Servo Motors

Servo motors, also called “Servos”, have many uses within motion control. These motors utilise rare earth permanent magnet technology to generate high magnetic fields. They have multiple coils, commonly referred to as Poles, and by controlling the voltage and current in these coils, we can produce precise motion. The motors have high resolution feedback devices (known as a rotary encoder), which when used with the latest digital electronic servo drives allow very accurate control of the motors speed, position and torque.

This makes the Servo motor highly diverse, they are power-dense, smooth running and often small making them well suited to a range of applications. They can be described as rotary actuators which allow for precise control of angular position.

The range of servo motors we have available suit a wide range of environments including wash-down, extremes of temperature, ATEX explosion-proof environments and many others.

Servo Motors are typically used on a very diverse range of applications across many different industries and we have been supplying in these for many years solving a vast amount of applications.

Servo motors are used extensively within the factory environment but are also commonplace in applications such as robots, toys, vehicles and home electronics.

Typical applications using Servo Motor include.

Simulation Applications – The desired features for simulation applications include speed, torque and smoothness which makes servo motors a fantastic choice for this industry.

Robotics Applications – Servo motors are light weight and small these attributes suit this industry extremely well.

Test and Measurement – These applications require accuracy for speed, positioning or force for replication of tests or simulation of events and the servo motor is ideally suited to this.

Defence – Servo motors are exposed to harsh environments in defence applications, these include high temperatures and high shock loads so it important that the servo motor can withstand these.

Subsea and Oil & Gas – In oil and gas applications, servo motors are often exposed to high pressures and high temperatures and sometimes explosive environments. 

Machine Tools – Machine tool applications are another example of applications where high accuracy is required and servo motors are selected.

Conveyer and Handling Systems – This type of application required high speed, high accuracy, and torque especially when indexing or positioning is needed.

Food and Beverage – We have a range of servo motors which are suitable for use the food zone, where hygiene, washdown and constant temperature changes need to be considered.

Printing Press – Servo motors are often selected for applications in printing press for their high accuracy and speed.

Servo motors have many advantages and are often selected for the following reasons.

• High accuracy
• High efficiency
• High reliability
• High acceleration
• Suitable for harsh environments
• Smooth running
• High ratio of torque to inertia
• Various sizes available
• Quiet operation
• High torque at low speed
• Closed-loop control

Our range of servo motors can be seen above, they come from our suppliers Kollmorgen and ABB.

With a wide range of motors featuring different encoder types plus options such as holding brakes, mechanical fitting and environmental protection, our servo motors can cover any application including extreme environments.
