Product Description:

The MSK071C-0200-NN-S1-UG0-NNNN synchronous servomotor is built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It delivers tightly controlled rotary motion for axes that must follow precise position or speed commands in automated production cells, assembly machines, and handling equipment. As a standard-design unit in this series, it integrates with IndraDrive power stages and operates on the drive bus to form a closed-loop electromechanical actuator. Its frame size 071 housing supports compact mounting while maintaining continuous torque capacity suitable for mid-power duties. The synchronous design also allows the paired drive to regulate torque quickly during indexing, feed motion, and repeat positioning tasks.

Heat is removed by natural convection, eliminating the need for fans or coolant lines and reducing maintenance points. The cast-aluminum enclosure carries an IP65 rating, blocking dust and low-pressure water so the unit can be mounted directly on the machine frame without extra shielding. Position feedback relies on a Hiperface encoder whose connector can rotate 240°, allowing cable exit to be aligned with cabinet routing. Inside that feedback device, an optical scale subdivides 128 signal periods, giving the controller a fine digital reference for commutation and motion profiling. Because the sensing principle is optical, accuracy is not degraded by stray magnetic fields commonly present around high-current busbars. The rotatable feedback connector also helps reduce cable strain when the motor is installed in confined spaces or at unusual mounting angles.

A plain shaft output lets users couple the rotor with clamps, shrink discs, or bellows couplings without keyways. The motor is specified for ambient operation from 0 to 40 °C, matching typical cabinet or factory floor climates. Thermal endurance comes from insulation class 155, which permits elevated winding temperatures during cyclic loads. Electromagnetic properties are set by winding code 0200, which matches current and voltage characteristics to the C-length stator design. The unit is delivered without a holding brake, so static load retention must be achieved with external clamps or by maintaining drive current. This arrangement is often suitable for applications where the axis does not need a dedicated mechanical brake during standstill.
