[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

National Instruments (Nasdaq:NATI) today announced the latest version of the NI SoftMotion Development Module for LabVIEW, the revolutionary software that empowers machine builders and original ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

As the shift to automation continues to gain momentum in the industrial sector, servo motors and stepper motors with electric actuators become ever more important. When selecting a motor for an ...

Motor controllers in general and especially closed-loop controllers have come a very long way in the past few years. Control flexibility, adaptability, and strategies that were only dreamed of or very ...

Sensorless control of stepper motors, in which the speed of the rotor is determined through a virtual encoder within the controller, is possible, claims German firm Nanotec. “This enables the stepper ...

Trinamic Motion Control claims to be making the “smallest single-axis servo controller-driver module with integrated motion control”. TMCM-1321, as it is known, controls two-phase bipolar stepper ...

Stepper and servo motors have different attributes when considered for motion applications. Torque curves play an important role in selecting the proper size and type of motor for an application.
