Board turns a stepper into a servo 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, ...

(Image: PI miCos) Stability and Resolution of Closed-Loop Steppers Compared to Servo Motors Position-controlled stepper motor axes are recognized for outstanding position stability. Traditional ...

Quadrature encoders work inmany applications to determinedisplacement and direction of mechanicaltravel. They vary in design, butthey all do the same thing: supply a setof square waves 90° out of ...

Even removing the microcontroller and trying to work with the servo’s driver-IC and potentiometer from an Arduino Nano didn’t get him satisfaction.

Closed-loop stepper motors may be the best choice for tasks typically done by servos because traditional steppers couldn’t handle them.

[Part 1 begins with an overview of the operation of thyristor-fed DC motor drives. Part 2 continues with a look at converter output impedance, four-quadrant operation, single- and double-converter ...
