Product Description:

The MSK050C-0300-NN-S2-UP0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In a motion axis, it converts electrical energy from a drive controller into tightly regulated torque and speed for position-controlled tasks such as pick-and-place movement, tool handling, and indexing in automated lines. This operating role suits machinery that requires repeatable acceleration, accurate stopping, and stable speed control during frequent starts and stops. The model uses the 050 frame with C length, and its 0300 winding code is matched to medium-power drive stages often used in packaging, printing, and general handling equipment.

Thermal management relies on natural convection, so heat produced in the stator leaves the housing through ambient airflow without external fans or liquid circuits. The rotor and shaft are machined for increased concentricity, so radial runout stays low when the motor is coupled to precision gearboxes or directly to loads. A field-serviceable connector that is rotatable through 240° allows the feedback plug to be positioned for easier cable routing in crowded cabinets. Position data travel over the EnDat2.1 serial interface, and the measuring system delivers 2048 signal periods per mechanical revolution, permitting fine interpolation in the drive for smooth velocity control. These feedback and connector features support compact installations where cable direction and signal quality both matter.

The measuring system uses an Optical scanning principle to generate high-quality sinusoidal signals, and its single-turn design reports absolute shaft angle within one revolution without multi-turn tracking hardware. Because the motor ships without a holding brake, an external locking device or drive-applied torque is required if standstill security is needed. A shaft with a keyway provides positive torque transmission to pulleys or couplings and aligns with standard keyseat dimensions. This shaft style is useful where a keyed hub is preferred for transmitting load torque without slip.
