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 ...

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.

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 ...

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.
