Industrial robots achieve their high accuracy often through servo motors.. These advanced drive systems control position, speed, and acceleration precisely and consist of a motor, sensor (encoder), and control within a closed loop. For example, packaging machines position products with ±0.5 mm accuracy. A servo motor is a control system for precise motion control.
The function of such a servo motor is based on feedback: The control compares actual position with desired position and corrects deviations, often via PWM. For example, CNC machines utilize this for micrometer-precise tool guidance. The primary applications for a servo motor are robotics and automation. The requirements for these drives are diverse, which drive solution manufacturers must consider.Optimize the mechanics and encoder technology
Simple potentiometers are often unsuitable for industrial precision drives, like those commonly used in a servo motor due to mechanical wear and limited accuracy, despite their low cost. For example, after millions of cycles they may exhibit signal noise. Advanced systems, especially in high-quality servo motors., utilize robust optical/magnetic encoders or resolvers. Absolute encoders capture the position even after a power failure, saving reference runs – important for gear box developments for such drives.. The choice of feedback system, e.g., for zero-backlash planetary gearboxes, determines the system performance and reliability of each servo motor.Compare motor variants and make informed decisions.
The choice between a servo motor servo motor and a stepper motor is application-specific. Stepper motors are cheaper and suited for applications with defined loads and low dynamics, e.g., in 3D printers. For example, a stepper motor can lose steps under overload; a servo system, like one offered by ATEK, prevents this through its control loop. servo motor bietet, verhindert dies durch seinen Regelkreis. Controlled servo drives offer higher performance and constant torque over wide speed ranges. Ein A servo-ready gear motor system with planetary gearbox is often a suitable solution for demanding servo motor-applications.
- The choice of motor type (servo motor or stepper motor) is highly dependent on the specific application.
- Stepper motors are suitable for cost-sensitive applications with defined loads and lower dynamics but carry the risk of losing steps, which is not the case with a servo motor servo drive.
- Servo drives, which form the core of every servo motor, offer higher performance, constant torque, and avoid step losses through their control loop.Industrial applications are dominated by brushless AC (synchronous) and DC-

Industriell dominieren bürstenlose AC- (Synchron) und DC-servo motors. (EC motors) due to their low maintenance and high power density. For example, in robotics, brushless AC designs of a servo motor are widely used due to their power density. The choice of motor type – whether for compact inline drives or integrated CNC drives, which often rely on a servo motor – depends on performance and application.Successfully design control and integration
The servo controller (servo amplifier) is the central control component for a servo motor, converting the desired value commands from a PLC into precise motor currents. For example, modern controllers, like those offered by ATEK, provide autotuning and fast communication via EtherCAT (cycle <1ms), simplifying the commissioning of a servo motor system. Integrated drives (servo motor, encoder, controller in one unit) reduce wiring and space requirements. For example, in modular machines, they can reduce installation times by up to 30%. Efficient control algorithms and compact, networked drives with digital interfaces as well as servo gear motor systems with fieldbus optimize the system integration of the servo motor.Optimize drive design and operation
The correct selection of a servo motor requires precise determination of torque, speed, and load inertia. For example, an underestimation of the inertia in a 5 kg handling task can lead to control oscillations in the servo motorsystem. Careful, software-supported design is crucial for optimal performance of a servo motor.
- A precise determination of torque, speed, and load inertia is the foundation of the servo motorselection.
- Software-supported design helps ensure optimal performance of the servo motor and avoid errors.
- Environmental conditions such as temperature, humidity, and required protection class (e.g., IP65) are critical selection criteria for the servo motor.
- The required accuracy and the appropriate feedback system (e.g., absolute encoder) for the servo motor must be specified.
