Product Description:
The MSK071C-0200-NN-M1-UP1-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The standard design combines winding code 0200 with size 071 and length C, placing it in the mid-torque range used in packaging lines, gantry axes, and machine-tool spindles. By pairing its sinusoidal windings with an optical feedback device, the unit converts precisely modulated drive currents into smooth rotary motion for accurate positioning and stable speed control in multi-axis automation cells. In closed-loop operation, the feedback path lets the connected drive correct motion deviations as load conditions change.
Thermal regulation depends on natural convection, so the housing fins must remain clear for air exchange during continuous duty. The frame achieves IP65 protection, sealing the stator against dust ingress and low-pressure water jets encountered near coolant sprays. Full performance is available across 0–40 °C ambient, which suits general industrial enclosures and machine-mounted installations. When the amplifier is disabled, an electrically released brake supplies 23 Nm of holding torque to keep suspended loads or indexing fixtures from drifting. Rotor position is transmitted through the Hiperface serial link, and the optical encoder delivers 128 signal periods per mechanical turn for interpolation by the drive. The encoder connector can be rotated through 240°, which helps cable routing in tight spaces.
The feedback device is a multiturn absolute encoder, so the axis retains its positional reference after power loss and does not need a homing stroke at restart. Windings use insulation class 155, allowing elevated internal temperatures without early varnish breakdown during rapid acceleration cycles. Power is transmitted through a shaft with keyway, which provides positive engagement with pulleys or gear hubs. This shaft style also supports applications where repeatable torque transfer is required during frequent starts, stops, and brake-assisted holding.
