Stepper Motor Controllers & Indexers

Stepper Motor Controllers are current amplifiers that turn a low-current control signal into a higher-current signal to drive stepper motors. They run using a type of open-loop system that takes digital step and direction inputs by a programmable pulse generator known as an indexer. In other words, Indexers take a signal from a computer or any other control device and turn them into pulses. Drivers or Stepper Motor Controls take these pulses and transfer them into a current (motion, steps, torque, speed) so the stepper motor can move accordingly. A user is able to operate and control steps using an interface.



Types of stepper drivers



There are many types of stepper drivers, including PWM/chopper drivers, L/R drivers and recirculating chopper drivers. The two most common are bipolar and unipolar drivers.
Bipolar drives have a single winding with two leads per phase. The winding has a current that needs to be reversed so that magnetic poles can also be reversed in the correct order.
Unipolar drivers have one winding with a centre tap per phase. This means that the magnetic pole can be reversed without switching the direction of a current, so a single transistor can be used per each individual winding.


What are stepper drivers used for?



Stepper drivers typical applications are current amplifiers in stepper motors. However, they can also be used for any device that operates at more than 50–100 mA.
