Product Description:

The MSK100C-0301-NN-M1-BG2-NSNN is a servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact, brushless AC unit, it converts drive-controller output into precise rotary motion for positioning axes and continuous-duty automation tasks on packaging lines, material-handling gantries, and machining centers. Its construction integrates a feedback encoder, power connection, and mechanical interface in a sealed housing so it can be mounted directly to gearboxes or load couplings without auxiliary enclosures. The brushless design supports repeatable motion control during frequent start-stop cycles and sustained servo operation.

Heat is removed by natural convection, allowing the motor to operate without external fans when airflow around the frame remains unobstructed. The motor has size 100 and length code C. A plain shaft provides backlash-free coupling, and the power leads exit on the B-side of the housing for orderly cable routing. The motor is intended for standard service and can also be used in explosion-protected zones. Position feedback uses an optical encoder over Hiperface; it provides 128 signal periods per revolution and stores absolute position data through a multi-turn absolute architecture. An electrically released holding brake supplies 70 Nm of static torque so vertical axes can remain locked when the controller disables motor current.

The housing is sealed to IP65, which helps block dust ingress and protects internal assemblies against low-pressure water jets. Continuous duty is supported at ambient temperatures from 0–40 °C, and the motor windings use insulation class Class 155 to tolerate elevated internal temperatures during operation. Winding code 0301 indicates the electrical values used by matched drive controllers, including resistance, inductance, and torque-constant data. Those values are used by the controller to regulate motor current and motion accurately during operation.
