Product Description:

The MSK100B-0300-NN-M3-RG0-NNNN servo motor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In industrial automation cells, this motor supplies finely regulated torque and speed to linear stages, rotary tables, and material-handling axes that demand precise closed-loop control. By converting the controlled output of an inverter into accurate mechanical rotation, it acts as the electromechanical actuator that synchronizes motion with neighboring drives in multi-axis packaging, printing, and assembly equipment. This operating role supports smooth acceleration, stable low-speed motion, and repeatable positioning during continuous machine cycles. It is well suited to coordinated axes where rapid response and consistent tracking are required across repeated motion sequences.

Its cooling relies on natural convection, so heat leaves the stator through the housing fins without fans or liquid circuits, keeping installation uncomplicated. The unit follows the standard design suffix, indicating that it does not include special coatings or sealing modifications. Rotor position is measured by a capacitive multiturn encoder that communicates through a Hiperface link. Within each revolution, the sensor provides 16 signal periods of position data, and its sensing principle is capacitive, which helps resist magnetic interference. Because the turn counter is multiturn absolute, the drive retains shaft position after power-up without homing moves. Electrical behavior follows winding code 0300, which gives the motor a fixed voltage constant and current range compatible with M3-class IndraDrive converters.

The assembly is delivered without a holding brake, so static loads must be restrained by drive torque or an external clamp. Power enters through a right-side radial connector that keeps cable loops clear of adjacent machinery and can simplify routing where space is limited. Output torque is transmitted by a plain shaft that is ready for clamp-style or shrink-fit couplings. A 100-frame diameter and B-length stack balance continuous torque against rotor inertia, while the plain housing mates with user-supplied seals when added protection is needed around the shaft area.
