Servo motors Manufacturers online

Servo motors are electromechanical drives that are used to precisely control position, speed and torque.

They typically consist of an electric motor, a gearbox, a position sensor and control electronics.

Below you will find the structure and function of servo motors as well as an overview of their areas of application and their advantages:

Structure of servo motors:

A servo motor is made up of the following components:

1. An electric motor, usually a direct current (DC) or alternating current (AC) motor.
2. A gearbox which reduces the speed and increases the torque.
3. A position sensor: often a potentiometer or an optical encoder to detect the current position.
4. An electronic control unit that compares the actual position with the target position and adjusts accordingly.

How servo motors work:

1. A servomotor is controlled via pulse width modulation (PWM) or digital control.
2. The electronics receive signals, interpret them and adjust the motor movement to achieve the desired position.

Use of servo motors:

1. Industrial applications:
In automation technology, e.g. in CNC machines, robots and as drives in production lines.
Movement of gripper arms and positioning devices in conveyor technology.

2. Vehicle technology:
In vehicle electronics for steering and throttle control.
Steering control in cars and boats and for wing adjustments in airplanes.

3. Household appliances:
In kitchen appliances for positioning in coffee machines or automatic mixers.
Automatic door openers, blind movement or camera controls in smart home systems.

4. Consumer electronics:
For gimbal control for stabilized shots in camera and film technology.

5.Toy industry:
Motion control in interactive robots and remote-controlled vehicles

6. Medical technology:
Precision movements in surgical robots or prostheses

Advantages of servo motors:

• High precision and fast response time.
• Energy efficiency through targeted control.
• Compact design and high power density.
• Long service life with low maintenance requirements.

Servomotors are indispensable components in modern technology and industry. Their versatility and precision make them ideal for applications that require exact movements. With advanced control systems, servomotors will continue to play an important role in the future.

Below you will find an overview of the most important criteria to look out for when buying servo motors:

When buying servo motors, there are important factors to consider to ensure that the motor is suitable for the application in question.

• In order to purchase the right servo motor for the application, it is important to keep a close eye on the technical specifications.
• Determine the required torque (static/dynamic) and thus the required power of the motor.
• Check the maximum achievable speed for your application.
• Make sure that the operating voltage is compatible with your control system.
• Select a motor with efficient power consumption.
• The motor's moment of inertia is decisive for its dynamics and precision
• The motor must fit mechanically into the intended system.
• Determine the feedback system suitable for your needs: incremental or absolute encoder for precise position detection.
• Check compatibility with fieldbuses such as CANopen, EtherCAT, Profibus or Modbus.
• Determine the appropriate level of controllability for speed, torque or position control.
• Ensure that any existing control system can optimally control the motor.
• Determine the type of shaft required for the connection to the downstream mechanics: smooth shaft, feather key or splines.
• High-quality bearings extend the service life and reduce maintenance costs.
• Ensure that the motor is suitable for the operating conditions. If the motor operates in harsh environments, protective measures are required.
• Vibration & shock resistance are important factors in dynamic or mobile applications.
• Observe the required protection class (IP protection) depending on the operating environment (e.g. IP65 for industrial applications).
• Pay attention to the manufacturer's certifications: CE, UL, ISO 9001 or special industry certificates for automotive, medical technology or aviation.
• The supply of spare parts and technical support are important for industrial applications.
• Compare the purchase costs with the operating costs: an energy-efficient motor can be cheaper in the long term.
• Give preference to maintenance-free or low-maintenance motors. Quality and features should match the budget.
• Check whether the manufacturer offers maintenance packages or extended warranties.
• Bear in mind that standard models are often available more quickly than customized solutions.
• Long delivery times can delay the production process. If there is a regular need, strategic stockpiling can make sense.
• If special shaft shapes, additional sensors or special protective coatings are required, the supplier should be able to provide these.
• Also look out for brakes, emergency stop functions or redundant feedback systems for critical applications.

When purchasing servo motors, numerous technical, economic and logistical aspects must be taken into account. Close coordination with manufacturers and suppliers as well as a thorough requirements analysis help to find the optimum solution for the respective application.

Servo motors can be purchased from various suppliers. Comprehensive information about manufacturers and suppliers of Servo motors from all over the world can be found on Exportpages.
