Product Description:

Bosch Rexroth Indramat produces the MSK100B-0400-NN-S2-AG1-RNNN within the MSK IndraDyn S Synchronous Motors series. The unit is a servo motor used for precise torque and position control on automated axes such as gantries, packaging machines, and material-handling modules. Its electromagnetic design converts drive-amplifier command currents into tightly regulated rotary motion, letting a machine controller synchronize multiple axes with minimal following error.

Heat generated in operation leaves the stator through natural convection, so no external blower or liquid manifold is required. Housing joints and connector seals give the motor a protection rating of IP65, allowing installation in areas with airborne dust and low-pressure water jets. The electrically released holding brake supplies 32 Nm of static torque to secure vertical loads whenever the DC bus is de-energized. Position feedback comes from an optical single-turn encoder that delivers 2048 signal periods per revolution over the EnDat2.1 interface, enabling the drive to resolve very small position changes and transmit identification data. An A-side power connector simplifies cable routing toward the control cabinet, the 0400 winding code identifies electrical constants matched to MSK drive modules, and increased concentricity of the rotor and stator lowers cogging torque for smoother velocity.

The motor is built on Size 100 laminations with a length code B, balancing inertia and continuous power output. A plain shaft transmits torque directly to couplings without keyway stress concentrations, and the shaft’s internal thread aids disassembly during service. Thermal endurance is supported by Class 155 insulation, which allows winding temperatures up to 155 °C without dielectric loss. The permissible ambient range is 0 to 40 °C, which matches common control cabinet climates.
