Product Description:
The MSK070C-0450-NN-S2-UG0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary motion for positioning, feed, and handling axes used in automated assembly and packaging equipment. The motor is delivered in size 070 with a C-length stator stack and employs winding code 0450 to match IndraDrive power stages without additional parameter scaling. Applications that require load holding when power is removed can add an external brake because this unit is supplied without a holding brake. It is suited to compact, high-response automation axes.
Heat is removed from the housing by natural convection, eliminating the need for cabinet fans or liquid circuits. The rotor is machined for increased concentricity, which improves velocity stability at low speeds. Position feedback is generated by an optical single-turn encoder with an EnDat2.1 interface and a native resolution of 2048 signal periods, permitting high controller gain without excessive quantization effects. The encoder plug is rotatable through 240°, which simplifies cable routing in tight spaces. Mechanical power is transferred through a plain shaft, allowing direct coupling to gearboxes or timing belts without keyway stress concentrations.
Ingress protection is rated at IP65, enabling installation on exposed machine frames that are subject to washdown. Continuous duty is specified for ambient temperatures from 0 to 40 °C, so full torque is available across common factory conditions without derating. The windings and insulation conform to Class 155, giving thermal margin during rapid acceleration and deceleration. This combination supports accurate motion on axes that need stable low-speed rotation, responsive positioning, and a compact motor that does not require external cooling hardware.
