high power loads using low-level voltage signals A common automation system requirement is to drive or actuate high power loads using low-level voltage signals. Motors, solenoids, relays and capacitive loads can be actuated with appropriate circuitry that is only possible using small current/...
Description of Pulse Width Modulation

Description of Pulse Width Modulation blog post

Post date: 10 years 9 months ago
PWM (Pulse Width Modulation) refers to the concept of rapidly pulsing a digital signal on a wire. Along with many other uses, it can be used to simulate a varying static voltage. PWM is commonly used for driving motors, heaters, LEDs or lights in varying intensities or speeds. TERMINOLOGY Period...
Back-EMF Motion Control Feedback

All About Back-EMF Motion Control

Post date: 11 years 1 month ago
ElectroMotive Force Electromotive force (EMF) refers to the voltage generated by a spinning motor. Measuring this voltage in order to determine the rotational speed of a motor is commonly called Back-EMF since the voltage tends to "push-back" against the circuit driving current into a motor's...
