This month, NASA will be sending its fifth rover to Mars. Its main mission is to collect soil samples that will be analyzed on Earth at a later time. The rover will also carry a helicopter that will perform the first flights on the Red Planet. maxon’s precision dc and brushless dc motors will be […]
WITTENSTEIN releases new NPL-W corrosion-resistant gearbox
WITTENSTEIN alpha, a provider of high-precision servo gearboxes and drive systems, has launched a new corrosion resistant gearbox to support the increasing market demand for components that can withstand processing, overspray and cleaning environments. Ideal for food processing, bottling and packaging machines, NPL-W features a painted, corrosion resistant housing with no gaps, depressions, undercuts, dead […]
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. […]
High-power 10-pole brushless motors from Koford Engineering
Now Koford Engineering sells two new 10-pole motors. These high-performance motors are 5.07-in. (129-mm) brushless motors with no-load speeds to: • 2,866 rpm at 24 V • 5,760 rpm at 48 V Both hall sensor and sensorless versions are available. Winding temperature sensors are offered. Peak power is 2,502 watts for the 48-Volt unit and […]
ABB’s new AC motors offer power-dense, water cooled design
ABB’s AXW 5000 and 5800 motors offer more horsepower per pound than conventional totally enclosed fan cooled (TEFC) motors but with a smaller frame size. This helps save space, up to 8 in. in overall length in some cases, which enables more compact installations. Advantages of AXW motors include higher power densities, smaller overall footprint […]
Flat motor series from FAULHABER now features integrated gearhead, encoder
FAULHABER has extended its BXT flat motor series by adding corresponding gearheads and integrated encoders as well as speed controllers that are also exceptionally short in the axial direction. All components have been optimised to ensure that they function perfectly together. There are three different sizes available than can solve many different drive challenges. In […]
What’s the difference between torque mode and velocity mode in servo control?
Servo systems are used when the application calls for precise control of position, velocity, or torque — or a combination of the three. Depending on the parameter being controlled, the servo system can be operated in torque mode, velocity mode, or position mode. Each mode requires control loops that allow the servo drive and controller […]
What is direct torque control (DTC) for AC induction motors?
Variable frequency drives control AC induction motors through one of several control schemes. Scalar control (also referred to as V/Hz or V/f control) varies both the voltage and frequency of power supplied to the motor to maintain a fixed ratio between the two. This keeps the strength of the magnetic field at a constant level […]
Portescap motors support critical-care applications during COVID-19 pandemic
The COVID-19 pandemic is creating an urgent need for critical-care equipment such as ventilators and infusion systems — as well as increased demand for lab analyzers. Portescap has been a leading expert in miniature motors and precision motion control solutions for medical devices and clinical diagnostics for many decades and is proud to be able […]
Improving performance without machine redesign
Improving machine performance to meet market demands doesn’t have to mean starting over from scratch. By partnering with a motion-centric supplier that offers new-generation motion systems plus co-engineering expertise to provide perfect-fit customizations, aging machines can be brought back to life with minimal design impact. As new technologies enter the industrial market, engineers must find […]
