The Bosch Rexroth synchronous motor R911377391 (MSK100D-0300-NN-M2-BP2-RNNN) is an IndraDyn S series servomotor featuring a size 100 and length D configuration. It operates with natural convection cooling and integrates a multiturn absolute optical EnDat2.1 encoder with 2048 signal periods for position feedback. The motor shaft includes a keyway for torque transmission, and a 70 Nm electrically-released holding brake is present. Key electrical specifications include 0.35 ohm winding resistance, 5,650 mH inductance, a continuous current of 24.8 A at standstill (100 K), and a maximum current of 93.2 A. Performance ratings indicate up to 187 Nm maximum torque, 72 Nm continuous torque, and operation up to 3000 RPM. The rotor utilizes permanent magnets for low inertia, and a temperature sensor is integrated for thermal monitoring. The enclosure meets IP65 standards, specifying resistance to dust and liquid ingress. The power connector is located on the B-side, and the unit should be operated between 0 and +40 °C. This model is not available with motor length A.

What feature enables the MSK100D-0300-NN-M2-BP2-RNNN to hold position during unpowered conditions on vertical axes?

It includes a 70 Nm electrically released holding brake. This ensures secure shaft locking when power is disconnected or during emergency stops.

How does the encoder support reliable control in multi-turn closed-loop motion systems?

It uses a multiturn absolute optical encoder with EnDat2.1 interface. This provides precise position tracking and consistent feedback for synchronized multi-axis applications.

What allows the MSK100D-0300-NN-M2-BP2-RNNN to maintain thermal stability in fanless installations?

It relies on natural convection cooling to manage internal heat. This supports continuous operation without active ventilation in sealed or low-maintenance enclosures.

What torque capacity supports holding or low-speed clamping in industrial positioning systems?

The motor provides 57 Nm continuous torque at standstill. This ensures stable force output under static load conditions without loss of accuracy.

What enables this motor to handle aggressive acceleration phases in high-speed automation?

It delivers a peak torque of 187 Nm under full load. This allows quick torque response during dynamic motion events without thermal overload.
