Product Description:
The MSK100B-0400-NN-M1-AP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. As a controlled rotary actuator, it converts drive current into precisely regulated mechanical motion for positioning, contouring, and process axes in automated machinery. The standard 100-frame mechanical format helps it fit servo-driven machine modules such as handling axes, indexing units, and packaging equipment, and it is intended to work with compatible Rexroth drive controllers for repeatable speed and torque response under closed-loop feedback.
Thermal management relies on natural convection, so heat is dissipated through the housing without forced airflow, and the B-length stator keeps overall mass suited to this passive cooling method. The housing has an IP65 protection rating that seals the motor against dust ingress and low-pressure water jets, allowing direct mounting outside of cabinets. A keyed output shaft provides positive torque transfer, and an electrically released holding brake supplies 32 Nm of static torque to secure vertical or suspended loads when power is removed. Rotor position is detected by an optical encoder with a Hiperface interface and 128 signal periods of line resolution, and its multi-turn absolute feature stores axis position across power cycles, which reduces the need for a homing move after startup. Power enters through the connector on side A, which can simplify cable routing in compact machine layouts.
The winding code 0400 uses class F insulation rated at 155 °C, giving the motor thermal headroom for cyclic loads while remaining within an ambient range of 0 to 40 °C for continuous duty. The B-length stack balances torque density and inertia for general-purpose handling axes, so the motor can support responsive acceleration without giving up steady running behavior. The standard mechanical layout and keyed shaft fit common couplings or gearboxes without custom machining, and the encoder’s optical design supports accurate current vector control across the permitted operating temperature range.
