Servomotor

Servomotor

The servomotor is an electrical motor. Together with a servo amplifier the servomotor forms a servo drive. The servomotor is operated in a closed control loop with position, torque or speed control.
The terminals ELM72xx support control of permanent magnet synchronous motors. These consist of 3 coils which are offset by 120° and a permanent magnet rotor.

Servomotors particularly demonstrate their advantages in highly dynamic and precise positioning applications:

• very high positioning accuracy in applications where maximum precision is required through integrated position feedback
• high efficiency and high acceleration capacity
• servomotors are overload-proof and therefore have far greater dynamics than stepper motors, for example.
• load-independent high torque right up to the higher speed ranges
• maintenance requirements reduced to a minimum
