Product Description:
The MSK100B-0450-NN-M1-BG1-NNNN is a three-phase AC servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a closed-loop drive element, the motor converts electrical energy into controlled mechanical rotation for positioning tasks in assembly cells, packaging stations, and other industrial automation axes. Its design integrates an absolute encoder and an electrically released brake so the drive can start, stop, and hold loads with high repeatability. The motor is intended for servo-controlled axes where stable speed regulation and accurate position tracking are required during repeated motion cycles.
Cooling relies on natural convection, so heat generated in the stator is transferred outward without forced airflow, and adequate clearance should be left around the housing. An electrically released holding brake rated at 32 Nm keeps the shaft locked whenever control power is removed, which supports vertical axes or dwell phases under load. The housing has an IP65 rating that helps block dust ingress and low-pressure water jets. This enclosure level supports installation on machine sections exposed to airborne debris or routine cleaning spray. Torque is transferred through a plain shaft, and the absence of keyways minimizes runout and simplifies coupling alignment. Feedback is provided through a Hiperface interface that sends position and multi-turn data directly to compatible drive controllers.
The motor is qualified for ambient temperatures between 0–40 °C, and its power connector is located on the B-side to support cable routing in right-angle drive layouts. The optical encoder provides 128 signal periods per revolution and records position over multiple turns, which eliminates homing moves after power cycles. The multi-turn feedback channel helps the drive recover axis position quickly after interruptions and supports repeatable startup behavior. A thermal class of 155 allows the winding insulation to operate at elevated internal temperatures within the motor's intended duty range.
