Product Description:

The MSK101D-0300-FN-S2-AG0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into precisely controlled rotary motion for positioning, contouring, or velocity-regulated tasks inside automated machinery and robot axes. By supplying torque on demand and high dynamic response, the unit functions as the primary actuator in drive systems that pair with IndraDrive controllers across packaging, printing, material-handling, and assembly cells.

The motor has a 101 frame size and a D length variant, giving the stator enough space for winding code 0300. Heat generated in those coils is removed by liquid cooling, so the motor can sustain rated current even when mounted in sealed enclosures. The stator lamination stack is machined for increased concentricity, which helps reduce vibration at high speed. Power is supplied through an A-side connector that keeps the cable parallel to the shaft. Feedback is exchanged over the EnDat2.1 digital interface, allowing drive electronics to read absolute position and diagnostic data over a single shielded line. A plain shaft simplifies coupling to gearboxes or direct-drive loads.

Position fidelity is refined by an encoder that delivers 2048 signal periods using an optical scanning method. The single-turn track resolves absolute angle within one revolution, and the drive extrapolates multi-turn data electronically. Because the motor is supplied without a holding brake, static load retention must be provided by a mechanical locking device or closed-loop torque when required. The liquid circuit, concentric rotor alignment, and low-runout plain shaft help the sensor maintain fine resolution during thermal cycles and rapid reversals, supporting accurate interpolation for gantries, tool spindles, and indexing tables.
