Product Description:
The MSK070C-0300-NN-S2-UG0-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It uses frame size 070 with housing length C, giving it a compact format for positioning axes, gantry tables, and packaging machinery where installation space is limited. In operation, the motor converts electrical input into controlled rotary motion for closed-loop speed and position control. Its commutation and feedback arrangement supports precise angular positioning during repeated machine cycles.
Heat is removed by natural convection, so the motor does not require forced air or liquid cooling. The rotor and stator are produced with increased concentricity, which reduces runout and helps maintain accurate shaft rotation. For cable routing, the encoder plug is rotatable through 240°, allowing the connection to be directed around nearby components without placing unnecessary strain on the connector. Position data is transmitted through EnDat 2.1, a bidirectional digital interface that carries absolute position information and supports communication with the drive. The encoder provides 2048 signal periods, giving the control system a stable base signal for fine interpolation and responsive motion control.
The feedback system uses optical scanning and is a single-turn device, so it reports position within one mechanical revolution before repeating the count. Mechanical output is delivered through a plain shaft, which supports direct coupling to pulleys, couplings, or gearboxes that do not require a keyed connection. The stator winding code is 0300, matching the electrical characteristics expected by compatible Rexroth drive modules for this motor size. The unit is built without a holding brake, so any static load must be secured by external braking hardware or by the driven mechanism when power is removed.
