Top Servo Drive & Motor Manufacturers
In manufacturing, precision and accuracy are key factors that can make or break a product. This is where servo motors and drives are essential in operating machines and equipment.
This article will review major servo drive and motor manufacturers, exploring their products, technology, and history.
What Is a Servo Motor?
A servo motor is an electric motor used for precise and accurate motion control. A feedback system helps it to maintain a specific position, torque, or speed.
Offering high strength for their size, servo motors are convenient and useful because they have built-in control circuitry.
What Is a Servo Drive?
A servo drive is an electronic device that controls the operation of a servo motor. It provides power to the motor and uses feedback signals to adjust the motor's speed and position.
Servo motors and servo drives work together to control the movement and speed of machinery, providing the necessary accuracy and consistency for manufacturing.

One of the newer companies on our list, FANUC, was founded in 1972. It's known as the world's largest supplier of industrial robots, but it also offers a robust line of servo motors and servo drives.
FANUC's servo motors include the A06B-0227-B300, which features a tapered shaft, and the A06B-0075-B303, which has a motor taper brake. The company offers servo drives like the A06B-6089-H105, a 3-phase device well-suited for CNC applications.
Founded in 1903, Allen-Bradley is now a brand owned by Rockwell Automation. The original company pioneered resistors and PLCs and became an important name among servo drive manufacturers. Allen-Bradley servo drives are designed for the most demanding industrial applications.
With a history spanning more than 170 years, Siemens is a global technology company. Siemens' servo drives are used in many diverse industrial applications, including CNC machining.
The company's offerings include the 6SL3120-1TE21-0AA4, a 3-phase, single-motor module. It's part of the Sinamics S120 Series. There's also the 6SL3120-1TE13-0AD0, a servo drive that replaced the 6SL3120-1TE13-0AA4.
6. Control Techniques
Control Techniques was founded in 1973 as KTK to design an innovative new drive. It re-branded as Control Techniques in 1985 and is now a brand of NIDEC Corporation.
Control Techniques servo drives include the DST1401P, which peaks at 4.5 amps.
7. Teijin Seiki
Japan's Teijin Seiki Co., LTD and Nabco Co., LTD merged in 2003 to form the Nabtesco Corporation. Teijin Seiki servo drives are still prized for their precision and control.
Examples include the ARS135-25, which operates at 200-230 V.
Founded in 1958, Indramat is now part of Bosch Rexroth. Its line includes the DKC06.3-016-7-FW, a 3-phase servo drive.
Frequently Asked Questions About Servo Drives and Servo Motors
Industrial Automation Co. is proud to provide products from the top servo drive and motor manufacturers. Read on to learn more about these essential industrial devices.
What Is a Servo System?
A servo system is a closed-loop control system that uses feedback from sensors to control a servo motor's position, velocity, and acceleration. Besides the motor, the system typically includes a servo drive and sensors such as encoders or resolvers.
What Are the Different Types of Servo Motors?
Servo motor manufacturers typically make two distinct types: AC servo motors and DC servo motors.
What Are the Advantages of AC Servo Motors?
AC servo motors offer a wide range of benefits, including:
- High accuracy and precision
- Fast response times
- High torque density
- Low rotor inertia
What Are the Advantages of DC Servo Motors?
DC servo motors deliver an array of valuable benefits, such as:
- High torque at low speeds
- Wide speed range
- Ease of use
- Energy efficiency
What Is the Difference Between a Stepper Motor and a Servo Motor?
Stepper motors move in fixed steps, while servo motors move smoothly and continuously. Servo motors generally are more precise and accurate than stepper motors.
What Are the Different Kinds of Servo Drives?
Regardless of the servo drive manufacturer, the main servo drives are analog and digital.
