Applications

The Rexroth MSK series permanent magnet synchronous servo motors are used in precision motion control systems across industrial automation, machine tool, robotics, and packaging machinery applications. They are designed to pair with Rexroth IndraDrive servo drives (such as the HCS and HMS series) and are common in CNC machining centers, injection molding machines, printing presses, and automated assembly equipment. The Wittenstein Alpha TP series inline planetary gearbox is a high-precision, low-backlash reducer widely used where high gear ratios and compact inline form factors are required — such as rotary indexing tables, conveyor drives, and servo-driven axis assemblies. The 220:1 ratio of this gearbox makes it particularly suited to slow-speed, high-torque output applications where the motor runs at its efficient speed range. This combination is common in European-made industrial automation machinery from the 2000s and 2010s, and Rexroth IndraDyn S components of this generation remain widely supported by IndraDrive servo amplifier systems in active production environments today.
