Product Description:

The MSK100D-0350-NN-M1-LG2-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precision motion tasks in automated machinery where accurate torque and speed regulation are required. It is suited to packaging, handling, and other servo-driven systems that depend on repeatable positioning during frequent starts, stops, and speed changes. The motor integrates a multiturn absolute encoder for continuous position feedback and includes an electrically released holding brake so vertical or suspended loads remain secure when power is removed.

Cooling relies on natural convection, so heat is dissipated through the housing without forced airflow, which simplifies installation in sealed cabinets. The enclosure carries an IP65 rating, which keeps dust out and protects internal components from low-pressure water jets. An electrically released brake supplies 70 Nm of static holding torque so the rotor stays locked during downtime. Position data is derived from an optical encoder that resolves 128 signal periods per mechanical revolution, and this information is exchanged with the drive over the Hiperface interface. This feedback path allows the controller to monitor shaft position during motion and after power interruptions.

The encoder’s optical scanning principle minimizes hysteresis, while its multiturn absolute design records up to 4096 shaft revolutions for power-off position recall. A plain shaft transmits torque directly to couplings without keyways, reducing shaft runout. That shaft style is commonly used with friction-locking couplings where a keyed connection is not required. Continuous service is supported within an ambient range of 0 to 40 °C, and insulation class 155 permits winding temperatures up to 155 °C. The motor has size 100, length D, a left-side power connector, and winding code 0350, which affect the mounting footprint, cable routing, and voltage constant used by the drive.
