Product Description:

The MSK101E-0450-NN-M2-BG0-RNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The motor has size 101 with the E length code, giving it a stator stack suited for medium-to-high torque loads in packaging, printing, and material-handling axes. It uses an increased-concentricity mechanical design that reduces runout and vibration at the coupling interface. The plain shaft permits direct insertion into clamping hubs without keyways, and the unit comes without a holding brake, so any vertical load must be secured by external means.

Copper losses are removed through natural convection, so sufficient surrounding airflow is required instead of a dedicated blower or liquid-cooling circuit. Position feedback is transmitted through the EnDat2.1 digital interface, allowing incremental and absolute data to reach the drive controller over a single cable. The optical scanning system provides 2048 signal periods, and interpolation in the control electronics supports fine position resolution for precise motion. A molded enclosure with an IP65 rating blocks dust and low-pressure water jets, allowing installation on machine frames exposed to washdown or airborne coolant.

Long-range position tracking is handled by a multi-turn absolute encoder section, which keeps count of revolutions without battery support and removes the need for homing after power cycles. Electrical power reaches the stator through a connector on side B, which can simplify cable routing when the flange faces the operator. The winding system uses insulation class 155, and the permissible ambient temperature range is 0 to 40 °C. The electromagnetic circuit uses winding code 0450, which sets the resistance, inductance, and torque constant used with compatible MSK drive modules.
