Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

Typical stepper-motor control circuits use either logic gates and flip-flops or shift registers to generate the proper sequences of binary codes that produce bidirectional stepper-motor movement. A ...

The FTDI DLP-USB245M is a USB-to FIFO interface module that simplifies the control of multiple steppers by a PC.

Due to this fine level of control, stepper motors are required in any applications where there needs to be an exact movement such as 3D printers and CNC machines (or robots).

Programming very complicated stepper movements then becomes just a matter of generating the right “audio” file and playing it out. [lhartmann] demonstrated this earlier with an Orange Pi.

Stepper motors are well known for their ability to perform accurate positioning in an open-loop mode. But they have a reputation for generating a lot of heat when rotating at high speeds ...

If you are [Tech Build] you go all MacGyver on an old printer and pull out a stepper motor. How does a stepper motor turn into an encoder? Well, that’s the MacGyver part.

The CMMS-ST single-axis position controller combined with the EMMS-ST stepper motor is designed as a comprehensive, easy-to-use package for single and multiple-axis handling with loads of up to 20kg.

Sensorless control of stepper motors, in which the speed of the rotor is determined through a virtual encoder within the controller, is possible, claims German firm Nanotec. “This enables the stepper ...
