Product Description:

The MSK100B-0400-NN-M1-RP0-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Serving as a rotary actuator, it converts controlled current from a drive into precise torque and speed for positioning axes, pick-and-place modules, and similar automation tasks. The compact frame supports direct machine mounting, and the standard housing integrates feedback and power terminations for high-resolution motion control in tight spaces. It is well suited for applications that require quick response, repeatable positioning, and stable operation through frequent start-and-stop cycles.

Cooling is handled by natural convection, eliminating forced airflow and allowing the housing to dissipate heat. Position feedback travels through a Hiperface interface that carries supply power and serial data from the optical scanning head. The sensor outputs 128 signal periods per revolution and stores angle data as a multiturn absolute value, so the drive retains shaft position after power cycling. The motor follows winding code 0400 and is built in size 100 with the B length variant to balance torque and inertia. Its layout is the standard design, the power connector exits on the right side, and the unit is supplied without a holding brake to reduce mass in servo axes that rely on drive torque for static positioning. Because the encoder information is available directly at the motor, the connected drive can monitor rotor position during acceleration, deceleration, and standstill without external sensing devices.

The motor has an IP65 enclosure that resists dust ingress and water jets, while the shaft with keyway transfers torque to couplings without shrink-fit hardware. Thermal class 155 insulation tolerates elevated winding temperatures during cyclic duty, and continuous service is specified inside an ambient range of 0–40 °C without derating. These features support installation in enclosed machinery where dependable thermal behavior and secure shaft coupling are important for daily production use. The keyed shaft format also works with many common industrial hubs and couplings, which helps simplify mechanical integration on driven axes.
