Product Description:

The MSK101D-0202-NN-S3-FG0-NPNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor is intended for closed-loop industrial automation where precise torque and position control are required for axes on packaging machines, gantries, and machine tools. Its electromagnetic design allows direct connection to Rexroth drive controllers for real-time profiling and feedback control in multi-axis systems.

The machine interface uses a terminal box, so power and signal leads can be landed without pre-molded connectors, which simplifies wiring in large enclosures. Heat is removed solely by natural convection, so the motor can be installed without forced-air ducts or liquid circuits when ambient airflow is adequate. Mechanical mounting follows the B5 flange assembly pattern, giving a centering pilot and four threaded holes for rigid coupling to gearboxes or frames. Rotor position data is transmitted over the Hiperface digital channel, allowing absolute position transmission alongside incremental tracks to the drive. The sensing element is capacitive, which resists magnetic interference and maintains accuracy even when the motor is exposed to strong stray fields from nearby inductive devices.

Fine positioning is supported by an encoder resolution of 16 signal periods per mechanical revolution, and the feedback is single-turn, delivering absolute position information for one shaft turn before rollover. The stator uses winding code 0202, which sets the resistance and inductance for compatibility with mid-range MSK drives. Because the shaft is a plain shaft, couplings or pulleys must provide their own keying or clamping method. The unit ships without a holding brake, so vertical axes must rely on external brakes or the drive’s torque to maintain position. Motor size 101 and length D give a power-to-weight ratio suitable for medium-inertia loads while keeping the overall frame short for compact installations.
