Product Description:

The MSK100B-0400-NN-S2-AG0-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a rotary drive element that delivers closed-loop position and velocity control in automated machinery, packaging equipment, and pick-and-place axes where high dynamic accuracy is required. Its synchronous design supports responsive acceleration and stable servo behavior in applications that depend on repeatable motion. The motor is intended for servo systems in which the controller must maintain accurate motion during rapid changes in speed and load.

This motor relies on natural convection for heat dissipation, so airflow around the housing must be maintained to keep winding temperatures within limits. The housing is sealed to IP65, which helps protect internal components from dust and low-pressure water jets. The unit is supplied without a holding brake, so any power-off load retention must be handled by the machine mechanics or by drive torque. Motion feedback is provided through an EnDat2.1 optical interface. The encoder provides 2048 signal periods per revolution, and its single-turn design reports absolute position within one mechanical revolution.

The size 100 frame provides a broad stator diameter that supports higher torque density for demanding axis duties. The motor uses increased concentricity to reduce radial runout in precision couplings. A plain shaft simplifies coupling selection and avoids keyway stress concentrations. Thermal endurance is rated at Class 155, allowing continuous operation until the winding system reaches 155 °C. An ambient range of 0–40 °C allows installation in standard shop environments without derating. Power is routed through an A-side connector, while length code B and winding code 0400 match the motor to compatible IndraDrive amplifiers.
