Product Description:

The MSK100D-0350-NN-M1-RG0-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It combines a size 100 frame with a D-length stator to supply the continuous torque and dynamic acceleration required by positioning axes, pick-and-place gantries, and packaging machinery. As a standard design motor, it fits directly into compatible Rexroth drive systems without adapter plates and serves as a compact electromechanical actuator for closed-loop motion control in industrial automation. The motor is suited for applications that need repeatable speed and position control during frequent start-stop cycles.

The unit relies on natural convection for heat dissipation, so airflow around the housing should remain unobstructed during high-duty operation. A housing with an IP65 rating helps protect the windings from dust and low-pressure water jets, allowing installation on lines exposed to cleaning spray or airborne particles. The power connector is mounted on the right side of the stator, which can simplify cable routing when the motor is installed on a left-hand machine wall. Continuous service is supported in ambient temperatures from 0–40 °C, which matches common factory conditions. Because the rotor uses a plain shaft, couplings or pulleys mount directly without a keyway, which helps reduce imbalance at higher speeds. The motor is supplied without a holding brake, so static torque must be provided by an external brake or by the drive when power is off. It also uses thermal class 155 insulation, and winding code 0350 matches the electrical characteristics expected by the paired drive.

Axis feedback is delivered through a Hiperface interface that transfers position data and motor information to compatible controllers. Inside the feedback module, an optical scanning head reads an incremental track with 128 signal periods per revolution, while a multi-turn absolute counter retains position across multiple turns. This arrangement removes the need for homing after power-up, improves feedback resolution for servo loops, and helps keep velocity and position aligned with the drive’s current commands after extended shutdowns.
