Product Description:

The MSK101E-0300-NN-M1-BP3-NNNN is a synchronous servomotor in the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It converts electrical energy into controlled rotary motion for positioning and cyclic drives in industrial automation. The motor is intended for direct pairing with digital controllers used on packaging lines, transfer systems, and articulated robots where precise torque and speed regulation are required. Its synchronous design supports repeatable motion on axes that must accelerate, run steadily, and stop with good control.

The motor dissipates heat through natural convection, a passive cooling method that relies on ambient airflow and eliminates additional fans or liquid circuits. Its feedback system uses a Hiperface interface that combines position data and electronic motor data over a single pair of conductors, which simplifies cabling between the encoder and controller. Position measurement is provided by an optical scanning unit that reads two-track code disks and yields 128 signal periods per revolution. Power terminals are arranged on the B-side, which helps keep machine wiring on one face of the installation. A keyed shaft provides positive mechanical coupling with standard transmission elements.

For axis homing and extended downtime positioning, the encoder stores its count over power loss; it is a multi-turn absolute encoder that tracks multiple revolutions without external batteries. During a machine stop, an electrically released holding brake supplies 120 Nm of static torque to lock the shaft. The motor uses frame size 101 with length code E, giving it the housing envelope assigned to that MSK size. This format keeps mounting geometry consistent within the same motor class while allowing the 0300 winding to be used in the assigned frame.
