Stepper Motors

Stepper motors are DC motors that move in steps. Having computer-controlled stepping means you can get very precise positioning and speed control. As stepper motors have precise repeatable steps they are ideal for applications that require precise positioning. Normal DC motors don't have much torque at low speeds but a stepper motor features maximum torque at low speeds.

Types of Stepper Motors

Bipolar Stepper Motor

Bipolar Stepper Motors contain an onboard driver that uses an H bridge circuit to reverse the current flow through the phases. Bipolar motors are generally better than unipolar motors. They have more torque and are more efficient. Bipolar stepper motors use electromagnetic coils which are energized on command, to turn a shaft. Using this system, the shaft can be turned in measured movements, and can also be reversed.

Hybrid Stepper Motor

Hybrid Stepper Motors allow for yet more precision, through techniques such as half-stepping and micro-stepping. Microstepping is a way of increasing the fixed number of steps within a motor by programming a driver to send an alternating sine/cosine waveform to the coils. Hybrid stepper motors combine aspects of both permanent magnet (PM) and variable reluctance (VR) stepper motors.

Permanent Magnet Stepper Motor

Permanent Magnet Stepper Motor has a rotor that is made from two permanent magnet rotors which are slightly offset from each other. It’s an electromechanical energy conversion device, which converts electrical energy to mechanical energy.

Applications

3D Printers
CNC
Camera Platforms
Robotics
Process Automation
