Product Description:

The MSK100A-0450-NN-S1-BP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor serves as a rotary actuator in closed-loop industrial automation, converting drive current from a Rexroth inverter into controlled torque and position for packaging lines, handling gantries, and metal-cutting axes. In servo systems, that role allows the axis to follow commanded speed and position changes with consistent response during repeated start-stop duty. The motor uses a standard design with a keyed shaft for positive torque transfer to pulleys, couplings, or gearboxes.

Thermal dissipation depends on natural convection, so the housing surface removes heat without an external fan or liquid circuit. Position feedback is delivered through a Hiperface interface, which carries absolute position data between the motor and the drive. The integrated encoder produces 128 signal periods, and because it is optical, the sensing system is not affected by magnetic stray fields from nearby power cables. Its feedback disk is single-turn, so the motor provides one absolute angle reference per revolution and suits axes that use external homing after a full mechanical rotation.

Load-holding performance is provided by an electrically released brake rated at 32 Nm, allowing vertical axes to remain immobile when power is off. Frame code 100 matches the stator diameter used for MSK gearheads or direct-drive flanges of the same size. Power and signal conductors exit on the B-side, which can help route cables away from the machine working envelope. The winding code 0450 sets the electrical characteristics expected by the matching drive and supports a fixed current-to-torque relationship. Motor length A keeps the housing compact within this frame size, and the standard balance class supports smooth rotation in general automation service.
