Product Description:

The MSK101C-0300-NN-S2-BP0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servo motor, it delivers closed-loop torque and position control to automated equipment such as packaging stations, pick-and-place gantries, and metal-forming axes where precise motion is required. When paired with a compatible drive, it supports repeatable acceleration, settling, and contour tracking during indexing and positioning moves. Its synchronous design allows the controller to maintain precise rotor alignment as load conditions change across the cycle. This makes the motor suitable for applications that alternate frequently between standstill and commanded speed without sacrificing control accuracy.

This model relies on natural convection for heat removal, so temperature is managed by surface radiation without forced airflow. Position feedback is handled through an optical encoder that communicates via the EnDat2.1 serial interface. The scale inside that encoder divides one mechanical turn into 2048 signal periods, enabling fine interpolation of motor angle. Because the feedback is single-turn, the absolute position is unique within one revolution and external homing is required after multiple turns. A housing rating of IP65 prevents dust ingress and guards against water jets in washdown areas. Manufacturing tolerances favor increased concentricity to minimize shaft runout. The rotor uses a keyed shaft for positive mechanical locking, and power cabling exits on the B-side of the stator to simplify routing inside narrow control cabinets.

The motor is supplied without a holding brake, so static loads must be secured by the drive or by external clamps. Electrical insulation meets class 155, accommodating winding temperatures suitable for continuous duty within an ambient range of 0-40 °C. The electromagnetic profile is identified by winding code 0300, which matches the voltage constant and rated current expected by a compatible IndraDrive controller. Frame size 101 and length code C give the motor a compact, high-torque form for medium-power axes, while the mounting envelope supports installation where space is limited. That combination is useful on machine axes that need steady torque at low speed and accurate response during short positioning cycles.
