You definitely need a tight connection for controlling a stepper/servo in real time. This is why most motion controllers are in close proximity to the actual driver (open or closed loop) electronics.

All you need to test a stepper driver is a clock signal to the step input. Oh and powering the thing up too. A 555 timer circuit does just fine.

Understanding bipolar stepper motors will give engineers the confidence they need when selecting a driver. Even veteran engineers often suffer from a lot of misconceptions about stepper motors and ...

These resistors are physically large and quite expensive – two of these resistors can cost as much as the driver IC! The MP6500 stepper driver IC. The MP6500 bipolar stepper motor driver with internal ...

Select a stepper driver based on that number. Tips 1 and 2 courtesy of David Goodin, AllMotion Inc. Be aware of torque issues. Torque is often at the root of many stepper-related issues.

Haydon Kerk Motion Solutions, Inc., a premier manufacturer of engineered linear motion products, announces the addition of stepper motor drivers available for 24 hour shipment ...

The α STEP 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 ...

Based on the Motorola (now Freescale) heavily used but obsolete SAA1042 stepper-motor-driver IC, this Design Idea describes a CPLD (complex-programmable-logic-device)-based implementation of a stepper ...

For applications where the microprocessor is overburdened or absent, the SLA7051M constant-current, two-phase unipolar stepper motor driver includes a built-in translator, allowing ...

In many printers, the stepper drivers can be changed as they are fitted as ‘Pololu’ carrier boards or ‘stepsticks‘ – small pcbs that plug into the main printer pcb through two rows of header pins.
