A motor-drive servo amplifier's output voltage has a fundamental frequency and amplitude that corresponds to the motor speed, torque, and number of motor poles. PWM amplifiers, by their nature, also ...

Motor power cables don’t just couple noise currents into adjacent cables: they inject unwanted noise currents into all conducting surfaces, including the machine frame. Machine-frame currents travel ...

Controlling machine resonance—the “white noise” generated by machine motion—in servo-driven printing and converting machines is a crucial motion control challenge. Discover how Rexroth intelligent ...

Danfoss Power Solutions has released the Vickers PVMX axial piston pump, featuring 3,800 rpm operation, 350 bar pressure ...
