Motion Control • Amplifiers

Motion control amplifiers change the power of a motion controller signal into a higher power voltage/electrical current and then present it to the actuator.

Amplifiers utilize an external energy force in order to increase a signal's power without altering the signal itself. For motion control applications, amplifiers take a motion controller's control signal, transform it, and then present it to the actuator. "Intelligent" amplifiers are capable of internally closing the velocity/position loops, which results in heightened control accuracy.
