Product Description:

The MSK101D-0300-NN-M1-BG0-NNNN is an IndraDyn S synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a rotary actuator, it converts electrical energy from the drive into precise shaft motion for closed-loop speed and position control on conveyors, pick-and-place arms, and other industrial axes. Its construction integrates stator windings, rotor magnets, and a single-cable feedback interface to simplify machine wiring. This layout helps reduce the number of separate motor connections while keeping the feedback path closely matched to the drive.

Thermal management is handled by natural convection, allowing the housing to dissipate heat without external fans. The motor uses size 101 with length code D, giving a larger active section than smaller members of the same family and supporting higher continuous torque in a similar mounting style. Position information is supplied through a Hiperface encoder that carries power and data on one hybrid cable. Its scanning system resolves 128 signal periods per revolution, and the optical principle offers high immunity to magnetic fields and stable signal quality. Because the feedback is multi-turn absolute, the drive can read shaft position and up to 4,096 mechanical turns immediately after power returns, which reduces startup delay on axes that must resume from a known position.

The winding designation 0300 identifies the electrical characteristics used with the matching drive. Power is supplied through an angled connector on side B, which helps keep the cable clear of nearby machine components and supports compact routing where space is limited. The motor has a plain shaft and is supplied without a holding brake, so torque transmission is handled by the attached coupling and static holding must come from drive torque or an external clamp.
