The circuit in this Design Idea drives low-power, unipolar stepper motors using only a shift register, a few resistors, and low-power transistors. Adding an inexpensive 4053 analog switch allows ...

Microcontrollers may dominate today’s stepper motor projects, but there’s a charm in driving them with pure CMOS logic. Try ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Part 2 in a series of articles on motor control design focuses on how to reduce noise, one of the biggest challenges, in stepper motors. The amount of noise in a motor depends on the type of motor, ...
