Product Description:

The MSK100C-0450-NN-M2-BG0-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. In automated production cells, this motor converts regulated electrical power into accurate rotary motion for positioning tables, packaging spindles, and gantry axes, supporting closed-loop drive systems that require repeatable speed and torque. The motor uses an optical feedback unit connected through the EnDat2.1 interface, which transmits absolute position data to the drive with reduced cabling.

Heat is removed through natural convection, so the housing must be mounted where ambient air can circulate freely without forced ventilation. Within the encoder, 2048 signal periods per revolution provide fine interpolation for smooth velocity control and stable position feedback. The housing has an IP65 rating, which provides complete dust exclusion and protection against low-pressure water jets and allows installation on machine frames without extra enclosures. The windings use insulation class 155, so the stator can withstand winding temperatures up to 155 °C before thermal limits are reached.

The optical encoder uses a multi-turn absolute system that records several mechanical revolutions, eliminating homing routines after power loss. A plain shaft transfers torque without keys and works with the increased concentricity design to minimize radial runout when the size 100, length C rotor is coupled to precision gearheads. Operation is permitted between 0–40 °C, so use outside this range requires derating or external cooling. Winding code 0450 is used for the stator variant selected for medium base speed, and the motor is built without a holding brake to keep inertia low for dynamic indexing. A B-side power connector also helps simplify cable routing along vertical machine panels.
