Product Description:
The MSK070E-0300-NN-S1-UP1-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and velocity control in industrial automation, where compact size, integrated feedback, and high dynamic response are needed for gantries, packaging axes, and material-handling modules. In operation, the motor converts commanded current into rotary motion and works with a matching drive to maintain speed and position under changing load. That control behavior supports repeatable starts, stops, and short indexing moves in automated equipment. Its compact housing suits installations where axis space is limited but accurate motion is still required.
The unit relies on natural convection, so surrounding airflow must remove stator heat without external blowers. It uses a frame size 070, which provides a flange pattern and shaft height that match standard machine interfaces. Within that frame, the extended motor length E increases continuous torque capability while keeping the same mounting footprint. Electrical behavior follows winding code 0300, which sets phase resistance and inductance for rated current operation. Position feedback comes from an encoder with 128 signal periods per mechanical revolution, allowing fine interpolation for smooth servo operation and tight contouring.
Feedback data leave the housing over a Hiperface interface, combining absolute position words and incremental tracks in one cable to simplify wiring between the motor and drive. The underlying sensor uses an optical encoder design for stable accuracy across temperature changes, and its single-turn encoder structure provides one absolute revolution reference for applications that home between cycles. An electrically released brake provides 23 Nm of holding brake torque, helping vertical axes stay in place when power is removed. The shaft uses a keyway for positive torque transmission, and the feedback connector can rotate 240° to simplify cable routing in tight spaces. This arrangement also helps reduce separate wiring runs at the machine.
