute-type ...

The AMIS-30522 is a microstepping stepper-motor driver for bipolar-stepper motors. The IC can be interfaced via I/O pins and the SPI bus to an external microcontroller or a DSP.

Then select a stepper with at least twice as much torque as required at the target operating speed, and use a motor rated at about ¼ supply voltage. Next, look at the driver current required to ...

Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable ‘Click’ boards. Called Power Step 2 Click, the board “is based on the powerSTEP01, a 1/128 microstepping ...

Multifunction printers, for example, often use a three-phase BLDC-motor driver or a stepper-motor driver (either one channel or two channel) for the paper mover. The tray and ink motors normally ...

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.
