Product Description:

The MSK070E-0300-NN-S2-UG1-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is intended for precision positioning and velocity control in automated machinery, where a compact 070 frame and E-length stator provide high torque density in a space-saving package. In servo applications, the motor converts current commands from the drive into controlled rotary motion for indexing, transfer, and synchronized handling tasks. It combines closed-loop feedback with a holding brake, making it suitable for packaging axes, gantry drives, and pick-and-place systems that need fast starts, accurate stops, and stable low-speed operation.

The motor uses natural convection, so no external fan or liquid circuit is required. Position data is transmitted over the EnDat2.1 digital interface, and the optical measuring system provides 2048 signal periods per mechanical revolution for precise feedback. Because the encoder is a single-turn device, the controller receives absolute position information within one turn, which supports accurate commutation and repeatable positioning after startup. An integrated brake supplies 23 Nm of holding torque when power is removed, and the housing is sealed to IP65 when the mating connectors are installed. This enclosure helps protect internal components from dust and low-pressure water exposure found in many industrial machines.

A plain shaft simplifies coupling selection and avoids keyway stress concentrations that can appear in cyclic servo duty. This shaft style works well with clamp couplings and other friction-based connections that do not require a keyed interface. Continuous operation is permitted from 0 to 40 °C, which fits typical indoor industrial conditions around production equipment. The winding insulation is class 155, giving the motor thermal capacity for repeated acceleration and deceleration cycles while supporting the current peaks common in dynamic motion control.
