Product Description:
The MSK100B-0300-NN-S1-UP0-NNNN is a synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Intended for precision positioning and velocity control in automated machinery, the unit translates drive commands into accurate rotary motion for packaging, material-handling, machining, and pick-and-place axes where consistent response is critical during continuous service in high-duty production cells. It is well suited to axes that accelerate and decelerate frequently, where stable torque response, smooth speed changes, and repeatable motion help maintain process accuracy over long operating cycles.
Heat is removed through natural convection, so airflow around the housing must remain unobstructed to maintain rated performance. The enclosure carries an IP65 rating, which prevents dust ingress and withstands low-pressure water jets for use outside a sealed cabinet. Motion feedback is handled through a rotatable 240° encoder connector that links the sensor set to the drive. The interface follows the Hiperface protocol, and the scale delivers 128 signal periods per mechanical revolution. This optical arrangement supports fine position interpolation for closed-loop control. The winding code 0300 identifies the electrical characteristics of the stator and matches compatible IndraDrive controllers.
The motor uses single-turn feedback, so absolute position is retained within one revolution but resets beyond that point. A machined shaft with keyway simplifies torque transfer to couplings or pulleys without relying only on friction fits. Operation is permitted from 0–40 °C, and the insulation system is rated for 155 °C winding temperature to support continuous drive currents without premature aging. The motor has a standard design with length code B and size 100, and it comes without a holding brake when static load retention is not required. This layout is useful in applications that already use external holding methods or drive-applied torque at standstill.
