Product Description:

The MSK070E-0300-NN-M1-AP1-NNAN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It provides closed-loop speed and position control for robotic wrists, packaging indexes, and tool spindles that require dynamic yet accurate rotary motion. The housing corresponds to motor size 070 and the length designation E, giving a balanced inertia-to-torque ratio suited for mid-range drives while maintaining a compact footprint for tight mechanical envelopes.

Heat generated during operation is dissipated through natural convection, so no external fan or liquid circuit is required. The rotor and bearing stack use Reduced Run-Out, limiting radial deviation and enhancing repeatability when high interpolation factors are used. Feedback is transmitted to the drive through the Hiperface protocol, which carries both position data and electronic nameplate data over a single hybrid cable. Internal interpolation begins with an encoder disk that yields 128 signal periods per mechanical revolution, allowing the control electronics to resolve very small increments for smooth velocity loops. Electromagnetic design parameters are set by winding code 0300, aligning resistance and inductance with the thermal capability of the length E stator segment.

The sensing system uses an optical principle and a multiturn absolute encoder, storing rotation counts so the axis powers up with immediate position awareness. For static holding, an electrically released brake delivers 23 Nm of torque, keeping loads secure during power loss without affecting dynamic response. Power reaches the windings through the front-mounted A-side connector, simplifying cable routing in gantry systems. Mechanical coupling relies on a shaft with keyway, providing positive engagement that tolerates cyclical reversals common in indexing tables. Position remains available after power is restored, which helps the axis return to operation without a reference move.
