Product Description:

The MSK100B-0300-NN-M2-AG0-RSNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is used to drive axes that demand high positioning accuracy and repeatable speed in assembly lines, machining centers, and packaging modules. The unit’s 100 frame size and B-length stator provide favorable torque density while keeping the mounting pattern compatible with standard flanges. This allows the motor to fit into servo applications that need consistent dynamic response without requiring a larger mechanical envelope.

Thermal management relies on natural convection, so heat is removed through the housing fins without forced air or liquid circuits. Position feedback is supplied via an EnDat2.1 optical encoder that resolves the shaft into 2048 signal periods per revolution, and its multi-turn absolute capability retains position information across multiple revolutions. The A-side power connector groups the three-phase supply and ground on one end of the stator, which helps keep cable routing organized in compact machine layouts. The motor has an IP65 enclosure rating, protecting internal windings from dust and low-pressure water jets encountered on factory floors.

The rotor is supported by bearings selected for increased concentricity, and the overall construction is approved for explosion-protected zones where potential ignition sources must be minimized. Torque is delivered through a plain shaft, which allows the use of clamp couplings without key machining. The motor uses winding code 0300, and thermal limits follow insulation class 155, allowing continuous operation within an ambient range of 0–40 °C. Because the motor is supplied without a holding brake, stationary loads must be secured by the drive amplifier or by external locking hardware during power-off conditions.
