Product Description:

The MSK100B-0400-NN-M1-LG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The unit supplies controlled rotary motion for industrial automation axes, allowing coordinated positioning and velocity regulation when used with an IndraDrive servo amplifier. A plain shaft couples directly to gearboxes or load flanges, and the housing uses a left-side power connector so cable routing can better match compact cabinet layouts. This arrangement supports precise axis movement in production equipment where repeatable speed control and accurate positioning are required. Because the motor operates as part of a servo system, motion quality depends on the paired amplifier and the feedback exchange between both devices.

Frame size 100 gives the motor its stator diameter and provides the torsional rigidity needed for medium-power feed axes. The length code B extends the active iron stack, increasing torque without changing the mounting pattern. Stator winding code 0400 corresponds to electrical resistance and inductance values that help the motor reach rated current quickly while keeping losses moderate. Heat is removed by natural convection, which eliminates external fans and keeps the cooling method simple where airflow is unrestricted. For plant-floor contamination control, the enclosure carries an IP65 protection rating that helps seal internal components against dust ingress and low-pressure water jets encountered during washdown.

The feedback subsystem uses a Hiperface digital interface that sends position data and electronic nameplate information to the drive. An optical sensor tracks 128 signal periods per mechanical revolution, and the multiturn absolute feature retains shaft position across power cycles for homing-free restarts. Because the motor is supplied without a holding brake, external clamping or drive torque must secure vertical loads at standstill. The standard insulation system is rated to class 155, allowing continuous operation in ambient temperatures from 0 to 40 °C. This feedback arrangement helps the drive recover actual shaft position immediately after power returns, reducing the need for reference moves on machines that cannot tolerate unnecessary motion.
