Product Description:

The MSK100D-0350-NN-S2-AP0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for precise rotary motion, the unit converts drive current into controlled torque for positioning tables, pick-and-place joints, or packaging spindles in automated machinery. Its mechanical layout follows an increased concentricity build that limits shaft runout, which helps maintain encoder accuracy during repeated start-stop cycles and consistent motion quality over long operating periods.

Heat dissipation relies on natural convection, so there is no external fan and the motor can be mounted where airflow is limited. For feedback, an EnDat 2.1 digital interface links the optical reader to the drive and supports automatic device identification with single-cable technology. The measuring head uses optical scanning of a glass scale that delivers 2048 signal periods per revolution, and internal interpolation lets the controller resolve very small position changes. Because the track is a single-turn design, absolute position information is available within one revolution, while multi-turn position must be tracked by the machine control if needed. The power connector is located on the A-side, which helps simplify parallel wiring in multi-axis installations.

The motor has a 100 mm stator diameter, and the length index of D balances continuous torque with manageable inertia for medium-mass loads. The winding code is 0350, matching the drive to moderate line voltages and current ratings common in packaging and material-handling systems. The motor uses a shaft with keyway for positive torque transmission, and it is supplied without a holding brake, so vertical axes require external locking or drive torque when power is removed. The rotor design also helps reduce vibration at high servo bandwidths.
