Rated Voltage vs. Power Supply Voltage Perhaps one of the biggest points of confusion is the discrepancy between the coil voltage listed on a stepper motor’s datasheet and the usually much ...

Most stepper motor driver ICs rely on the inductive nature of the stepper motor windings to implement PWM current regulation. Using an H-bridge arrangement of power MOSFETs for each winding, the ...

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.

While that motor was well suited, [Clough42] picked a significantly lower-cost servo motor from China which he dubbed the “Stepper Killer Killer”.

The only physical connectivity, beside the motor, are ethernet and a power supply via the user friendly XT30 connector.

With the SC2818, Nanotec presents a stepper motor with a flange size of 28 mm and a torque of up to 0.22 Nm.

Nikon Corp., the world's No. 2 chip stepper maker, said on Thursday it has won a contract to supply Taiwan's Powerchip Semiconductor Corp. with equipment used to make NAND flash memory chips.

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Driving a stepper motor that has a very short electrical time constant from a high voltage supply can result in current distortion as shown in Fig. 3 upper panel.

Returning to the non-isolated power supplies in question, also like the DC-51, there does not appear to be any emc filtering whatever on the mains input nor the output to the motor – a situation which ...
