Product Description:

The MSK100B-0450-NN-S1-BG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This IndraDyn S unit converts electrical power into regulated torque and speed for positioning axes in automated machinery. The motor uses size 100 with a B-length frame and a standard mechanical design, which helps it fit tightly packed packaging lines, material-handling stations, and other precision motion tasks. In closed-loop motion systems, it supports repeatable indexing and smooth axis movement during frequent start-stop cycles. Its synchronous design allows the connected drive to regulate rotor motion accurately during rapid changes in load and direction.

The housing carries a protection rating of IP65, so dust and water jets do not reach the internal windings. Heat is removed by natural convection, so no external fan or liquid circuit is required. Position feedback comes from an optical encoder that communicates over the Hiperface interface and delivers 128 signal periods per mechanical revolution, which supports stable speed and position control. The motor has a plain shaft for direct coupling to gearboxes or load shafts. Insulation class 155 supports continuous duty when the stator temperature remains within its rated limit.

An electrically released holding brake supplies 32 Nm of static torque to lock the rotor when power is removed, which helps keep vertical or suspended loads from drifting. The encoder is a single-turn device, so absolute position data is maintained within one mechanical revolution of the shaft. Ambient air temperature must remain between 0–40 °C during operation to keep the motor within its intended thermal range. A B-side power connector helps route cables when the drive connection enters from the rear of the machine. This connector location can help keep cable runs clear of nearby moving components.
