Reliable and compact servo motor drives

Motor drives transform the control signal from the motion controller into electrical energy that is provided to servo motors. Newer intelligent motor drives can close the position and velocity loops internally leading to a more accurate and more powerful motor control.

Infineon’s chip and integration technology enables the motor drives to leave the external cabinet and connect directly to the motors within each individual axis of the robot. Instead of having 3-phase supplies for individual motors only a common DC-bus connection is required. By also integrating a power line communication solution, even a separate communication bus could be avoided.

Within a moving robot-arm the wiring efforts can be reduced from 27+ down to two.

Below we would like to recommend the Infineon components for an efficient compact servo motor drive:
