Servo motors have undergone rapid technological advancements in the last decade or so. These include improvements in motion control technology, computing power, electrical circuits, induction systems and networking, resulting in pin point precision, better speed and reduced costs. This article explains how these technological developments have affected these important industrial components.

Technological advancements in servo motors have resulted in improved precision and speed control. Servo motors have been widely used in fields of motion control technology and computing power. New models feature advanced machines like closed loop stepper systems that use a more efficient and reliable process. Digital controlling systems on these machines ensure better accuracy while corresponding well to the traditional operation. Higher torque and reduced costs are two other major benefits.

Torque values in the machines of today are much higher than the standard servo motors. These machines can produce more push or pull force. High torque models are matched by the high voltage circuits. Power efficiency in these servo motors ...
... is essential in the closed loop system. The closed loop circuitry draws as much power as is necessary for the application, meaning that a full current is not wasted on a low power target.

Most new models of servo motors also provide faster speeds and more precise turning capabilities. Factor in the second per degree rating when comparing new and old designs as it provides vital information about the time it takes the machine to turn to a particular angle. Rapid models designed for use in robotics and propellers can turn at speeds as fast as 0.06 seconds per sixty degrees.

The servo motors today have improved rotary and linear electrical circuits, permanent magnet and induction systems and digital signal controllers. Rotary machines use high resolution serial encoder feedback to automatically program the settings. These machines produce more accurate results while minimizing electrical noise and ensuring full internal error checking.

Vast improvements in computing power is regarded by many to be the most significant contribution to servo motor technology. Deploying fast processors in PC-based controllers has made it possible to update multiple servo control loops while handling machine control logic. For mechanisms using multiple servo motors, only the path of one of the motions has to be programmed in place of writing code for the motion of each individual motor. This abstraction provides faster development of complex mechanisms.

These PC-based controllers have open architecture paired with intelligent software which offers standardized programming tools. These tools facilitate easier implementation of control routines and provide advanced preprogrammed routines though software libraries.

Networking advances allow servomotors to coordinate their activities in a more efficient way. For instance, a network with distributed clock technology would have the control needed by demanding CNC applications.

These advances have significantly brought down the cost of ownership and, at the same time, increased accuracy and efficiency. The focus is on raising the final productivity and operational efficiency.

Along with procuring top-of-the-line equipment for a facility, you also need to partner with a reliable repair provider. Servo motors and other components work under extreme pressure in a facility, so it is only natural that they will malfunction far down the road. You will need to call in a repair company to get the malfunctioning components repaired quickly. Whether it is Allen Bradley, Fanuc, Indramat or Yaskawa, they will be able to provide you with flawless work and have you back up and running in no time.
