Product Description:

The MSK100C-0300-NN-M1-LG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated production cells, it delivers precise rotary motion for indexing tables, pick-and-place heads, and articulated robot joints. The unit follows the series’ standard design envelope, integrates motor size 100 with length code C, and fits directly into machines that need high dynamic response without external cooling hardware. Its synchronous design supports accurate acceleration and repeatable positioning in motion systems that must remain stable during changing load conditions.

Thermal energy is removed through natural convection, so no fan or liquid circuit is required. The cast housing achieves a sealed IP65 rating, blocking dust ingress and low-pressure water jets encountered on factory lines. Position feedback travels over the Hiperface interface, allowing streamlined connection to compatible Rexroth drives. Within the optical encoder, each revolution is subdivided into 128 signal periods, and the internal gear set tracks multiple turns, giving a multi-turn absolute position value that eliminates homing routines after power loss. This feedback chain supports stable speed control while helping the drive maintain consistent position data during repeated start-stop cycles.

The driveline couples to machinery through a plain shaft, simplifying alignment with keyed hubs or shrink disks. Continuous service is permitted at ambient temperatures from 0 to 40 °C, matching typical industrial conditions. The motor uses insulation class 155, permitting copper temperatures up to 155 °C during intermittent overloads without insulation breakdown. Magnetic characteristics follow winding code 0300, which matches the motor to compatible MSK inverters. A left-side power connector streamlines cable routing along gantry beams, and the motor is supplied without a holding brake, so static load retention must be provided by external mechanics or the drive’s torque mode. Optical sensing technology inside the encoder supports high resolution while resisting magnetic interference generated by nearby drives.
