Product Description:

The MSK101D-0300-FN-M2-BG0-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The unit supplies controllable torque and speed to automated axes in packaging, metal-forming, and material-handling cells, where the motor and drive work together in a closed loop for accurate positioning and stable speed control. It uses the 101 stator frame with D length, which extends the active iron for higher continuous torque while retaining the standard 140 mm flange for machine integration.

The motor relies on liquid cooling that circulates through the stator jacket, removing heat from the copper and keeping winding temperature stable under continuous high load. Position feedback is transferred via the EnDat2.1 digital interface, so a single hybrid cable can carry encoder data while also supplying power to the encoder electronics. Inside the scan head, an optical scale with 2048 signal periods per mechanical turn feeds the drive with a dense incremental pattern, and interpolation provides very fine position data for smooth velocity control. Because the detector uses optical scanning, it is less affected by stray motor fields, and its multiturn absolute capability stores up to 4096 revolutions without battery support.

A rotor machined for increased concentricity limits radial runout, helping gear stages and couplings maintain uniform tooth loading during operation. The output uses a plain shaft, so custom hub or shrink-fit connections can be applied without keyway stress risers. Motor power exits through a connector on side B, allowing cable routing to stay clear of the driven element. Winding code 0300 matches the voltage constant expected by compatible MSK drive converters. The motor is supplied without a holding brake, so the axis must rely on external clamps or servo lock when power is removed.
