The servo motor is most often employed in high-tech industrial equipment like automation technologies. It is a self-contained electrical apparatus that rotates machine parts precisely and efficiently. This motor’s output shaft can be positioned at a specific angle. The majority of Servo U.S Motors are found in household electronics, toys, automobiles, and aircraft.  

Control Methods High performance and maximum flexibility are paired with servo drives and servo U.S Motors .

The servo drives can take control of the automation system through an inbuilt motion controller, or they can link to a variety of motion controllers through I/O or specific communication networks like EtherCAT. 

A broad family of AC brushless servo motors with exceptional performance is known as Unimotor. Unimotor delivers the ideal match for each application demand with a wide torque range, from 0.72 Nm up to 136 Nm, rated speeds from 1000 rpm to 6000 rpm, multiple inertia levels, and a large selection of feedback options. Added versatility is offered by different mounting configurations and a single cable choice, and the utmost user-friendliness is provided by drive integration with an electronic nameplate. 

U.S Motors categorize servo drives and motors based on the duty needed for the application in order to maximize performance .

High-dynamic applications needing rapid accelerations and decelerations are known as pulse duty. Pick-and-place, flying shear, and other cut-to-length devices are examples. These applications show high peak torque (for example, 300% overload) and modest RMS torque. 

Low acceleration and acceleration rates are necessary for continuous duty, which involves high precision over a long time. Printing, winding, and labelling are among the examples. These applications include a high RMS torque and a moderate peak torque. 

Broad Servo U.S Motor classification  

Based on their intended use, Servo U.S Motors are divided into a variety of categories, including AC and DC servo motors, brushless DC servo motors, positional rotation, continuous rotation, and linear servo motors. Servo motors typically have three wires: power, ground, and control. These motors’ sizes and shapes vary depending on their intended use. Due to their simplicity, affordability, and dependable microprocessor control, RC servo motors are the most popular type of servo motor used in robotics and hobby applications. 

  • Servo AC Motor 

An AC servo motor, also known as an AC motor with an encoder, is used with controllers to provide closed-loop feedback and control. This motor can be positioned with great accuracy and precisely controlled as needed for the applications. These motors often have better bearings or higher tolerance designs, and some simple versions even employ higher voltages to provide more torque. Automation, robotics, CNC equipment, and other applications requiring a high degree of accuracy and necessary adaptability are the principal uses of an AC motor. 

A wide selection of servo motors is available from AC Servo Motors Control Techniques in many configurations to suit your needs. 

The Digitax HD servo drive series is perfect for use with the Unimotor hd, a highly dynamic brushless AC servo motor range. The drive provides open-loop control of both induction and permanent magnet motors in addition to full servo control. 

Numerous design and feedback options are available for the Unimotor fm medium inertia motor family. 

For dynamic applications, the revolutionary motor design of NT motor offers a small footprint, great torque, and low inertia. 


  • Servo DC Motor 

In the realm of winding & armature winding, a DC supply is often independent of the motor used as a DC servo motor. Either the field current or the armature current can be controlled to archive the control. Field control has a few advantages over armature control in particular. Like field control, armature control has several advantages over the latter. The DC servo motor should be controlled based on the applications. Due to the low armature inductive reactance, DC servo motors respond to start or stop command signals quickly and with great accuracy. Similar equipment and computer numerically controlled machines employ DC servo motors. 

Typically used in situations where precise control is needed but an AC power source is not required. For example: 

  • Robotic arms
  • AGV wheels
  • Industrial automation equipment
  • Printers
  • Indexers
  • Any equipment that is needed to perform tasks with accuracy and precision.

Since many DC servo U.S Motors have feedback options, mounting options, shaft variants, custom windings, and interaction with Nidec Motion gearing systems, they may be customized to meet a wide range of performance requirements.  

The LD Series DC servo U.S Motors provide several connector types, an IP65 rating, a torque range of 1.45 Nm to 10.2 Nm, and rated speeds of 1000 to 6000 rpm. The LD Series Servo U.S Motor Guide has more details about the LD Series servo motors.
