Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on ...

Figure 3-5: Stepper motor control circuit. This project uses the ULN2803 octal high-voltage, high-current Darlington array to switch the stepper coils. This chip is readily available for around $0.75 ...

Stepper motors are useful in many consumer, industrial, and military applications. Some, such as personal-transportation systems, require precise speed control. Stepper-motor controllers can be simple ...

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.

All control is via UDP over ethernet, and again the basic functionality is there, but some niceties such as motor synchronisation and state querying are again subject to further releases.

Over the last 2 years [Carl Bujega] has made a name for himself with his PCB motor designs. His latest adventure is to turn it into a stepper motor by adding position control with microstepping. Th… ...

Toshiba has launched an 4 x 4mm QFN24 stepper motor driver that can run from 4.5 to 33V and deliver up to 1.2A. Typical on-resistance of the output block is 1.2Ω. “It is well suited for ...
