Grund sind mechanische Eigenschwingungen des Servomotors. Basierend auf Messungen der strukturmechanischen Eigenschaften von Servomotoren wird ein allgemeingültiges Modell abgeleitet. Der Einfluss der Schwingungen auf die Bandbreite von Servoantrieben wird systematisch untersucht und durch Messungen verifiziert. N2 - The dynamic improvement of the current controller due to the usage of wide-bandgap semiconductors cannot be transferred to the speed controller of a servo drive. The rea-son are structural mechanical resonances of the servo motors. Based on the measurements of the structural mechanical characteristics of servo motors a generalized model is derived. The influence of these resonances on the control loop of servo drives is systematically analyzed and verified by measurements at several test stands.

As the motor current is proportional to torque or force, the current control loop dynamics is crucial for all operating modes. In production machines used in the semiconductor industry, it is particularly important that the bandwidths of the control loops are continuously increased. It is thus important to take the dependency of motor resistance and inductance on frequency in control loop design into consideration. As the switching frequencies of wide-bandgap semiconductors increase, the effect becomes even more significant. This paper discusses the influence of frequency-dependent resistance and inductance on the behavior of a PI current controller. A design method for an optimized and robust current controller is then presented on this basis. Verification is performed with two completely different servo motors-a 3-phase permanent magnet synchronous motor and a high-dynamic optimized voice-coil motor.
