Many applications require drive solutions that have a central opening through which, e.g., light, cables or parts of the application can be guided. Examples of this can be found in optics and photonics for laser steering systems or in automation and robotics for semiconductor handling systems. Until now, conventional systems always resulted in compromises here. […]
Stepper Motors
Comparing three types of stepper and servomotor power supplies
In a recent online article, Teknic engineers have outlined how dc-powered motion-control applications differ from most other dc-powered designs … and how the motors in these applications need specialty power supplies. The article focuses on dc power supplies, which are the most common and suitable for fractional-horsepower motors. What makes dc motion-control applications unique are their […]
Four axis stepper controller for automation applications
One of the latest products to be released by Allmotion is their EZ4Axis23WV stepper motor controller driver, which runs four fully independent stepper motors using fully intelligent stepper motor controller circuitry. This four-axis position controller with power drivers features programmable acceleration ramps and speeds using four independent 1 Amp (2 Amp peak) PWM chopper drives. […]
Motion-control systems help automate COVID-19 testing
Automated biochemical analyzers vastly accelerate the testing of patient samples in laboratories, which has become critical now that the COVID-19 pandemic has spread across the globe. Advanced automation with motor-based motion systems will help in the fight to hasten diagnosis. Just consider the cobas 6800 and 8800 machines from Roche that automate testing of nasopharyngeal […]

MOONS project astronomers use motion technology from FAULHABER
When it comes to exploring our disc-shaped spiral galaxy, astronomers have a fundamental problem: Earth is located on the disc of the Milky Way, which obstructs the view of the galaxy’s center (and its other side) with countless stars. So determining where on the disc other celestial bodies are located is difficult to impossible from […]
What is a constant voltage drive for a stepper motor and when is it used?
There are two fundamental types of stepper motor drives: constant voltage drives, which supply a fixed voltage to the motor, and constant current drives, which manipulate voltage to ensure that a constant current is delivered to the motor. Stepper motor electrical basics The most fundamental equation governing the behavior of a stepper motor is Ohm’s law, […]
New harmonic gearing on 1.8° flat PKP series stepper motors from Oriental Motor
Oriental Motor now sells a new PKP Series stepper motor. The offering includes a 51-mm (2.0-in.) frame size harmonic gearhead for the 42-mm (1.65-in.) PKP Series 2-phase Flat Type motor. This new combination compliments the 60 mm (2.36 in.) PKP Series Flat Type which is available with a Harmonic gearhead or round shaft. Both frame […]
